GM-8 question
A couple of questions and hopefully some recommendations from the group. It's been quite a while since I've had a scope for observing, but the bug has bitten again. Years ago, I had a Cave Astrola

Re: Recent 4" Tak Images from last weekend at ARGO
Hi Paul, I noticed that fuzzy as well and just assumed it was a galaxy. I checked the Digitized Sky Survey http://archive.stsci.edu/cgi-bin/dss_form?target=NGC+7331&resolver=SIMBAD and it shows the

Re: Recent 4" Tak Images from last weekend at ARGO
Greg, The delay after correction (usually about .8 seconds) is absolutely required. Until I did that, my corrections were always in the .5 to 1 pixel range. The mount was still responding to the prior

Re: Recent 4" Tak Images from last weekend at ARGO
Tom, +/- .2 pixels is excellent. Would you have obtained the same level of guiding accuracy ifyou had exposed the tracking CCD for say, 2 secs, without any delay? Greg Crawford

Re: Recent 4" Tak Images from last weekend at ARGO
Hi Tom, Very nice images. In the combo shot with 5905 at the center, there appears to be another, bright FFO (galaxy?) close to the bright star that is just to the left and above center of the frame.

Re: HGM-200 Stiction
Hi Gil, To get at the dual Roller Bearings inside the Dec. Assembly, you must first remove the Saddle Plate, which is held on by 4 Allen Cap Screws. (You may have to tap the allen wrench with a

Re: Sinking mount legs
Hey Bill, An easy fis would be to put a small square of plywood under the legs, when on soft ground, it should do the trick. CS Jay

Re: Sinking mount legs
Hi Bill, On my GM-8 I use celestron anti-vibration pads. But the G-11 has much larger legs, so you'd probably have to make something. It wouldn't be difficult, to cut some plywood into 4-5"

Re: Sinking mount legs
Hi Bill, There are small ground platforms (usually metal) available that are used in the world of surveying. These often have small spikes on their underside and are stamped firmly into the

Sinking mount legs
OK, enough of the teflon washer. I wonder if anyone has a solution to this problem. Over the course of an evening's observing, I notice that the front leg of my G11 starts sinking into the dirt

HGM 200 Stiction
List, As it turns out, the HGM 200 has the same stiction problem. I had the mount out for its shakedown cruise this last weekend in Chiefland, FL. The HGM 200 uses a large (~7") diameter nylon pad

HGM 200 & GoTo
Hi List, With all the talk about GoTo on the G-8 and G-11, I took a look at the Losmandy web page and found that only the G-8 and G-11 are specified for use with the GoTo system. Does anyone know if

Re: G11 stiction fix
Bill, I agree with you that the DEC axis will require more clutch force to hold the scope than does the RA axis because of it's orientation. I'm glad we now have this group to discuss our ideas
