My third night trying astrophotography and the first night without clouds. I am happy with how it came out, although I wish I had spent more time dialing in the focus as the stars are like Temu rgb lightstrips. I didnt get as much integration time as I wanted so I really had to stretch this to get a usable image. Absolutely looking for tips on improving. To save you some time though, the star tracker and Bahtinov Mask have already been ordered. I also realize my exposure was slightly to long per the 500 rule. 🙂

Imaging:
700 x 2sec lights
50x biases, darks, and flats
Bortle 5
Elevation: 105 meters

Stacked / processed with Siril
Denoised with GraXpert
Exported with GIMP

Gear:
Canon 90D
Canon EF Zoom lens 75-300mm at 200mm / f5.6
Joby Compact Tripod.

If your talking about the blue in the bottom, I did not feel very in control when trying to get the color to appear in the image. Is that something that can be solved with more exposures or is that purely a processing problem?

That is a gradient and can be removed through processing, with background extraction.

I extracted the background and stretched it. In the morning I'll grab the original file and try it again. I think I saw a button with 'gradient' in siril
