    Thanks! I plan to add much more source expositions during this autumn, and assemble new resulting image. This one is quite noisy in 100% scale.

    Fantastic shot, one of the best M31's I've seen of late. I am absolutely hopeless at this target!

    I was wondering where are your photos lately on but now I know you are Pilgrim. Well, you have hell of a photos with pretty modest equipment (except TAL of course). Anyway, you should know that we Serbs LOVE Russian optics and we are totally crazy about TAL and Intes optics. I had great opportunity to watch through TAl 200K and Intes 180 micro and 65. Apo like telescopes. Your photos proves that.

    Beautiful shot! Great detail in the galaxy core. How did you blend the center shot in so well?

    Это просто чума!
    Даже не верится, что это не фото с Хаббла, а снято с Земли!
