Looks like you’re making great progress!

 

I’m curious: how did loosening that declination brake knob go?

Are you also missing the knob from the focuser shaft? I can just see that part of the control box in two of the pictures you posted, and it looks like it’s been removed at some point.

I am purchasing a full ap 89mm solar filter. What is a good asking price for the 1.5” above, couple of pinholes blacked out?.

I am purchasing a full ap 89mm solar filter. What is a good asking price for the 1.5” above, couple of pinholes blacked out?. 

They're $265 new.  My starting rule of thumb for available items is half of new price.  Pinholes bad enough to need blackout would reduce that.  A nice-condition vintage version with synthetic panel might get a bit more because someone could swap in a better filter from a humdrum modern one.  I tend to think that anyone serious about solar with $100 will want a full aperture Baader, etc., and this would be to fill the slot for a complete kit and get little use.

I'd also suggest putting it on Ebay and seeing what it fetches.

The serialnumberless but flawless restore finds a home

 

the vinyl case is nicer than the bland and peelprone vinyl of my earlier late 90s standard. I paid too much for this case, $220,  both I and the seller thought it leather when the deal was struck. In any case it was the original part to the rest of the scope. Fair condition, brass brushy, several dings in the vinyl, but structurally sound. The post office added a ding by driving a forklift fork into the box, grazing the case!

 

That’s a Panoptic 19 of course, 68x, 140x.

So on the subject of cases, the seller rebated my half of shipping plus an adjustment to the admittedly minor shipping damage so I think I did okay. The two on the market recently around $150 were definitely challenged one with a broken lock, the other turned out to be my case that came with my late 90s Standard from Scope City! The stitching more primitive, the edges peeling up. I recognize my repair job, a series of tiny brass screws holding down the edges. I am going to hazard a guess this is an earlier perhaps 1st generation case. It did not have the extra pocket in back for the PG handbox. I cannot find that ad now, darn.

Answered my own question:

 

Ad 448120 over on AM is very similar case and brass screw repair I was sold along with a 1996 demo Questar Standard. The case in the ad came with a 1986 Questar. I think I got stung. The Questar did have a late 90s serial number on the base, and I happily owned it for two decades.

As for oculars I have been thru many Brandons, Brandon boxed sets including brass etc. For now I am horrors going modern lens design and single ocular Panoptic 19mm which at 68x squeezes out all the field and at 140x barlowed is going to reveal everything that can be seen. Another single solution is my favorite zoom, Baader 8-24mm for 50-150x, or the Baader turret with 4 classic Orthos.

Here’s what you get from Questar for a new baseplate. As expected ported for AC. I have seen sn 00000 ids, but this is featureless. $42 shipped, priceless.

That vinyl case with the ubiquitous peeling edge banding is late 1980s.

The plate included 4 screws. If I am to recreate the layout of the PGI I am going to buy a box. Know what they are?

Direct from Questar:

 

—replacement 1.5” solar filter element, $145, I decided to think about it

mainly for resale value, since I am testing a full aperture

 

—screws, it makes sense to get them from Q, other sources may not be identical, nor stainless

    BTW the baseplate screws and those that retain the 3 elements of the PGI are #4-40

 

—focuser knob $18.50

So what is the pinhole situation with brand new from the factory filters. Zero tolerance? Or is it something we live with even new? Do they typically accumulate over time? What are your experiences?

I suspect that a new filter element will not pay off in resale. Keep an eye out for a used one. I saw one for $100 listed last week.

Detectable pinholes don’t affect viewing. The ones that affect viewing are obvious, easily spotted and usually accompanied by other scratchy signs of abuse.

The factory admonishing never to clean suggests one can create them. I just cleaned a 7” one with care but with some firmness to remove stubborn stuff. Delicate. And only once.

I updated my previous post to reflect $145 for a 1.5” replacement element.

I saw $20 for a used one, presumably left over after an upgrade, likely pinhole riddled.

Has anyone tried the ES 20mm 68deg ocular as an alternative to the Panoptic 19mm?
