NGC 6992 Eastern Veil Nebula

Hello. I accidentally came across your astrophotography. To say I'm shocked would be an understatement. Some of the deep-sky photos in your album were taken with a Nikon D5100. The thing is, I have the same telescope as you and the same Nikon. I thought this camera was useless, but your work made me realize I was very mistaken about that. I would really like to know what settings you used on the camera? No matter how much I tried to set it up, I couldn't get it to work. In the end, I bought myself an astronomy camera. But still, the thought that I could also shoot with the Nikon won't leave me alone. Your Pleiades photo turned out amazing. I would be grateful if you could advise me on the Nikon D5100 settings. I'm also very interested in the coma corrector—where did you buy such a corrector and does it have any drawbacks in use?

Hello. The Nikon D5100 has a decent sensor, quite suitable for deep-sky imaging. The only downside is that it doesn’t pass hydrogen well due to the filter, but there are skilled people who remove it. The settings are shown in the photo. It just seems your mount might be a bit weak for long exposures, but it should handle around 30 seconds. I use ISO roughly from 200 to 800, depending on the target, with 320 being optimal. The corrector is a budget Chinese one from AliExpress—you can find it by name. In terms of quality, it’s passable with a beer :) It corrects coma fairly well, but stars get a bit bloated and some chromatic aberration appears. The main thing: get 30–50 km away from the city! Don’t even try in the city.
