Who is imaging at F2 - 3 ?

I am currently on a RASA 8 @F2 and also have a old Boren Newtonian 8inch at F2.8

Nice to see you back!  Yes, I've just joined the F2 brigade with a RASA 8, all in conjunction with Paul Kummer.

Thanks Olly  Saw a post where you had a RASA8 too. Hope you have managed to sort out the image issues you had. You will love the RASA8, see my images in the DSO image section that I got in stupid fast time after a long time away from the hobby

What a charming spot!

I have a RASA8 which I optimistically mounted on top of my dual rig. I think the Mesu could cope (just) but keeping it aligned  with the aperture of the dome was a struggle so it goes on the mount now on it's own, when I can be persuaded to take the refractors off.

I was eyeing up a location in the garden for another observatory, but Mrs Tomato wants a summerhouse so that's been shelved. I might still put together a setup and take down rig, that would test how well the RASA holds it's collimation.

Possibly of interest to fast F ratio imagers since tilt isn't tolerated by steep light cones...

I'm not sure if this really counts but I am imaging at f2-f4 with the Samyang 135ED Lens

Sure it counts

Me too with the Samyang F2 but its normally working at f2.4. Usually doing close up at the same time with one of my other 3 scopes on the rig.
