Hey Bros, i'm in a hurry, so here's that promised photo from NGC7000 (North America Nebula). Seond try, because my lens fogged in the humid air of the night.
Details: 200mm lens on a H-Alpha modified DSLR, 100x25 sec frames for the stars, 20x60 sec frames for the nebula.

Thanks a ton for the sMerit shower Cool

I was out last night to take another one, from a different region of the milky way, more zoomed out than the one i posted yesterday.
There were some thin clouds in the first half and distant lightnings illuminating (light-polluting) the sky in the second half of the session, but since i captured more than 4 hours worth of light data, it would be a waste to just move the files to the recycle bin (aka. /dev/null) before even trying to get a nice astrophoto out of them.
A dedicated astro camera plus filters would be delivering much finer resolutions, but i'll have to rip out my laser eyes ($100k, sure y'all remember) to be ready to spend so much money on a little piece of electronics in a housing as big as half a pepsi can.
Gonna take some time to regain lost sleep and backread the WO, right after grandmother-in-law's funeral has gone by this evening.
So much to do, so little time Roll Eyes

Good day!
And behave, will you, ChartBuddy?! Angry

What kind of costs are "we" (really you in this case) talking about. and what makes that kind of camera and set up different from the one(s) that you have been using? I would imagine that the more expensive set ups would have greater light gathering capabilities - so potentially BIGGER lenses.. but just BIGGER would not necessarily be better either.. I recall some of the ways that light is processed can have different kinds of set ups too... but you said that some of your cameras actually are able to move with their target while you are doing the slower shutter times..

Generally speaking, yes. Still there are some strengths of ccd astrocameras. They are cooled, so you don't need to take dozens of longtime exposure images of "black", to remove unwanted noise (by sensor heating and signal/noise ratio) in boring post-production hours. Resolution is about four times better, so much more details in finer structures in the image. There's more, but i'll spare it for today, i'm dead tired and here is my latest piece. Forgot the watermark, though.
