Good investigations by all you great folks. Yes, your remark about the needles able to shift to be angled to the 1.25 inch shaft....another fellow reported this had occurred in his (GM8?) mount year's

Mark, So you took the easy why out hey! :) The problem you describe may be attributable to the design of the needle bearings. The stock bearings are full complement Torrington. They do not necessarily

Michael, I actually have an older mount. There is no wiggle and the left hand bearing block mount hole. I did the spring loaded worm mods myself. For me the jury is out as to whether a SLW is better

I think your math is pretty close now. But the seeing is also a consideration. For exposures longer than a few seconds, most of the time seeing is going to make tracking accuracy below 1/4-1/2 arcsec

Thanks Les ! In the full mosaic I will crop a lot less vertically since there is a lot of nebula in the lower portion of the image on the other side but I liked this closer crop for this portion.

Nice! It looks like the equipment is working well for you, and I really like the composition. -Les

Stepping away from all the technical chat for just a moment here :) I bought the mount to make images and here is my first. It's just the beginning of the final image which will be a 2-panel mosaic of

Sorry about the bandwidth but to correct myself once more, the RMS of the pixels in the last paragraph is really the size of the image of a point source in pixels (I used a factor 2 between them

You have a poin

Hello I have discovered that under the gemini telescope set-up windows I can configure (port # and baud rate) a USB gps receiver and get data (tiem and position) Is there a way to feed directly the

One correction, the difference between MC and MM is additive not multiplicative.? So for an MC camera we have the MM number plus 2 or so, which is about 9.2.? The

I had the same problem with undersized RA shaft on my old G11. It really needed plating and re-grinding to the correct size, but an MI-250 came along and I took the easy option and sold the mount. The

resolution is cut in half leading to 7.2 arc seconds per pixel. For 1 arc second total RMS (keep in mind this is plus or minus which is a factor 2), a point source gets smeared out over 14.4 pixels. i

Guiding sub-arcsecond is not nearly sub-pixel in many cases.? For instance for my APS-C sized ASI2600MC and a 1380 mm FL Newt? I have norm([6249;4180])=7518 pixels on the diagonal for a FOV

My own G2 handset is working fine, but I often notice the "align LCD" message pop up during bootup. That message only lasts a brief time ..maybe a half second? How do you start the screen alignment

Peter, You made a list of gear elements that result in time-lag "hysteresis," but you left out one cause of DEC hysteresis on the newest SLW system's: It's the loose bottom mounting bolts, holding the

Alan, Interesting, this was not what Neal Barry said from his experience on this issue. It's no big deal to change out the bearings and/or shim the shaft, so we will see if you are correct on this. I

Yes, the shaft rattles, but that only has the saddle attached to it.? This does not affect the worm and ring gear engagement since that is set by a separate set of bearings that do not wriggle.?
