Cool. In the fall, I'll also be shooting with my Askar FRA500.

Perfect scale for a 500mm lens. I had to make a mosaic to fit it all in (560mm).

I'll be shooting with a reducer, which will give me 375mm, perfect for my 294 camera. I already have work done at the same focal length, but with a smaller tube. I'm expecting more from this tube)

Well, I finally shot it after a year =) I saw your comment on Irene's post. I'll get around to Andromeda soon. I'll practice my skills and then we'll do a collab. By the way, you've got the blue showing up too. I kinda thought that with modern, not-cheap APOs that shouldn't happen anymore)
