Quote:Duncan ... That just may be the case. Since I won't get out to do polar aligning because in NW lower Michigan we get so many fronts coming off Lake Michigan, I may have to wait a few weeks for a cloudless night. I'm rather new to how Cloudy Nights has expanded. Can I ask how you came across my post? It seems there're are 1000s of threads these days.
Quote:Duncan...I've had one cloudless night since I added everything. I can't answer your question because of the weather. I used Precise Go-To to Capella. Everything I tried, the drift away from it could even be seen in Telrad Finder.

Quote:2+4 star calibration is not polar aligning. Once you finish your 2+4, slew to a stat near the meridian and Dec 0 and then hit the align button, then choose polar align, then follow tge directions. The 2+4 star calibration is a star model for the mount, not polar alignment.

Quote:Dave...I understand all of that and have done the 2 + 4 several times for various reasons. In the sequence of events that follows, one is prompted to polar align with the All-star Polar Alignment. I had tried drift alignment and Kochab method and others, but the Celestron method gave me the best results. What may be a problem on my mount is the knob which points down vertically (see photo) that determines latitude. I had to insert a piece of metal and glue it in order to get latitude correct because the knob and and screw were not long enough and use a pipe wrench to adjust. There is a guide which is not very accurate. Doing polar alignment watching the monitor in Maxim DL with 1 sec or less continuous exposures, I get the crosshairs dead on the alignment star, going back and forth with latitude knob and the horizontal logitude knob which work very easily. I did get 00-00-00 and tracking from then on was quite exceptional. My observatory is at 44 degrees; 81 min North latitude and 85 degrees 42 minutes West longitude.
Quote:Ed Thomas...I see what you're saying about moving the plate down. Anyway, I know I am reasonably well polar aligned. I did have SUCCESS TONIGHT! I took off some stuff and rebalanced everything. Then I went to utilities and went to factory settings. I had to enter all the info...state, city, time, etc. Then I did a 2+4 and a precise-go to M42. Dead on after hitting the go to star. In Maxim DL it tracked with no star drift for 60 sec. I tried to autosave, set image path in my flash drive, but then as I hit start, the error message came up "Cannot autosave sequence because of no sequence" or something like that. Never happened before. Remember I have a Starlight Xpress one-shot color M25C camera, so I don't autoguide.
