That is properly fantastic, I will seriously look at that.
Well, after a million months I got my 11" v2, this is it set up in daylight before a 1st night's test, even still got the washing on the line :-) All balanced, all ready to go - I even got the celestron focus unit working with ASCOM and I must say - watching it autofocus (I use AstroArt for everything) is absolute MAGIC.
The lower picture is a quick test of 6 x 240 sec unguided of M101 reduced to 33% - I wouldn't call it first light either, the goal was to test the system. The slight pinch on the stars is the cabling from the Trius 814 which I need to sort out. I use a Starizona Filter Slider which is brilliant - I need to cut a hole in the side of my home made baffle to access it though.
This really was a test night - the Starizona Filter Slider, the celestron focus unit, the RASA itself are all new to me - after 15 years of using an Intes Micro MN86 this was not about getting a good image, but learning to to set the lot up, balance it correctly & all that jazz.
I think, by chance, that my choice of camera (Trius 814) with small pixels was lucky, it works very well with the optical dimensions of the scope too.
Bizarrely, in the UK we have had a mini heat wave - 2 weeks of 30-32 degrees (celsius), and at night time it just didn't cool down that much - that meant that the rig was continually changing focus, the stars were shimmery even though it was a clear night - it was actually quite rubbish, so I packed it in after one night as it was just not possible to take decent shots ( and the nights are too short).
Anyway, I now know how to set it up and what it's FoV is and I can't wait for longer nights.
I really like the box setup for the RASA and it definitely needs something like that, thanks for the link !
p.s. a FYI - I was told that I needed a retro knob in order to attach the celestron focussing unit - I got my supplier (FirstlightOptics - who were very helpfuL) to attach the focus unit and they didn't need the retro knob, so that is a bum steer from Celestron.
