Hello once again!! I'm ready to begin taking photos of the planets and deep sky and have a question or two. My telescope is a Ioptron 80mm. My camera is a Nikon D90. I just have the 18-55 lense, and the 55-200 lense, that came with it. My question is: do I need a t-ring, or a t-adapter to hook to camera up to the telescope? And are there any other accessories I need? Any advice you want to give is always greatly welcomed too! Thank You, Jon
I bought one of these adapters (with a clear filter) to keep the camera protected. When connecting it to the Canon I can hear/feel the locking pin getting engaged but to confirm the lock I turned the adapter as if to remove it and it just turns as if not locked in place at all. This of course is no good if the camera is mounted on a scope and a slight knock can dis-engage the camera so easily. Other t-rings I have lock in place as you would expect and have to have the dis-engae button pressed to allow you to twist & remove it. I have received a replacement but this is the same, it's not the same physical one as I have both at present and was due to send the original back if the new one was fine. Have dropped an email over to Baader but until I hear back I wondered if anyone else has had this issue. Steve
Hiya, a fews odds and ends that I never use: Revelation Astro 2.5x barlow (caps, but no box). Hardly every used: £25 posted (£34 new from Telescope house). – NOW SOLD. Revelation Astro 32mm ep. This was my favourite EP when I had a 5in reflector, doesn't get any use now. Perfect condition (caps, but no box): £20 posted (£28 from Telescope house) - NOW SOLD. Canon EOS camera adaptor and T-ring: £15 posted (UK) = NOW SOLD
On my Celestron EOS t-ring, the inside of the bayonet connection is threaded - i.e. the camera side. Anyone know what this is for? It's about 48mm diameter, female, couldn't say what the pitch is but it's finer than the t-adapter thread. Filter holder maybe? Or to use some other Celestron doodad? Or just anti-reflection ribbing?
I've bought a second hand Celestron Radial Guider OAG. It looks quite old, but is in good condition. I intend to use it with my C9.25, f6.7 focal reducer and Canon 600D dslr. I have a standard Celestron T-Adapter-SC #93633-A and Canon AF T-Ring. These fit together nicely and all is well. I just tried fitting the T-Ring to the Radial Guider OAG but they don't fit together. The thread appears different on the OAG to the standard T-adapter. I was wondering if anybody knew what I need to marry the two parts together? Or do I need to buy a different T-ring? Any help would be appreciated
