After months I have finally managed to achieve what I set out to do a long, long time ago in a.. well, this solar system actually because it's about my solar scope and the CG4. I purchased the CG4 (after a month of it being on back-order) with the intention of it being a stable platform for my Lunt LS60, the camera tripod and EQ1 being rather inadequate for the job (though EQ1 was a vast improvement over the camera tripod). I managed to purchase the wrong bar (ordered the losmandy by mistake), then found that I didn't have the appropriate bolts to attach the clamshell to the vixen. The final hurdle has been acquiring camera tripod bolts of the correct size and length, it took two attempts from an ebay seller (top quality bolts, mind you) to get ones that were exactly right for the Vixen dovetail bar and LS60 clamshell. I have to say that the CG4 performs brilliantly with the LS60, and they look great together in their white livery; it's like the two were made for one another. The blue Synta dovetail bar compliments the red part of the LS60, too. I look forward to trying the CG4 with a decent 80mm scope if I get one later in the year. Anyway, here are a couple of pics: That is the Hyperion 8 - 24 zoom, it works pretty well but the top end is sensitive to seeing conditions even during the day, I couldn't achieve focus today so stayed at the next stop down (12, I think). There is plenty of detail to be seen and appreciated at 12mm, focus is amazingly sharp. If I wanted to, I could probably slip in my 10mm X-Cel eyepiece, that is usually good for a close-up, though not quite as sharp as the Hyperion at 12. I do like it when twisting the pressure tuner knob to bring in the detail of the prominences, it's like they just appear out of the darkness, it has a good 'throttle' feel to it too. On the CG4 there is hardly any vibration, even when adjusting the pressure tuner knob (which requires a bit of effort). Touching the feather focus wheel doesn't even register. Very pleased with my set up, worth waiting for.

I'm having some success using setting circles on my cg4 mount with my omni xlt 120 refractor. By 'some success' I mean they get me in roughly the right place a lot of the time. If I've done a reasonable polar alignment how important is levelling the mount? I observe on my back garden lawn which is a bit uneven and the built in spirit level on the mount seems fairly crude.
