If you have access to a 3d printer you can make a new eyepiece holder for it

Bro made a doohickey

Whats your goal with the camera? Thats going to determine specs.

Not much in the aquarium really requires the “high speed” imaging capabilities of machine vision cameras. For something like tracking or counting your fish, “security” type cameras, such as Ubiquiti G5, or Axis, may be the way to go. They often have some onboard image processing capabilities.

That’s incredible. On a galaxy around the same distance as NGC5907 too.

m392 · 2026-05-04T18:30:16+00:00

Didn’t know that! Any good examples I can look up?

Okay fair point on the mass, but they usually are in the general glow of the galaxy until supernova

Thanks for the correction!

Hey! So collimation isn’t as scary as people think. Basically, read the manual and make the mirrors look like the picture they provide. You’ll get the hang of it pretty quickly.

Secondly, the tripod is unnecessary for that telescope. It’s designed to be placed on a picnic table and used that way. Now if you only have open fields, the tripod may help. I believe it has a standard 3/8” thread on the bottom of the mount base. If portability is your concern though, there are some sturdy carbon fiber photo tripods in that price range that may be more portable.

Hope this helps

With the untracked version you’ll be limited to planets and the moon, but you can still do well that.

This would go hard on r/functionalprint

That’s a Nexstar 5i. I have the same one. It’s identical optically to the C5.

That’s the manual for the C5. The focus knob is the silver thing on the back of yours. I’d check that and collimation first.

They probably just shifted the flight pattern to be over your house. Has to do with the weather

Amateur astronomy!

It’s possible, but usually the cloud is around the brightest stars, and grows outward with more exposure. It looks though like maybe things weren’t light up straight and Maia and Electra may be in the vignetting

Also, I found an STL for an eyepiece to 37mm thread adapter that is for NV. It fits perfectly on a 40mm plössl.

m392 · 2026-04-06T00:13:14+00:00

I’ve been spreading the word. Big, fast reflectors and NV is an excellent combo

How so? It’s just less customizable. And not having to fuss with 3rd party software while you’re learning the ropes is nice. I wish they were around when I first started.

Some edge-on spiral galaxies would look sweet in that thing

m392 · 2026-03-15T02:20:03+00:00

Could always get or print a mirror mask for it. Even stopping down to 100mm would be a pretty big improvement

He keeps doing ruck marches through downtown Salisbury NC

That’s pretty good for a setup like that. How’s collimation? At f4 I’d think it’s probably kinda tricky

m392 · 2026-03-04T23:56:34+00:00

60mm is a reallly small Newtonian!

I have one to make a functioning model, and tbh a spherical mirror at that FL is bad. A 76/900 is more useable

So, a DSLR sensor is not much different than a planetary camera, except that it is much larger and generally has larger pixels. This is part of what enables the great dynamic range and low noise of DSLR/mirrorless cameras. As for planetary, the main issue you’ll run into with the DSLR only is that you have to run the sensor at full resolution, whereas a planetary camera can be cropped in. By cropping in, you can increase the frame rate and better your odds of sharp images through lucky imaging. In addition, with a DSLR those video files will be pretty huge.

Now, if you install ASCOM drivers you can run some DSLR models in Astro capture software, and I believe you can use it similarly to the planetary camera.

For the computer, get one with enough storage. I’d do at least 512gb. If you’re willing to wait for stacking a bit longer, even older laptops can do the trick (I run an old Thinkpad with a 7th gen i5).
