I have a case for my Questar 700. Inside the top cover, there are three loops with snaps. See the attached photo. Does anyone know what these are for? I tried to put a desiccant canister there but it wouldn't fit.

 

Also, does anyone who has this case ever use the shoulder strap? The strap on mine broke. I never use it. It's long and very thin and rather poorly made. I want to get it repaired and make it more useful but I'm not sure what that would be. Maybe it could be turned into a short handle.

I don't know why this post appeared twice, but if a mod see this please delete the one without the photo.

Filters that attach at the rear of the lens.  I have six 700s (anyone want one?!) and have never seen such a filter in real life.

Thinking of when these were in introduced and in vogue, and knowing Questar, that area may have been for the little tiny folded instruction sheets that came with a filter that the user would have on the lens.

They would store the little folded instruction sheets in that space so they could refer to them while out in the field.

I used to have two. I bought the second one to compare against the first, which gave soft images. Do you see any difference in performance among the six?

 

I need to loosen the retaining ring that secures the corrector and see if it resolves some distortion in the diffraction pattern, but I need a clear night to take an image of a star first. I also see slight chromatic aberration in digital images when examined at very high magnification, probably due to the same cause.

Here are the two filters that screw into the back of the Q700. I was fortunate that they were included with mine.
