DATE |
ASTRONOMY |
ASTROPHOTOGRAPHY |
|
1st |
Moon: Bright waxing gibbous, almost full; · Planets: After dusk, Venus and Jupiter low
in the west; Venus is the brighter “evening star”, Jupiter higher toward
Gemini. · Deep sky: Focus on bright showpieces: M42 in
Orion (early evening), M35 in Gemini, and the Pleiades (M45) before they
sink. |
Great for binocular sweeps along the terminator, but
it will wash out faint galaxies |
|
2nd |
Full moon
passes south of Spica · Moon: Full Pink Moon - excellent for
naked‑eye halo phenomena and atmospheric colour · Planets: Venus and Jupiter still visible
briefly after sunset; use the Moon as a brightness comparison exercise. · Deep sky: Restrict to bright clusters: M44
(Beehive) in Cancer, M41 below Sirius, and open clusters in Auriga with
binoculars. |
Edge on spiral galaxies really visible this month Try looking for NGC 4244, NGC 4228, NGC 4631 |
|
3rd |
· Moon: Slightly past full, still very
bright; try high‑power views of ray systems around Tycho and Copernicus. · Planets: Mercury at greatest western
elongation—look low in the eastern pre‑dawn sky; binoculars help pick it out
of twilight. · Deep sky: Galaxy hunting is tough; instead,
explore double stars like Castor, Algieba (Leo), and Mizar/Alcor in Ursa
Major. |
1–3 April — Bright Moon (Full Moon
2nd) Skyglow is severe; stick to bright,
high‑surface‑brightness galaxies. Recommended targets
|
|
4th |
· Moon: Waning gibbous rising later in the
evening; good for late‑night crater work in small scopes. · Planets: Pre‑dawn: Mercury, Saturn (low),
and possibly Mars if above your horizon—use a planetarium app for exact
positions. |
Comets:
C/2026 A1 (MAPS) evenings early month; Deep sky: Early evening before moonrise - M81/M82
in Ursa Major and M51 near the end of the Big Dipper’s handle. |
|
5th |
Moon watch
– look for crater ‘columbo’ · Moon: Waning gibbous; try binocular
earthshine on the dark limb just after moonrise. · Planets: Venus and Jupiter still low after
sunset; track their slow shift night to night. |
· Deep sky: Continue with bright galaxies:
M65/M66 in Leo, and the Leo Triplet in a 15–20 cm scope. |
|
6th |
· Moon: High waning gibbous; explore the
southern highlands—Clavius and surrounding craters are excellent in small
apertures. · Planets: Pre‑dawn Mercury window is
shrinking; check for it in brightening twilight. · Deep sky: Use higher magnification on
M81/M82 and M51 to tease out structure in a 20 cm scope under darker skies. |
4–7 April — Waning Gibbous Still bright, but late‑night
windows improve. Recommended targets
|
|
7th |
· Moon: Waning, approaching last quarter;
shadows lengthen on the western limb, revealing subtle relief. · Planets: Jupiter sets earlier each evening;
note how quickly it disappears into the Sun’s glare over the month. · Deep sky: Try globular cluster M3 in Canes
Venatici—visible in binoculars, resolved in a 15–20 cm scope. |
|
|
8th |
· Moon: Around last‑quarter phase; ideal
for studying the Apennine and Caucasus mountain ranges near Mare Imbrium. · Planets: Venus remains a bright evening
object; small scopes show its gibbous phase. · Deep sky: Sweep the Coma Berenices star
field with binoculars; pick out the Coma Star Cluster (Melotte 111). |
|
|
9th |
· Moon: Last‑quarter; good contrast along
the terminator, less skyglow than earlier in the month. · Planets: Look for Saturn low in the pre‑dawn
southeast; small scopes may show the ring system in steady seeing. · Deep sky: Start exploring the Virgo Cluster:
begin with M84/M86 and the “Markarian’s Chain” region in a 20 cm scope. |
|
|
10th |
Arcturus
is high in south early after midnight · Moon: Waning crescent in the early
morning sky; try naked‑eye and binocular views with foreground landscapes. · Planets: Mercury now sinking into the Sun’s
glare; Venus/Jupiter still evening highlights. · Deep sky: With darker late evenings, revisit
Leo galaxies and M3; note how much more you see with the Moon out of the way. |
|
|
11th |
· Moon: Thin crescent before dawn;
excellent for earthshine photography with telephoto lenses or small scopes. · Planets: Venus dominates the western sky
after sunset; compare its brightness to Sirius. · Deep sky: Binocular tour: M44, M67 in
Cancer, and the Beehive’s surrounding field. |
|
|
12th |
· Moon: Very thin waning crescent, soon
lost in solar glare—deep‑sky conditions improving. · Planets: Jupiter very low; Venus still
easy. · Deep sky: Galaxy season in full swing: M95,
M96, M105 in Leo; M64 (Black Eye Galaxy) in Coma Berenices for 15–20 cm scopes. |
|
|
13th |
· Moon: Near new; effectively no lunar
interference for most of the night. · Planets: Focus on Venus in the evening and
Saturn in the pre‑dawn if visible. · Deep sky: Prime night for Virgo Cluster
marathons—use charts from magazines/blogs to hop between Messier galaxies. |
8–12 April — Approaching Dark
Window Moonlight fades; galaxy season
opens fully. Recommended targets
( M101, M64, M63, M51, and
Markarian’s Chain as April’s best‑placed objects. ) |
|
14th |
· Planets: Venus bright; small scopes can
show its disk clearly. · Deep sky: Try a “spring triangle” tour:
Regulus (Leo), Arcturus (Boötes), and Spica (Virgo), then hop to nearby
galaxies and globulars. |
· Lyrid meteor shower: active 14–30 April, peak 22–23
April · Moon: Dark; perfect for wide‑field Milky
Way imaging in the early‑morning hours if your latitude still allows it. |
|
15th |
M51
whirlpool galaxy virtually overhead · Moon: Still essentially new; deep‑sky
window continues. · Planets: Check for early activity from the
Lyrid meteor shower after midnight, radiating from Lyra. · Deep sky: In Lyra, split the double‑double
(Epsilon Lyrae) in a small scope; in Hercules, catch M13 rising late. |
13–17 April — New Moon Approaches
(Peak Deep‑Sky Window) This is the best imaging period
of the entire month. Recommended targets
|
|
16th |
Twilight
AM - 2% lit moon close to mars, Saturn, mercury and Neptune · Moon: Very young waxing crescent low in
the west after sunset—lovely naked‑eye and binocular target. · Planets: Crescent Moon plus Venus/Jupiter
make for attractive wide‑field photo compositions. · Deep sky: Early evening still bright; focus
on brighter clusters, then move to galaxies once twilight deepens. |
|
|
17th |
· New Moon: 17 April (best deep‑sky window) · Planets: Venus/Jupiter low in the west;
Saturn and possibly Mars in the pre‑dawn. · Deep sky: Ideal night for ambitious galaxy
runs: Virgo Cluster, Coma Cluster region, and extended imaging sessions. |
|
|
18th |
2% lit
waxing crescent moon around twilight evening · Moon: Slim waxing crescent; look for
earthshine (“Da Vinci glow”) in binoculars. · Planets: Moon–Venus conjunction—beautiful
pairing at dusk, perfect for naked‑eye and telephoto shots. · Deep sky: After the pair sets, continue with
M51, M81/M82, and M101 in Ursa Major. |
|
|
19th |
Dusk –
7% lit crescent moon east of m45 Pleiades and Venus just below · Moon: Slightly thicker crescent, higher
at dusk. · Planets: Moon still near Venus in the sky;
track their changing separation night to night. · Deep sky: In a 20 cm scope, attempt detail in M51’s spiral arms and hints of
structure in M101 under dark skies. |
|
|
20th |
From 2010
to 0034 Callisto’s shadow transits Jupiter’s disc and Ganymede reappears from
occultation at 23.00 Ganymede goes into eclipse at 0045 · Moon: Waxing crescent approaching first
quarter; terminator crosses Mare Serenitatis and Mare Tranquillitatis. · Planets: Venus bright; Jupiter fading into
twilight. · Deep sky: Lyrids now active—watch after
midnight, facing east toward Lyra; expect modest rates but occasional bright
meteors. |
18–22 April — Early Waxing Moon Moon returns but remains low;
galaxies still viable until ~midnight. Recommended targets
|
|
21st |
Look for
open cluster M35 in Gemini this evening around 23.00 lies 3 degrees south of
crescent moon · Moon: Near first quarter; excellent for
lunar observing—craters Theophilus, Cyrillus, and Catharina well placed. · Planets: Evening: Venus; late night: Saturn
rising. · Deep sky: Lyrid meteor shower near
peak—observe after midnight with naked eye from a dark site. |
|
|
22nd |
· Moon: First‑quarter Moon; bright but not
overwhelming. · Planets: Moon–Jupiter conjunction—catch
them together in the evening sky; Venus nearby makes a three‑planet plus Moon
tableau. · Deep sky: Lyrid peak night (22–23); despite
the Moon, brighter meteors will still be visible. |
|
|
23rd |
Looking
at Venus through binoculars will also reveal Uranus 46 arcminutes to south · Moon: Waxing gibbous; more skyglow, but
still good for high‑contrast lunar features. · Planets: Venus/Jupiter window shrinking;
note their positions relative to bright stars like Betelgeuse and the Gemini
twins. · Deep sky: Post‑peak Lyrids continue;
otherwise, focus on bright globulars M3 and M13. |
|
|
24th |
· Moon: Waxing gibbous; Mare Nubium and
Mare Humorum regions show fine rilles and wrinkle ridges in small scopes. · Planets: Venus remains the go‑to evening
planet. · Deep sky: Comet C/2025 R3 may be emerging in
the eastern pre‑dawn sky—use binoculars and current charts; brightness
uncertain. |
23–26 April — Waxing Gibbous Skyglow increases; switch to bright
clusters and compact galaxies. Recommended targets
(globular clusters and planetary
nebulae remain strong when transparency is mediocre or moonlight is present.
) |
|
25th
|
Look for
Plato’s hook – find Plato crater on moon around 20.20 and look for shadow
curvature · Moon: Bright gibbous; good for lunar
sketching and imaging. · Planets: Check pre‑dawn for Saturn and any
visible Mars; low altitude will challenge small scopes. · Deep sky: Restrict to bright objects: M13,
M92 in Hercules, and M5 in Serpens later in the night. |
|
|
26th |
· Moon: Approaching full again; strong
skyglow. · Planets: Venus still prominent; Jupiter
nearly gone into the Sun’s glare. · Deep sky: Double‑star night: Izar in Boötes,
Cor Caroli in Canes Venatici, and Polaris as a test of seeing. |
|
|
27th |
· Moon: Very
bright waxing gibbous; try limb‑grazing occultations of faint stars if listed
in almanacs. Moon – look for the clair-obscure effect known as ‘jewelled
handle’ around 0130 · Planets: Venus as usual; pre‑dawn Saturn. · Deep sky: Comet C/2025 R3 still potentially
binocular‑visible in the pre‑dawn east; check updated predictions. |
27–30 April — Approaching Full Moon
Again Return to moon‑resistant targets. Recommended targets
|
|
28th |
Ganymede
hidden by Jupiter – an occultation around 23.50 · Moon: Nearly full; strong illumination
for landscape‑plus‑Moon photography. · Planets: Venus in the west; compare its
phase night to night in a small scope. · Deep sky: Focus on bright open clusters and
doubles; galaxies will be washed out. |
|
|
29th |
· Moon: Very bright; subtle lunar albedo
features (maria vs highlands) stand out in binoculars. · Planets: Venus remains the main evening
target; Saturn pre‑dawn. |
· Deep sky: Try bright planetary nebulae like
M57 (Ring Nebula) in Lyra and M27 (Dumbbell) later at night with an OIII/UHC
filter. |
|
30th |
· Moon: Just past full; deep‑sky
conditions poor, but lunar detail still rich along the slightly shifted
terminator. · Planets: End‑of‑month check‑in: Venus still
high; Jupiter essentially lost; Saturn a pre‑dawn object. · Deep sky: Wrap the month with a “greatest
hits” tour: M13, M3, M81/M82, and M51—compare your views to earlier in the
month under darker skies. |
