Got bored with Jupiter so here is a test shot...

[Astroman]

OKay taken with an unmodified toucam through a 4" newt.

I decided to see how deep I could go with a standard toucam on the table of scorpius. Got it down to mag 10.33 possibly a little lower, 10.5? OKay taken with an unmodified toucam through a 4" newt.

Two pics.. One of the actual image taken through the toucam (500 frames through registax) The other of skymap pro view. I did notice that skymap missed a star ....... Can anyone confirm the existance of the star from another program? it's arrowed, its next to the brighter star.

Nice shooting. The program has missed 2 other stars that you have captured also..

[Starkler]

What star catalogue is skymap using?

Or if you can give the RA and DEC I can try to find the same field in CDC.

[Astroman]

OKay here is all the info regarding the object and whatever maps skymap was using. Limiting magnitude was 11.
