What's worrying you? I'm genuinely curious...
The Losmandy dovetail of the RC8 is held very securely in the saddle. There's no possibility of it falling out - I've tested it with a lot of force (carefully).
I'll probably add some counterweights in the future to keep the primary mirror centred over the declination axis.

I have these on my GSO RC8 and I have a lot less kit. You have the space available looking at your rig for at least one set which should help bring your scope back. |
Yep, I've seen them. Very handy. There is a benefit to having the scope sitting a bit forward: I can do an inverted pier flip a bit earlier, go to bed, and let the mount track for a long time without automation software.
The position of the scope hasn't caused me any problems that I'm aware of... but I'm very happy to be corrected or informed otherwise!

Thanks Greg. I saw your PDF for sale ad a while back, but it sold while I was still umming and aahing over it
The Atlas seems great but it's quite pricey - it would be the single most expensive component in the whole system, by quite a large margin, so perhaps overkill for now. The PDF seems to be the smallest/lightest focuser that I can find that will be able to handle the image train without sagging or flexing.
