I was guiding getting about 0.7 arcsec total (EQ6R) I naively expect that's OK-ish, am I mistaken? When I cull I'm quite strict now with eccentricity usually grading (WBPP) to about 1/2 to 2/3 (statistically) on that alone. FWHM and star count are the other criteria. I'm trying to keep the criteria simple enough to make obvious changes and see obvious results. I intend to progress to more sophisticated grading once I get my head around "things".
I think I may have a little bit of tilt still and have messed with it a bit. I got it to "better than it was" and will give it another go when I can find the energy to - so fiddly.
I definitely have major backlash in DEC and manage it with imbalance. One of the adjustment grub screws is seized and I don't want to snap it or the allen key (already bent an allen key). I've tried every penetrant I can find/concoct but I fear I'll have to disassemble the dec axis and give it a little kiss with a blow torch to get it loose. Not looking forward to that. |
The Dec and Ra worm carrier adjustment grub screws on the RQ6-R shouldn’t be that tight ?
Sounds like the grub screws are opposing or tensioning the worm carrier with each other ?
I have two of the these mounts at different sites and have adjusted my RA and Dec in both so Dec backlash is around 900ms to 1100ms. The grub screws on both mounts are easy to screw in or out as required
Here’s my procedure attached
Hope this info helps
