man that looks beautiful. There must be a lot of enjoyment just in owning such well made gear - and you get to use it as well.
Perfect scope for your cameras...particularly looking forward to seeing what it can do on galaxies with small pixels.

If you do name it that, I hope you don't have a stutter

Yes it should be very good.

I do play golf sometimes and I do have a driver that is called Big Bertha.
Hmm.

I think it should do quite well. Mike has shown how 300/F3.8 works well with small pixels. I used a Tak BRC250 and a FLI Microline 8300 a lot for galaxies and that worked very well together. That was 250mm and F5 1260mm focal length.

I just did a test with both of my cameras and they both came to focus on stars using the AP focuser and my imaging setup. I did not expect the Proline to make focus or at least I thought it was close or just going to miss so that is a bonus.
AP focuser 3.5 inch, MMOAG and adapters about 40mm total, FLI filter wheel 4/5 (20mm), FLI Proline 16803 (21.3mm) or SX Trius 694 (17mm).
Still I intend to fit a FLI Atlas as the critical focus zone is small and I could see that using only the microfocuser it would go from in focus to out of focus very quickly.
So it will be adapter to RHA backplate (approx. 40mm), FLI Atlas (31mm), MMOAG (35mm) +adapters (8mm), FLI CFW (20mm), FLI Proline (21.3) or SX Trius (17).
Alternatively:
Adapter RHA backplate to FLI Atlas (8mm) , FLI Atlas (31mm), adapter(4mm), SX AO unit and OAG (74mm), adapter (3mm) FLI CFW (20mm), SX Trius (17) or Proline (21.3mm).
RHA has 162mm of backfocus available from the backplate or 100mm from the AP 3.5 inch focuser (which is a beautifully made focuser with its stainless steel and feathertouch microfocuser).
The FLI Atlas has 10mm of travel so the adapters have to be accurately calculated so the Atlas winds up in focus at around half the travel available.

Thanks Andy. I'll try to live up to its capabilities.

Sure, but I didn't have a beautiful big 17" CDK on a PME at my disposal   buuuut if i did have both, man, I would probably be using the RHA for the beautiful wide clean 1.8 X 1.8 deg vistas it can deliver (and fast) under dark skies with the 16803

Good point Mike.
I think initially it'll be the one I have adapters for first!
What targets would be good at this time? I am thinking maybe a Rho mosaic.

Yeah Rho would be good I guess and hey, if it turns out ok, DM has awarded several dozen renditions of it (and Lambda Centaurus) over the years and even two different renditions in the same comp  ....
Having that sort of field at your disposal gives many options...besides given it is brand new equipment you now have a perfectly legitimate excuse to re-image some of the favourites again

A nice acquisition Greg. I reckon a rotator in the mix if you can fit it. It's going to make composition easier if you can fit it in the back focus.

I don't think there is room unless they are quite thin.
The adapter from the backplate to the focuser is about 45mm.
I can rotate the image train but it does require loosening set screws in the MMOAG.

Exciting! Looking forward to seeing the images that you catch with that fine instrument.
Definitely lots of cloud on the way... ;-)

Awesome scope Greg. I have been a big fan of the work you have produced with your prior scopes. I can't wait to see what you achieve with this baby.
