I made my own flange and bought an Antares adaptor from Agena Astro for my refractor. It took around 5 hours of drilling, filing and sanding to get it to fit. I used aluminium 12mm thick and a 6mm thick plate to make it all pretty. Also included a push pull adjustment. Much quicker than waiting for replies etc and cost next to nothing.
I will do a write up of the scope in the ATM section when it is finished...soon!
The focuser is a GSO Crayford from Andrews, which cost $129, a price that can't be beaten anywhere
Don't know how they do it for that price.
When this is finished I am doing a new focuser on my 70mm f7 refractor that has an awful plastic r+p... this involves taking out the objective and putting it in a new tube 100 mm diameter, big enough for a 2" Crayford focuser..more drilling, filing and sanding coming up.
