What an interesting object! I've noted it down in my notebook for my shooting list. The star field is a bit distracting, but that's not a criticism. The integration is quite substantial—I'm curious what this object will look like from the Moscow region swamps...

Thank you! The stars dimmed, and there were even more of them. The Milky Way region — there are naturally many stars there. It will be interesting to see your version.
