How Many Galaxies In Origin's FOV?

[DFJones]

I've been putting my Celestron Origin to the test as a scientific research astrograph since July 2024. One of these studies asked the question "How many galaxies can I identify in Origin's 1.27° x 0.85° field of view (FOV)?" Naturally, I chose a galaxy-rich FOV centred on the edge-on NGC 891 galaxy in the constellation Andromeda. Of course, the number of galaxies I can see depends on my total integration time, which in this case is just 30 minutes with 10 second exposures. 

As you can see, I was able to identify 56 galaxies, but in fact could see many more. In addition to studying this FOV and others in detail, I may discover something new and important one day - you never know!

The number of galaxies you can see depends also on a quality of the sky which I assume is less or more excellent in your location. 

Thanks to the RASA optics your Celestron Origin looks like something between a 'cheap' smartscope and a proper astrophotography setup. It's no longer 50-80mm aperture. Very nice. 🙂

Usually Bortle 2-3 on our rural farm.

I think this is superb and i imagine very rewarding. Cool stuff @DFJones

What software are you using for finding objects?

[DFJones]

I use the online Aladin Sky Survey with the Digitized Sky Survey background selected, and also SkySafari 7 Pro app.

I wonder how does it compare to SetiAstro script.

He has it as standalone as well now so no need for Pixinsight.

How is the image from an Origin telescope observing? Would be better in the imaging or EAA section.
