Always go for the minimum amount of rings and aim for a magnitude 2 star.

ok. If you were to get the image as seen in this pic, & you were to stick your finger over the end of the OTA you would see something similar to that black bar in the pic. Then you kinda run your finger around the circumfrence of the tube until it looks something like in the pic. You then run your eye along the OTA to find the closest primary screw corresponding with your finger. Now it's just a matter of finding out which way to turn that screw (trial & error) incriments of 1/16th

the iis past into eart shadow shortly after clearing the horizon.
and how nice venus and antares area looks.
my 5 yr old asked to turn her bed around to look out the window, right at venus and the red of antares.

Paul H, IIM ask a simple Q? It seems strange to me that you have to 'tweak' your collimation before each session. You have one of the best SCT's designed. Why is it nec. to re-collimate? They don't 'go out of coll', AFAIK. Something loose? I know you're doing high scale stuff, but it just seems a little............

jet stream non existant, should be a great night again.
i don't go out unless 9/10 seeing, which means i only go out 3/4 nights, It is not fair!
God must be punishing me for something!!!
Exagerating???
Only hassle is that at 5mm fl, the adjustment of the focus is soooooo sensitive and the image goes every where!, I have had my stepper motor controller fixed for weeks and still have not hooked it up for electronic focussing!
bad bad dave!
