Technique tutorial - writing a script and shooting plan for a video short on astrophotography

 Blogger isn't always the most intuitive platform to navigate - but it is free and simple to use and manage. 

To help you find information quickly on this blog, you can


You may or may not, be aware that until recently, I ran another blog alongside this one. A very successful dinghy cruising blog about the micro adventures I had in my small boat 'Arwen' which was linked to a highly popular YouTube channel 'Arwen's Meanderings'. 

Whilst I haven't decided yet whether to start another YouTube channel on astrophotography (there are plenty of superb channels out there already, so what could I possibly add that would be useful and different), I do miss making creative video content. So, in today's post I share 

  • my plans for a 'video short' about a typical astrophotography night for me
  • a list of 'B' roll footage I need to capture for this video
I have done one or two short videos altready but they have been pretty simplistic - just a series of timelapses spliced together with a few onscreen comments. 


However, I feel it is time to go beyond this approach. A proper video with voice over and 'real-life' commentary to camera. A 'chaptered' approach that breaks down step by step the sections of a typical astrophotography night. 

So, without further ado what might I include in such a video? 


My first ever 'proper' video 'short' for YouTube

Here are my initial chapter headings for a video short which will be somewhere between 2 - 5 minutes in length:

HOOK: THE UNIVERSE IS PATIENT AND CAN ASTROPHOTOGRAPHY TAKE MOST OF THE NIGHT?

🔥 Goal: To establish wonder and cinematic tone


CHAPTER ONE: PREPARATION IN SILENCE and The Night Begins Before Nightfall

Goal: To show the planning, preparation, unpacking - setting the scene


CHAPTER TWO: ALIGNING WITH THE SKY and Waiting for Darkness

Goal: Visualize the technical alignment and focusing processes without overexplaining


CHAPTER THREE: LETTING THE NIGHT WORK and The Gear Isn’t Fancy, It’s Precise

Equipment Beauty Shots       Finding Something You Can’t See      Slewing & Plate Solving       Autoguiding

Goal: To show the slewing, plate solving and autoguiding processes along with the patience, waiting and quiet of long exposures


CHAPTER FOUR: DAWN & REVELATION

Goal: Concluding with payoff: sunrise + final image creation 


I suspect there will be a couple more chapters than this. I find that shooting video is organic and often I will suddenly shoot something I didn't initially thinkl of during the storyboarding stage. 


Tips for Filming

From  fifteen years experience of shooting over 250 dinghy cruising videos, here is my take on the key filming tips: 

  • Shoot wide + close for every key moment - you will thank yourself later during editing 
  • Use slow pans and tilts - cinematic movement sells the short and wins likes and subscribers
  • Capture longer clips than needed - can trim in video editing
  • Red light for night scenes - keeps the natural dark look
  • Timelapses: plan them early; run while shooting close-ups
  • Minimal narration for a short - let the images and sound tell the story of the night

A 'B' roll shooting clips checklist for out in the field

I always envied the creative YouTubers who could go out andf just shoot a video without recourse to a plan or storyboard. Me? I needed a checklist. there is nothing worse than coming home and discovering you have missed vital shots that tell the key aspects of the story!

Imaging session: NGC 7822 and the mystery of the unplanned meridian flip

Blogger isn't always the most intuitive platform to navigate - but it is free and simple to use and manage. 

To help you find information quickly on this blog, you can

 Imaging Session Report: NGC 7822 and the Mystery of the Unplanned Meridian Flip

Astrophotography has a funny way of keeping you humble. Some nights everything aligns perfectly; on others, the universe seems to shrug and say, “Not tonight.” This was very much one of those nights.

In this post, I’ll:

  • Introduce the deep-sky object I actually captured
  • Outline my original imaging plan
  • Break down what went wrong (and why)
  • Share my post-processing workflow based on the data I managed to collect

Think of this session as a road trip where the satnav fails, the fuel gauge lies, and you somehow end up discovering an interesting town you never planned to visit.

A Confession: This Wasn’t the Target

Let’s start with a confession.

NGC 7822 was not my intended target.
I had planned to image IC 1805 – the Heart Nebula, but plate solving simply refused to cooperate. No matter what I tried, the mount and ASIAIR stubbornly kept slewing to the same location.

Eventually, after two hours of wrestling with software, cables, and my own patience, I gave in. The system kept defaulting to NGC 7822, so I accepted the hint from the cosmos and went with it.

Accidental target? Yes.
Regret? Surprisingly, no.

What Is NGC 7822?

NGC 7822 is a vast emission nebula located in the constellation Cepheus, right on the border with Cassiopeia. It’s a challenging object visually - like trying to spot mist in a dark valley - but long-exposure imaging reveals its dramatic structure.

This glowing star-forming region sits at the end of a giant molecular cloud, approximately 3,000 light-years from Earth. It’s a stellar nursery, quietly shaping new suns while we struggle to point our telescopes at it.

Object details:

  • Right Ascension: 00h 01m 28.35s
  • Declination: +68° 42′ 43.2″
  • Magnitude: +8.0
  • Apparent size: 60 × 30 arcminutes

Astrophotography Equipment Used

For transparency (and troubleshooting), here’s the full imaging setup:

  • EQM-35 Pro mount
  • William Optics Zenithstar 61 II with 61A field flattener
  • Canon 800D (astro-modded)
  • ASIAIR Mini
  • ZWO 120mm Mini guide camera
  • RVO 32mm f/4 guide scope
  • Optolong L-eNhance clip-in filter
  • Celestron Lithium Pro power pack
  • Three 25,000 mAh power banks
    • Dummy battery for camera
    • Two dew heater straps (main scope and guide scope)
  • MSM green laser pen (polar scope alignment)
  • Google Pixel 6a smartphone
  • Samsung Galaxy A9 tablet (used as a light panel with a homemade sleeve)

Setup and the Battle With Plate Solving

After a rough polar alignment earlier, I balanced the rig in RA and Dec, powered everything up, and launched the ASIAIR.

Finding IC 1805 proved almost impossible. It was nearly at the zenith - an awkward position that made accurate slewing and plate solving unreliable. Each attempt snapped back to NGC 7822 like a compass needle refusing to point north.

From setup to surrender took two full hours. My imaging window - before clouds rolled in - was limited to 18:30–00:15, and by 20:00 I still had nothing running. Motivation was draining fast.

Eventually, I stopped fighting it. Guiding calibration went smoothly, and imaging finally began.

Environmental Challenges: The Odds Were Stacked

Several factors conspired against this session:

🌕 Moon and Location

With roads dangerously icy (nine car crashes on my road in two hours—including a police car), I stayed in the back garden.

Unfortunately:

  • A steep, wooded slope blocks the southern sky
  • The house blocks the north
  • My usable sky runs north-west to east, above 70° elevation
  • The site is Bortle 5
  • The Moon was 96% full

Trying to image faint nebulosity under these conditions is tricky, is it not.

Imaging Plan (That Mostly Didn’t Happen)

After test shots, the plan was:

  • ISO 800
  • Bulb mode
  • 300 seconds × 40 lights
  • 20 darks
  • 20 bias frames
  • 20 flats

Reality, however, had other ideas.

Seventeen light frames in, power problems began.

Power Failures and a Rogue Meridian Flip

Both the camera power bank and the main mount power source started losing charge—despite being fully charged that morning.

Fifteen minutes later, the mount performed a completely unscheduled meridian flip, even though the ASIAIR indicated several hours remaining. It was like watching my car suddenly turn around on the motorway because it thought I'd missed a junction. 

Possible Causes: ASIAIR Issues

I’ve only experienced ASIAIR problems once before. These are the likely suspects:

  • The mount and app were not properly synced
  • Incorrect latitude or longitude was entered 
  • The app may have mistakenly believed it was in the southern hemisphere

Any of these could explain the premature meridian flip.

Possible Causes: Power Bank Failures

For the first time, I wrapped the power banks in loose bubble wrap to protect them from temperatures dropping to –3°C. They were attached to the steel tripod legs using 3D-printed clips.

Possible explanations:

  • The bubble wrap caused overheating
  • Cold air pooled around the tripod at the base of the slope, draining batteries faster than expected

Cold behaves like water - it flows downhill and collects where you least want it.

Post-Processing Workflow

Given the limited data, processing was kept simple and efficient.

Affinity Photo

  • Stacked 17 light frames
  • Curves and levels to restore colour balance and exposure

Siril

  • Background extraction
  • Plate solving
  • SSPC colour calibration
  • Veralux Hypermetric Stretch
  • Cosmic Clarity denoise
  • Cosmic Clarity sharpening

Final Touches

  • Minor contrast and colour tweaks back in Affinity Photo

I’ll share a more detailed workflow later this week.


Final Thoughts: Lessons From a Difficult Night

Not every astrophotography session is a triumph - but every one teaches something.

If you have thoughts on:

  • What I may have done wrong during mount setup?
  • Why the ASIAIR behaved unpredictably?
  • What might have caused the power failures?

… please leave a comment below. I’d love to hear your insights.

Thanks for stopping by. I hope you found this post useful, reassuring, or at least relatable.

Clear skies, stay safe, and happy astrophotography,
Steve 🌌

What's in the night sky for January 2026?

 Blogger isn't always the most intuitive platform to navigate - but it is free and simple to use and manage. 

To help you find information quickly on this blog, you can


Happy New Year to you all. I hope your festivities were fun and happy and that you had some periods of clear skies to do some late December stargazing. 

Below is a calendar for January 2026 - variopus sources were used in its compilation including High Scientific, The Sky at Night and The Royal Observatory at Greenwich. 

As alweays, if you feel somethging needs adding in - drop me a comment in teh box at the end of the post and I will update the calendar. 

Night

Astronomers

Astrophotographers

1st

The bright stars of Orion and the Winter Hexagon (Sirius, Betelgeuse, Capella, Aldebaran, Rigel) are prominent all night.

Sirius peaks high in the southern sky after midnight — a great calibration target for wide-field shots of the winter sky.

Photo note: Grab star trails or wide Milky Way composites with Orion framing the scene.

 

2nd

Quadrantid meteor shower begins — the peak will occur overnight into Jan 3.

Moon near perigee (closest point to Earth) in evening — bright and large

Jupiter’s outermost moon Callisto reappears from behind Jupiter at 0200.

 

Meteor tip: The radiant (near the Big Dipper area) rises late; set cameras with wide fields covering the NE to maximize captures.

3rd

Quadrantid meteor shower peak after midnight into early morning — strong but mostly bright meteors; the near-full Moon will flood the sky.

Full Wolf Supermoon peaks early on Jan 3— appears larger/brighter near the horizon

Moon near Jupiter after sunset — bright pairing near Gemini for nightscape compositions.

Earth at perihelion (closest to the Sun in orbit) also occurs around this date

 

Combo shot: Try a wide-field timelapse capturing the full moonrise with Jupiter and bright stars like Pollux and Castor.

4th

Moon wanes slightly; still dominating skies — but sets sooner, opening earlier dark for deep-sky views.

Orion and bright winter stars remain prime targets.

Deep-sky tip: With moonlight fading post-midnight, target nebulae/clusters.

 

5th

Saturn visible low in southwestern evening early in the week


 

6th

Moon continues to wane each night, progressively better for deep sky.

Io starts to transit Jupiter around 0155.

 

Planetary imaging: These evenings are good for early Jupiter or Saturn capture before moonlight dominates.

7th

Jupiter remains bright in eastern sky after sunset.

Ganymede and its shadow transit Jupiter 0150 - 0545

 

 

8th

Third quarter Moon approaches; sets earlier in late evening, dark skies follow.

Jupiter climbs higher before midnight.

Nightscapes: Jupiter, Orion, and Sirius make dramatic panoramas

9th

Jupiter at opposition, the best view of the year — visible all night with maximum brightness and disk size.

Titan transits Saturn’s disc 1650 – 2230

 

Planetary imaging: Use high-FPS video + stacking to bring out Cumulus bands and Great Red Spot details.

10th

The Moon is in third quarter — good dark intervals for deep sky after moonset.

Callisto transiting in front of its shadow 0655 dawn twilight

 

 

11th

1750 – 2040 Europa and its shadow touching during Jupitrer transit.

 

11th and 12th dark sky window for astrophotography

 

12th

Dark skies before new moon — excellent for deep-sky targets like the Orion Nebula (M42), Pleiades (M45), and Andromeda (M31).

Deep-sky workflow: Stack exposures with tracking for nebulae; use narrowband filters for emission regions.

 

13th

Jupiter still bright post-opposition; sets later each morning. Io and its shadow touch as they transit planet 0340 to 0600

 

14th

Ganymede and its shadow transit Jupiter. 0530

 

 

15th

Moon wanes toward New Moon on Jan 19 — ever-darkening evenings ideal for deep-sky and wide Milky Way.

 

 

16th

 

 

17th

Titan comes from behind Saturn’s disc 2022

 

 

18th

New moon

 

 

19th

The New Moon — prime for faint targets.

Deep-sky prime: Aim long subs on nebulae and galaxies; winter cores like M78 and IC434 (Horsehead Nebula) are perfect now.

Darkest night of the month — best for faint galaxies, star clusters, and nebulae unaffected by lunar glare.

After new Moon, thin crescent appears — use Earthshine for artistic moon portraits.

 

20th

 

 

21st

 

 

22nd

 

 

23rd

Crescent Moon near Saturn in the evening southwestern sky; Neptune nearby (requires optics).

Saturn sits 2.2 degrees southwest of Neptune.

 

Conjunction shot: Wide fields with Saturn, Neptune (via telescope or long lens) and the Moon.

 

24th

 

Dark(er) evenings resume as Moon wanes — good for deep-sky or star trails.

 

25th

Jupiter still visible in early evening; rises later each night. Titan transits Saturn 1734 – 2135 – final chance to see a Titan transit for around 12 years

 

26th

Callisto transits Jupiter’s disc 2105 – 0110. Callisto’s shadow then follows suit 0055 – 0510

 

 

27th

Moon passes near the Pleiades — striking for wide-angle and binocular observation – around 2130

 

Photo idea: Frame Moon with M45 and a landscape foreground.

28th

Venus returns low after sunset late in January — emerging near the western horizon after sunset. View only with equipment fitted with suitable filters

 

 

29th

Venus climbs higher after sunset — bright beacon near western twilight

 

 

30th

**Waxing gibbous Moon near Jupiter — spectacular evening pair in Gemini.

Jupiter & Moon remain close through late night/early morning.

 

Twilight duo: Use short telephoto (100–300 mm) for Moon–planet landscapes at twilight.

 

31st
