Hello I am new to the forum and new in astronomy. I recently aquired the now discontinued Astro Tech 65 MM Quadruplet refractor
have a few questions
What kind of focuser mask and solar filter can I use for it?
I noticed that the information says that barlows and long eye pieces cannot be used. I am wondering if there is an adaptor/attachment so they can be used.
I have a 2" star diagonal and t adapter for a Nikon D 7000 however I noticed that the telescope has no thread to be able to use these accessories. Any suggestions on how to go about them? or I must buy equipment for the Astro tech specifically and if so what I should get so I can use my nikon for astrophotography.
Thanks for your help

I have not used this scope, but I can try to give you some basic advice. This scope has a lens in the back of the scope, very near to where you put the eyepiece. So you do not want to put anything long into the back of the scope (long Barlow or eyepiece), or it will hit the lens. An adapter will probably not work. There are short Barlow-type lenses you can try -- you might try the TeleVue PowerMate lenses. They work like a barlow, but do not stick into the scope very far. There are other brands with similar lenses.

For the camera, you want to get a 2" camera adapter. One end will slide into the scope, and the other end has a T-thread and will thread into the "T adapter" you already have. It does not need to be Astro-Tech.
