That’s fantastic, but in the last frame there are heaps of "new" contacts that appear in the animation? Do you know what they are (no I am not talking about the dust thingy?)

Thanks all.
I am suprised at the Mag my system can reach. During dark of moon I intend to try for fainter.



Yes. The "flashing dots". I think they are cosmic ray(radiation) strikes. On deeper images I combine images so they are hidden by averaging/addition etc..
On single images they can not be hidden and as part of an animation appear to flash. The "dust thingy" is a ray that hit at an angle.

As I usually take only one dark for these images they can effect all in the sequence when subtracted. I am slowly building a master dark.

Stacking can rub out the fainter asteroids, brighter ones should combine into a series of dots or a short trail.
I always "blink" my images after processing and before stacking.
Having typed that, I have only ever seen one unexpected asteriod. Turns out my planetarium was a day out. The asteriod was known.:sadeyes::D
If you have kept your subs, you now have a great project for a cloudy night.;)


Thanks Fahim.
The 12" f5 and the ST-7e.
