I look forward to your images.

He is indeed. Last night he emailed me all of data on the specific scope as well as instructions for checking that it’s got through the shipping ok and for collimating. Its a unique scope so very happy to have all the measurements and diagrams in my hands.
He really is very good to work with.
I received some test images a couple of weeks ago when he was doing the shakedown before dispatch and it looks all good. Enough to check there is nothing of concern before shipping.
Skies look ok for a couple of days this week but let’s see how it goes.
“RCOS had a 250mm F7 at one stage. Fred on this site has one although not sure his may be F9??
I think 250mm F7 is a very good balance between speed of the optics and sharpness and aberrations. CDK settled on F6.8 and the cost of that is a bit of extra vignetting but good flats handles that mostly.”
Yeah. One of the reasons I moved the GSO RC10 on was that it was just a tad too large for the obsy if I wanted to piggy back another scope. I will have the advantage of the things you pointed out and the OTA is a bit smaller and also 20% lighter than the GSO.
It comes with a dedicated flattener and Catalin provided the appropriately sized adapters to the MMOAG.
I lose a bit on focal length, down from 2024 to 1790 using the flattener but it does means its a slightly better match for my local seeing conditions with an image scale of 1.06
I may or may not use the flattener. I’d like to see how it works natively given the STL6303 chip isn’t that big.
Cheers
