Hi guys & thanks for the welcome to the exclusive DSO photographic club

Can't afford to go any further at this stage so a better setup is not on the list at present. Thanks to Dave Pretorius for swapping cams with me temporarily (his has the mod & mine hasn't)

Geoff, my comments re the EQ5...I'm sure it's my inability to drift align properly thats the hold up I've been thinking & reading articles on the procedure & I think the penny has dropped now It also has got some wild PE going on I think. You can see the stars zig zagging across the preview screen as they drift across. (I assume this is PE I'm seeing anyway).

Tonight I'll try to get a better alignment happening & try to get the exposure times up a bit longer.

Piggybacking the toucam on the 9.25 it seems to be pretty tolerant of my alignment, but when it comes to shooting through the scope itself its a totally new ball game.

Heres 2 more pics (Beginner pics obviously )

The lagoon & orion. This is the minimum image scale I can achieve even with a 0.6 focal reducer using this webcam.

Check out the hot pixels on orion Is this the camera doing this?

Al, I read somewhere to use 100% gamma 50% gain 50% brightness but I'm not sure those are the best settings yet. I'll be doing a few experiments in this area.

Lagoon: My first attempt the other night. At that stage my alignment allowed me 3 sec. exposures tops! 20 stacked. 1 Dark subtracted.

Orion: 2nd attempt early this morning. 19X8 sec. exposures 4 darks stacked & subtracted.

Paul, thanks for the explanation frames versus signal to noise

OK! That big bright yellow thing in the sky is about to set!! ACTION STATIONS! ALL HANDS ON DECK !!
