Not many people post star clusters, by the way—everyone seems to want nebulae. Not long ago, I also photographed the Beehive and the Double Cluster in Perseus. Maybe I should post those.

Yes, I've noticed that open clusters don't get much attention. But it becomes clear why when you see who's shooting from which light pollution zone. As for me, I'm obsessed—I shoot everything I like) except planets, I don't have the setup for them and, most importantly, the seeing conditions.

And I also shoot whatever I like. I'm currently assembling a planetary setup and want to give it a try.

And what telescope is that for planets?

So that's a small thing for planets) you need a bigger aperture)

Well, you have to start somewhere, to get used to a different type of telescope. A friend also gave me a 2x Barlow lens. I’ll play around with it—Jupiter and Saturn definitely fit nicely, I checked in the app.

I want to try bright planetary nebulae like the Cat's Eye.

Of course, I had to try it. I tested it with a 150/750 reflector, but the seeing was poor.

The Cat's Eye is a very challenging target. I captured it, but only the outer regions came out.
