Thankyou - more luck than expertise at this stage I assure you...

I agree with TJ you need to invest time into your autoguiding - its a good thing to experiment with when the moon is about

The doors to the treasure trove are swinging open now you've got guiding under way!
(can I hear a faint cash register sound in the distance too...?)
Thanks Rob - bear in mind that this was the best of about 20 frames - some of the others were seriously ordinary - didn't even get enough to stack. So there's lots of experimenting to come.

The doors to the treasure trove are opening, but they key seems to be stinking great wads of cash. On my short-term wishlist:

1. Better focuser. I am amazed that I got near focus at all as the standard SW focuser shifts the focus about a mile when you use the locking screw. Not to mention how it tilts the drawtube as well. would settle for WO focuser, but would prefer motorised moonlight....

2. Better (waaay better - 80mm triplet apo if I can get one) guidescope to replace the department store special currently in use - see pics below..

3. MPCC to stop your images making it look like you are zooming through hyperspace...

So thats at least $1500 as far as I can see - and don't even get me started on my longer-term wishlist.

As a PHD user who has still to get this whole thing going, I have a question for you: do you remember what durations PHD used when guiding?
Thanks!

The only thing I changed from default settings was the DEC algorithm - changed it to "Low Pass Filter" (and I don't even know why ), and the camera exposure - I think used 0.5s. Initially the DEC graph was all over the place which could have been alignment, balance, worm gear etc as I didn't check any of those things - just wanted to give it a whirl and check that all the bits talked to each other.
