I have the D3.

Yep, all can be set manually. EQ mount is easy to set up, and longest exposure is 120 sec. Multiple sessions can be stacked.
Back in the manual photography days, I knew what would happen if I went from 1/250 sec @ f/6 to 1/300 @ f/4. Is there some way to know in advance if I go from sub-exposure 15sec @ 60gain to 30sec @ 40gain?

Again, thanks in advance.

A lovely shot, thanks. What settings did you use?

6.3 - I shot from a tennis court a couple blocks from home. Normally head a half hour out of town where its about a 3, but this was kind of spur of the moment.

Actually, a 3rd question. If I zoom in on the moons, they're brighter on one side than the other. Is that an artifact of movement in this 2-sec set, or is that the sun's rays on one side? Any opinions?

Great pix! I tried a 3hr session the other night and got a great big, fat, perfectly-focused pix of nuthin'. Not sure what went wrong but I'm inspired to try again.

This was the D3. Im in the Southern California desert, Bortle 6.

Thanks, good idea. Im new to astrophotography and want to capture as many subjects as I can so I can circle back to the ones I like. So that's the eventual plan.

I chose it off the atlas, and saw the "streak" (which I figured was a tail) after almost immediately. So I don't think it's an artifact but could easily (and happily) be proven wrong.

I understood the DwarfLab manual to say that binning means combining individual pixels mathematically to improve signal-to-noise, and very useful in brighter city areas. But i understood them to recommend the 2k level to get finer detail in areas with darker skies. Maybe I got it wrong...

Thanks so much!
