Re: Eastside Heavy Rule - How to Practically Apply Query
The primary reason (like 98%) is because I can do it MUCH sooner than I could with a camera.. I have a closeby ridge that blocks the Sun from hitting the scope early in the afternoon.. (17 deg in the

Awesome.. Thanks for explaining that, as I like to learn.. Now if can just answer the question I have (on a different topic) I'll be golden for awhile.. I'll tyr and find the answer online, but I

Re: Eastside Heavy Rule - How to Practically Apply Query
Why mess with an eyepiece at all. Just use your camera to begin with. I use a G11 (Gemini1) with a 10" SCT and 999 times out of a 1000 the object is in the FOV when I do a "goto". The FOV for my combo

Re: Used GM-8 Guiding Help
Derek, The worms use a miniature ball bearing because this type of bearing can be used to carry both radial and axial loads. Needle roller bearings are only really used to carry a radial load.

Re: Eastside Heavy Rule - How to Practically Apply Query
Yes.. Yes, sort of.. Being a (former) Carpenter, I use a tape measure and measure between the Toe Saver Washer on the end of the counterweight shaft and the bottom edge of the lower weight.. *but* I

East side weighting cord vs preloading both worm bearings...is there a difference?
Hi gang, Several really nice contributions have raised the question: How can one get better performance of the RA (that is, reduce periodic error and improve "unguided tracking" duration)? Many people

Re: Making the most of cloudy winter nights with a new mount and scope
Have you looked at the KStars/EKOS/INDI suite on the Mac?? EKOS has a polar alignment routine that I use (on Linux).? It is also the only astro capture software that I use.

Re: Eastside Heavy Rule - How to Practically Apply Query
I've always used the weight on a string 'trick' for my non-SLW G11 which always east-biases no matter where the scope is pointing.? Multiple references if you search past posts. Keith

Re: Eastside Heavy Rule - How to Practically Apply Query
Derek Thanks very much for replying and explaining your approach to this topic. Just checking I understand correctly - So when the counterweight shaft is on the eastside you slide the lower weight a

Re: Used GM-8 Guiding Help
Thanks for the history lesson Michael! Chip, wish I recognized that before pulling one apart, it's smoothness is slightly worse now, still better than my existing but I will be sure it goes in the Dec

Re: Used GM-8 Guiding Help
I meant "do they make needle bearings that could go in the (two piece) worm blocks".. Almost precisely because all the other bearings in the mount are needle bearings.. Derek _____ Sent: Friday,

Re: Used GM-8 Guiding Help
To answer...some history of the RA drive evolution... The earliest design uses 2 separate worm blocks, a short Oldham coupler, and the gearbox bolted to the mounting flange. It was recognized that the

Re: Used GM-8 Guiding Help
There are such things, called needle bearings. You have some in your Losmandy mount axes (that's the plural of axis, right?) wrote:

Re: Making the most of cloudy winter nights with a new mount and scope
There's only so much you can do without the sky. But you can admire and practice running your mount. Just don't mess with it. Don't take it apart to look at the parts. Don't think you can improve it,

Huh, you beat me to reply. If anybody read the description of the bearings on the McMaster Carr page for the bearings you would have read that the precision S.S. ABEC 5 and 7 bearings are caged. The
