Good point Bill, thanks Alignment stars should be separate in both RA and Dec, and should also avoid near the poles (i.e., don't align on polaris) wrote:

One thing worth mentioning regarding model building (especially for the first two alignments) is to avoid using stars that are close in hour angle. Here’s excerpt from the Gemini 1 Level 4 User

Mike, have you ever consider writing and publishing astro books? I think you would get a generous following...? Your the best Bro... Dale

Hi Vincent, I think I'm experiencing the same problem as you with my G11G, PEC shifts along the course of the night. Did you solve your problem ?? Best regards, Daniel

Mark, A C925 Edge HD is what I use, but I most often have it coupled with a 0.7X Celestron Focal Reducer for wider field as faster optics. While I have heard many reports of mirror flop with this

do a very careful PoleMaster alignment, but I never see any drift when viewing an object. That's great Mark. It helps when viewing, but as you pointed out, it doesn't really impact pointing accuracy,

PS—After getting good focus, I’ll lock the mirror next time; the EdgeHD has a pretty good mirror lock. Sent: Wednesday, August 17, 2022 11:01 AM To: [email protected] Subject: Re:

Brian, Thanks for this very thorough reply. I am very confident that the polar alignment is spot on. Not only do I do a very careful PoleMaster alignment, but I never see any drift when viewing an

I'm new to the G11G too.? I agree with your approach and with Brian's thoughts too.? Just sharing some personal nuances and hope you don't mind. If accurately polar aligned (within 30 arc

Sorry, one last comment! Someone early on mentioned you have to forget what you know about Celestron I don't use Celestron mounts, but i'm pretty sure Celestron has a "Sync" command that is equivalent

PS Mark, thanks for taking the time to outline your steps, that was helpful and really the only way to know how you were going about it [email protected]> wrote:

Hi David That is normal, please see the tutorial we have on doing polar alignment, you should be moving in one direction. There are other tips here as well:

Hi Mark I see a few problems with your approach, specifically the use of Sync instead of Align Here's my take on what should happen using your procedure, along with additional comments. SETUP - Cold

Hello My G11’s azimuth knobs have about 1/2 turn of free wheeling slack—- knobs turn with no resistence and no resulting AZ change. Can the mechanism be adjusted to remove this slack or is this

Mark do you have any non SCT scopes to test with at a similar 0.5 degree? FOV? I ask this so we can eliminate mirror shift or focuser shift which is common even in the EdgeHD scopes which is why I

I went through all of the suggestions made, and collected those that seemed might possibly be connected to my problem. Then I implemented them. Last night was a test. I carefully determined the CWD

That's a solidly good deal, I purchased similarly priced mint example of GM8 in that price range. The best deal I ever got was a minty GM8 with a lighted rocker switch Gemini 1 and LWT like maybe 7

Ken, Not sure how much of a difference in it makes but my LWT is the older style with push button adjustable lever handle type upper leg locks and came standard with the leg spreader limiter. I also

Thanks Chip, George - all good suggestions. Ken
