I bought this along with a TPO 2" to m42 adapter to use 2" filters with my Celestron C8 SCT and a DSLR camera. Works perfectly and is made of high quality material. I would recommend!

Strong and weighty, made with thick materials and coatings, plus it's nice to have brass compression rings. Fits my C8 and is a good idea if you're even thinking about taking photos through an SCT.

Works great on my Meade 8" SCT. Now I am able to use a 2" diagonal.

This adapter is sturdy, has two good sized thumb screws with a compression ring and allow me to use my 2” filters, using another use-specific adapter, with my sct and CMOs camera. Other adapter holds the filter and extensions and slides into this unit. Could not use filters in my setup without these adapters.

I bought the TPO visual back to attach my DSLR camera directly to the back of the scope. This allowed me to not use my heavy Crayford style focuser on my C-11 as my astrophotography set-up is nearly twice the suggested weight ratio for my CGEM mount. I am very pleased with this purchase.

Not a complicated piece of equipment. works well, made well.
