Hi Everyone,
Not sure why these things aren't a standard on a GSO RC 10" OTA. But they are a must have if you wish to rule out any tilt in the system and would like precise collimation i.e. focuser unit aligned to OTA.
Bintel (http://www.bintel.com.au/Accessories/Collimation/Bintel-GSO-RCA-Focuser-Collimation-Ring/1729/productview.aspx) has started selling these recently for $119 which is a good deal.
I happen to have a spare one (purchased two units from Teleskop-Express and only needed one). The unit is a month old and never used and is up for sale. :D
The exact part is available here (http://www.teleskop-express.de/shop/product_info.php/language/en/info/p4043_TS-Kippvorrichtung-fuer-Feldjustage---Gewindeanschluss-M117x1.html) for 119 Euro.
Anyway to make the deal sweet I'm willing to sell this for $70 excluding postage. Sydney-siders pref and the item can be picked up locally.
Please PM me if you have more questions!
Regards
