I agree like Williams Optics etc., these are not products to butcher!
Perhaps the main offender is the mass of the Rigal pulse illuminator - but I doubt you will bin that unit!
Since you have dismembered this beautiful object, suggest applying silicone grease (Dow Corning DC- 4 is the aviation version). Its a bit like Vasolene, but slicker and never dries out. MDS:

BTW this is the best electrical moisture barrier bar none!

Hmmm
, vaseline, now there's something I didn't think about.
I'll have a look locally to see if I can find anything similar David. There is hardly any weight in the illuminator, its lighter than those little metal ones that used to come with illuminated reticules. Very light.

I'll have a look into that Chris if I can't solve it simply. The focus thread on this though isn't all that fine, but definitely something to consider.

It does have excellent optics.

they really do have lovely optics John and the helical focuser makes it ideal for a guide scope. At least I'm getting plenty of ideas here. I'll start with the simplest and cheapest and then work my way up til I find something that works for me.
