Questions & Answers

Product Questions

weight? I was wondering what the weight was along with the 72mm Ed scope as well?
The description says that this can be used for white light observation. Does that mean solar viewing, and if so, what other items do you need, as I can't find an 80mm Etalon
I want to use this OTA on a iOptron Cube Pro mounted on a Vixen Porta mount tripod. Will this OTA be a good match for that mount and do you sell the Vixen dovetail plate I would need to mount it?
Can you give me the outside dimensions of the hard case for the 80mm please? Thanks.
Is the Vixen dovetail that is in the photo included? Also, what kind of finders will attach to the scope? Thanks, Martin
Please could you let me know the physical length of the OTA?
Would an 8 inches Vixen dovetail work for this scope or would it be too long?
