Hi William, Was your mount tracking OK before, or is this the first time you've used it in the obs? You say you managed to do a drift alignment - how sure are you it was good, if the stars continue

Hi, Is it true that Britney Spears is secretely testing a new AP 4800 Fork Mount? Wait til this hits the tabloids! Couldn't resist. Thanks, Rick wrote: in their to the with the issue. group, or

Well Rolando was right. My flip problem was caused by mirror shift. I had a 21' error in dec after a flip in a 20'x30' image. But, I also fould an error in my focal length setting in one program.

Joe, It's set to sidereal rate, I stated this in the post. That was the first thing I checked. William

William, Your CP2 is probably set to Lunar tracking rate - change it. Joe

Hello Everyone, I have an AP900 with GTOCP2 microcode D Keypad 4.12. The mount is in an observatory and I have done a star drift polar alignment but still have a problem with tracking. The mount

Thanks Bill and Jeff. OTA is can't On I'm

Thanks all for the opinions on the pier heights. I talked with Howard and them may be able to make one for me from a 42" tube. Thanks, Dean S

Dean, I opted for the 48-inch pier. I usually set the pier base on some pavers (for leveling), so that adds a couple of inches. I need to use a small step (about a foot tall) to get my 6-inch

Hello Harold, The filter is supposed to work in conjunction with the horizon limits that you can set (which are also available in v.4.12). I have not tried this out yet, but will do so the next
