Re: RA guiding awful after upgrade

Re: RA guiding awful after upgrade
Tom, i do see the jumps, but it's hard to see when or why they happen from a screen shot. Can you capture some autoguider logs (text) showing the position error, and corrections? Don't know if you can

Paul, I took a couple of screen shots of what is happening tonight.

Re: RA guiding awful after upgrade
Tom, how does the autoguider calibration look compared to before? Does it take RA and/or DEC more time to reverse direction? If dithering takes a lot longer now, I start suspecting increased backlash

Re: RA guiding awful after upgrade
John and Paul, Thank you for the replies.? Apparently I don't have notifications enabled so I just saw your messages. My balance is good and I do a new polar alignment and calibration every night

Hello, I was wondering if my recent question has been approved for the forum. Thanks, Tom

Re: RA guiding awful after upgrade
After making any mod like this you should do a new polar alignment, a new PEC curve (if you do that), and a new guiding steps calibration. Also make sure you are still balanced and redo carefully. The

Re: RA guiding awful after upgrade
Hi Tom, hard to tell what¡¯s changed in your setup, but I¡¯d at least check the balance in Dec and RA and make sure the additional hardware hasn¡¯t affected the worm/gear mesh. Regards, -Paul

RA guiding awful after upgrade
Hello, I bought an RA extension and 12" pier extension for my g11.? The goal was to improve meridian flips with my 130mm refractor. I checked all the screws in both components and they are

Re: GM8 alt/az adjustors
I don¡¯t have a lot of experience with mounts since I¡¯ve only owned two Losmandys so, I have no idea what a great adjustment system looks like or how they work ;). However, on both my mounts the

Re: GM8 alt/az adjustors
Thanks, Bill. Very helpful! The important point is that it sounds as if the GM8 adjustors are very workable, if not as good as my A-P 1200GTO (on which they are very good). Nothing can be as bad as

Re: GM8 alt/az adjustors
Greg, I will be a bit of a contrarian here. I find there is quite a bit of slop (backlash) in the adjusters. Others here have commented on it before so I don¡¯t think it is just me. When

Re: GM8 alt/az adjustors
The use of flat thrust bearings is really not needed, there should never be that much force on the lock knob/lever.? If you really feel compelled to mess with the adjustment locks a good cheap
Re: GM8 alt/az adjustors
Good data point, Michael. Thanks! It really sounds to me as if the GM8 might be among the best light (lighter?) weight non-strain wave mounts available today. You¡¯ve been around a long time, so
