I still have 3 weeks to wait until it arrives... I have seen other model wich one end screws to the T-ring and the other end is a 2"end that goes in the 2" of the focuser ! But the one I bought is different and I don't understand how it fits on the scope or the T-ring.... Can someone explain to me how this fits ??? A picture or a drawing would be very cool... Thank you for helping me ! Maxx Edited by bouffetout (02/02/13 10:18 PM) Post Extras:       Raginar Carpal Tunnel Reged: 10/19/10 Loc: Rapid CIty, SD Re: Refractor field flattener ,how does it fit ?

Take a look at the spacing requirements from your CCD to the field flattener as well. For instance, I need 55mm of spacing between the CCD and my ATFF (I think?). So my ccd through the filter wheel results in about 26mm (I think) and I have to make up the remaining 29mm of spacing. I went searching on their website and couldn't find the directions for your particular field flattener; the one above it was listed at 55mm. So, maybe someone who has one can speak to it better than I can. Also, it sounds like it actually likes to be closer than that to prevent vignetting. Here is my new favorite toy for changing spacing: http://goo.gl/JTAUd It's basically a variable spacing ring. It comes in a 'short' version and a 'long' version. Hopefully that makes sense . Send me a PM if you need some more help. Post Extras:       Pages: 1 Previous   Index   Next   Threaded   Extra information 7 registered and 11 anonymous users are browsing this forum.
