Re: ES Losmandy G11 RA Backlash
hmm I don't see the calibration prior to the GA run, but it looks to me like you may have had an orthagonality problem there Towards the end of the log the long guiding runs look pretty good, you're

Re: ES Losmandy G11 RA Backlash
Brian, I wanted to share the screen so that you can have a better idea as to why I had chosen the numbers for guiding :D. I am attaching the phd2 log during which I ran the guide assistant. As for the

Re: ES Losmandy G11 RA Backlash
Hi Sunil Ah - i did not see a guiding assistant run there Screen captures aren't useful for analysis, if you can upload the log that included the GA run that would be great. Are you sure the log you

Mark, Your comment on Sunil having is clutches unlocked to transport got me to thinking. I transport my G-8 into the Mojave Desert for Bortle 1/2 imaging and never do anything to the clutches. Am I

Brian, All the values entered in the toolbar(except the Hysterisis) was recommeded by phd2. The one thing I gotta mention is that the weather here is a bit hazy so I was taking longer duration guide

Re: ES Losmandy G11 RA Backlash
Mark, Appreciate the responses. The truth is I have been battling this issue for the past 8 months when I couldn't use the mount at all. Before that it functioned well. Not this bad. To answer you

Re: ES Losmandy G11 RA Backlash
HI Sunil Here's my observations from your guidelog looking at your two longest runs 1. your settings are not very optimized for your conditions and equipment. your min move on RA is too high, it's at

Re: ES Losmandy G11 RA Backlash
Hi Sunil scope should be slightly heavy eastward and the guide rate should be less than 100%. That way the RA never reverses and hence backlash is a complete non-issue. Mark is spot on here, RA

Re: ES Losmandy G11 RA Backlash
Sunil, First reaction is that RA backlash should never matter when guiding: The scope should be slightly heavy eastward and the guide rate should be less than 100%. That way the RA never reverses and

ES Losmandy G11 RA Backlash
Hi, I own a ES Losmandy G11 Pmc8 variant of the Gemini2 system and I seem to have some serious RA backlash issues. I tried to get help in the ES Pmc8 forum but I was told to approach the Losmandy

Re: First time using PHD2
Just an update from my guiding experiments with PHD2 on Christmas Eve. I changed over to a ZWO 120 MM mini guide camera (and this calibrated quite quickly because it is USB3). By playing with the

Re: Degreaser / Cleaner..
I'll weigh in on saying mineral spirits as a general cleaner. Wear some chemical gloves so you don't strip your hands. Denatured Alcohol is a good rinse agent. Again, protect your hands, and a mask or

Re: Pointing Mount To Zenith To Take Flats
Hi Jim The Dec should be your latitude and the RA should be the current sidereal time, which is the current RA of the meridian. Do you have that available to you? Its a pretty simple calculation if

Re: Jupiter-Saturn conjunction sequence (GM-8)
I took my wife and kids to the "sandy hills" trails nearby to see this. We only brought binoculars and a dslr so there was no hope of a fantastic view or shot, but we had a lot of fun. Here's the shot
