Hi John - I am looking for a DEC extension.

Jim, Not sure if you are just talking about an RA extension. I pulled these pieces out of my G11 when I put in the break-apart RA EXT kit. I am sure HGM still sells these. They are 4 7/8 in. in

Hi Brian, Yea that's how I view the logs, tonight started clear but after an hour or so I would get an occasional cloud drifting through the FOV. A clearer night would be nice but it still seems like

Nick just curious have you looked at these logs in PHD Log Viewer? they are pretty crazy, and shows a lot of lost guidestar problems and poor guidestar SNR

Update So I went ahead with the changes - enlarged the gearbox holes and aligned the shafts very well, worked with a much better polar alignment, adjusted worms to be on the looser side, they could

Liam, Keep in mind that G11 is the easiest mount for OnStep conversion. GM8 is a little more complex, but also not hard. Look for reverse worm design for GM8 on onstep forum, it seems to be the

Magnus, One possible source of the problem may be that your eastward weight bias is insufficient and your RA gears may be "floating" in a wind breeze or gust. I personally have found that the best way

Liam, I have both G11 and GM8. I use G11 with 10" RC @2000mm FL in my home observatory and it is great. On the other hand, I bought GM8 specifically for travel imaging due to its lower weight. I tried

Looks like you took this graph with PEC enabled and I don't think you will be seeing the expected frequencies in that case. Can you share the freq analysis without PEC and guiding?

That's the issue.? My 1/4-20 Cap Screws are?hardened steel and my hacksaw can't get through it.

If it's just a matter of the bolt lengths, just get longer stainless steel 1/4-20 bolts...(at least that's the threads on my GM8 DEC). If the bolts are too long, you cut them to the correct length

What’s the best way to raise the height of my ADM Dovetail Saddle? I would like more clearance between the saddle and the motors. I am currently using a 3” round 1/2" thick aluminum stock but the

I have lots of thoughts about your PHD2 settings.. Derek _____ Sent: Sunday, February 28, 2021 7:59 PM To: [email protected] Subject: Re: [Losmandy_users_io] Used GM-8 Guiding Help Update So I

All good ideas. The puzzle is this report: The worm blocks are loose and the worm must be loose. But the axis is sticking or the worm is sticking? This is a used mount, right? Maybe it's needle

Hi! I've recently upgraded my C8 to a C11, and accordingly, things started becoming problematic after that....? particularly my guiding. I have an older G11, with OPW on the RA axis. I normally have

I suggest you err on the side of looseness with the RA. at least you can rule out stiction then

Thanks Brian, The DEC was an odd adjustment this go around for some reason, even with the block pushed as far away as possible the worm seemed tighter than normal, but still rotated without much

Sorry to read that. I had the same experience in one G11 tucked motor system, and I gave up trying to get one of the gears off. I suggest you contact the factory for their guidance on this problem.

Michael, Looking at these set screws under high magnification, it does seem they are stripped internally and are no longer a perfect hex shape. I don't see a way to easily remove the gears without
