Difference in Noise and field of view between an Astrocam and DSLR in the Andromeda Galaxy (Zoom in to see noise difference)

Watch the video covering the differences here: https://www.youtube.com/watch?v=zDiMulx4iaA - the video also covers IC1396, the Elephant's Trunk Nebula.

I used my Canon T2i for more than 10 years before I got myself a dedicated astro cam, the ZWO ASI533MC Pro. While I work on a full review of the astro cam, I thought I'd do a quick comparison between the two cameras of the field of view and the amount of noise. I think the comparison at 1:30 of the video is pretty cool since you can clearly see the difference in sensor size as well as the clear difference in noise between the two.

I often make astronomy videos on YouTube if anyone's interested: https://youtube.com/Naztronomy -

See this on Astrobin: https://www.astrobin.com/1iykiq/

Equipment used for M31:
* Astro-Tech AT60ED with the 0.8x Reducer/Flattener on Advanced VX Mount
* Mount controlled via Astroberry
* 533MC Pro image was separately processed and can be seen here: https://www.astrobin.com/gsroo6/
* T2i image was also separately processed and can be seen here: https://www.astrobin.com/twokix/
* Svbony 60mm guide scope with ZWO ASI120MM-Mini guide cam
* Stacked in AstroPixelProcess and did an auto stretch and exported.
* Post Processing: Only a slight contrast and saturation adjustment to highlight the differences. Did not do any kind of background extraction or noise removal.

Happy to answer any questions! Thanks for looking!

Can you do basic astronomy photos with a mirrorless camera? If yes, can you recommend me some brands under 1500$, please?

You can! I think the Sony Alpha a3000 is a popular option but I haven't used it so I can't give it a full recommendation.

I'd also recommend asking on a forum like CloudyNights and see what other people recommend. Best of luck!
