Having a wonderful son-in-law who also owns a posh 3D printer is one of those life's little joys.  He is a clever, practical guy, who can turn his hands and brain to many of those DIY tasks from putting up shelving to constructing alcove cupboards. He also happens to be an electrics and IT tech wizard as well.  The family 'skills' pool rose significantly when he joined the clan. 

To date, using free download plans, he has printed me the following: 

• three tripod clips to hold power banks
• two vixen dovetail style clamp bases for my Zenithstar 61ii
• a pair of cable organisers for my ASIair Mini
• a green pen laser holder that can be attached onto a vixen dovetail style clamp

Makes simple astrophotography procedures so quicker. 

This green holder can now stay permanently on my green laser pen. I will replace the back two bolts in next couple of days for something similar to those at front. 

The plans called for tiny metal inserts but I found just tapping and threading the holes worked well 

The holder slots in place on the 3 D printed saddle clamp (black)

The whole set up is replacing my red dot finder - which I am finding difficult to use at times because it requires me bending down at very awkward angles. 

I am very aware that using a green pen laser is not without its problems and is a contenious issue - so this is a trial. 

The red ASIair cable organisers - a Godsend frankly

Three black tripod leg clamp bases with sticky velcro attached. 

I can then just push my power banks onto the legs (they have sticky velcro on back of them as well) 

I can even transport the tripod in the car with the power banks already attached 

Can we turn our astrophotography learning curve into structured tiers of learning?

Astrophotography ‘Experience Tiers’ with Integrated ‘Gear Ladders’

Learning astrophotography can feel a little like navigating the night sky without a star chart. You know there are incredible destinations out there - but it’s not always clear where you are, how far you’ve come, or which direction to head next.

As an educator of over forty years, I’ve long been fascinated by how people progress when learning new knowledge and skills. Recently, that curiosity has turned toward my own journey into astrophotography. In a previous post, “Is Astrophotography Hard?” (https://undersouthwestskies.blogspot.com/2026/01/discussion-is-astrophotography-hard.html ), I explored the common challenges beginners face when entering this exciting hobby and what the typical learning journey might look like, based on my own experiences.

In this post, I’d like to take that thinking a step further.

Is it possible to identify clear experience tiers in astrophotography—stages of learning that help beginners and intermediate astrophotographers understand where they are and what comes next?

Think of this as a learning ladder, or perhaps a series of stepping stones across a river. Each tier represents a combination of knowledge, skills, and equipment that can help us move forward with more confidence and less frustration.

In this article, I share:

• A proposed tiered structure based on astrophotography knowledge and practical skills
• How each learning tier might align with astrophotography gear choices that support progress within - or to - the next level

These ideas are very much exploratory. I’m starting from a few simple premises.

First, there is an extraordinary amount of high-quality astrophotography advice available - online, in books, and through local astronomy and photography clubs. Second, most of us learn reactively: we search for answers only when we hit a problem. Finally, Astrophotographers, by nature, are excellent problem-solvers.

However, these approaches can be haphazard. Without a clear sense of where we are now and where we want to go, it’s easy to feel overwhelmed or discouraged early on.

This is where progression-tier thinking comes in.

I should be clear: I still consider myself a beginner. Some of what follows may feel like educated guesswork. But this framework is my attempt to map out the astrophotography learning journey -from first exposure to growing confidence - so I can better understand my own next steps.

I warmly invite you to discuss, constructively critique, and contribute your own ideas in the comments at the end of the post. If we combine our perspectives, perhaps we can build a clearer roadmap for all beginners in the wider astrophotography community.

As always - clear skies, stay safe, and enjoy the wonder above.
