I have been told Planetary System Stacker is a solid piece of software but on my machine it isn't installing. Anyone with a Macbook Air M1 that has gotten it to run out here?

Install via Homebrew is not working. I get 

ERROR: Could not find a version that satisfies the requirement planetary-system-stacker (from versions: none)
ERROR: No matching distribution found for planetary-system-stacker

Running 
➜ ~ python --version

Python 2.7.18


➜ ~ python3 --version

Python 3.9.7

 
and 
➜  ~ brew -v

Homebrew 3.3.6
 
on the newest Monterey, Macbook Air M1.

By the looks of the error I would say Homebrew cannot find a suitable installer but I am not sure how that works.

Interesting looking dob theritz 

What aperture and focal ratio is it ?

It's a 1250/250=F5 telescope. 

Oh, and I forgot to mention that it is a very early Sumerian Optics. Some viewers might have guessed.

It's actually from the time Sumerian Optics wasn't born yet. It's the second one Michael made before he started manufacturing the fantastic Sumerian Optics collapsing dobsonians.

This is my pride and joy. For a few nights a year, though. Very happy with the portability. It's only 9.5kg's and it's quite small so I can actually take it with me as hand luggage on a plane! (never tried that out)

Mirror is also the best my money can buy: a OOUK research grade I think it is. 0.988 strehl or thereabouts. So the mirror is hardly ever the limiting factor 

My first M31. Made with a Meade 6" newtonian on a LXD75 mount.

I stacked about 20 lights of 23s each together with a bunch of darks. This one was made in 2010 so I don't remember the details.

Imaging was done with an unmodified Canon 350D. No filters.

Capturing was done with Nebulosity 2 and processing in CS5.

And here's M27, made the same way with about the same amount of lights and darks as I used for M31

I remade M27 in may last but I have not located that one. The color on M27 is much better because I used masking techniques which I was not able to use before (due to lack of skills )
