First Two now Four

[theodog (Jeff)]

Hi All,
Managed to get 4 in the one field.
4x10min-L +dark 12"
Oh for a ST-8
Enjoy

[AlexN]

NICE!

great animation too...

[iceman (Mike)]

That's awesome Jeff, i've never seen 4 in one field before. Amazing work!

Well done.

[Matty P (Matt)]

Great stuff Jeff, that is amazing.

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?)

[edwardsdj (Doug)]

Very nice indeed.

[theodog (Jeff)]

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.

Gee well done. I guess I should try that with a dslr

another good image(s) , there must be heaps, out there, ive never noticed on my shots because of the stacking rubs them all out.

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.
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.
