For the record I attach the before and after image via
the Cheshire eyepiece with added circles.
I am now ready to take some pictures outside when the weather is clear.

I have done a safety tether string modification.

see pic.

I used part of a new shoe lace.

It's glued on at 2 spots just for extra security.

 

The lace could not be glued to the paint on the back of the mirror as

the glue would attach to the paint and silicone remnants and be easily ripped off.

It had to be glued directly to the glass.

I gently scraped off the paint with a fine chisel and used metho but

finished off with Acetone for a super clean surface.

I used 5 minute epoxy resin.

 

When I touched up some areas on the inside of the tube using a tiny brush -

with Krylon 1602 Ultra Flat Black they show up against the

TS "Black" anti-reflective paint.

Which is better?

The Krylon looks darker.

The next time the spider is out I might need to spray paint

as much of the inside of the tube as possible especially opposite the focuser.

 

cheers
