Great job Ving, the moon is a tad overexposed, but I don't know if your camera allows you to change the shutter speed.

The star shots seem to show a problem with your optics - notice how they're trailing off to one side (the upper right) a bit? It could be your collimation and/or pinched optics.

Have you checked both of these lately?

hi mike, yeah my colimation was off a tad. I just didnt bother fixing it... my bad :P
that moon shat was take with a moon filter on, iso set to 100 and aperture set to er... small. I dont have shutter speed control as its a really basic camera :)

hi geoff, my colimation was out and the seeing wasnt exactly great. I might give it a shot again soon tho. if i increase the contrast in the pic it splits :)

thanks for the coments peeps.

Nice one Ving :2thumbs:
The distorted star images may be caused by the optics in the digicam itself and/or combination of EP/digicam inbuilt lens - i have seen similar images of bright stars with my afocal setup CP 4500/WO 24mm EP/celestron 2X barlow thru superb optics newts - when visually it doesnt look that way at all.
