Re: SM 60 II & III Tube Rings

Thats a good idea Mark ... I'm currently looking at the 80mm hinged pair as I know someone who

is selling a set to see if they are any larger ?

Thanks ... Brian

Re: SM 60 II & III Tube Rings

Hi Rainer

I have the non hinged Primaluce 80mm set and thought that each/either side of the rings would

equally take the extra small gap but the rings are too small and the OTA will not fit into one

or both of them at all even with felt removal .... which is a pity as they are superb !

SM 60 II & III Tube Rings

Hi Folks Does anyone know (apart from Meade) where I could obtain tube rings to fit an SM60 the diameter of the OTA is 81.5mm now I've looked into a couple of options and the primaluce Lab 80mm rings do not fit , the OTA appears to be a slightly awkward size so any help would be great , I may even b...

PST Etalon Adjustment PIN

Ah don’t know what I’ve done here ! But it’s one of those I wish I’d left alone ! I took of the rubber grip to expose the small screw and loosened it ... now the tilt will go a long way and won’t stop plus I can’t seem to be able to relocate the small screw into any location where it will take hold....

Re: Solarscope SF70DS incoming

I think that is a bit peculiar with regard to the solarscope in single stack ... I admit my only experience with them is in SS mode but here the view was perfect and all on band , of course the classic procedure is to tune the SS to most contrast before adding the DS unit , on a foot note I've reall...

Re: Daystar Scout 60 Image Problem

I didn't or hadn't realised that a solid etalon could de-contact

It's obviously always a risk with the much more fragile air spaced etalons

Nor I at least I'll be able to try its quark in other configurations

It is Mark and I don't normally but it's coming to that ... I think it's a good wee scope

and I just know there is more to be squeezed out of it , mobile quark ect

60mm SS ... Dark Image

Hi Folks I bought a used 60SS last Autumn and have quite liked it ... however I have found that it's only really usable with a 25-30mm EP & here the image becomes just bright enough but does display reasonably good surface detail , I read a lot now that many consider theirs to be too bright and of c...

Re: Daystar DS 60

Very interesting thread ... I've been thinking about removing the quark from my 60SS However mine displays quite a dark image compared to these , it does offer good surface detail when the seeing is ok ... the quark unit simply unscrews from the 80SS but would also require an adaptor of sorts.

Etalon info for beginners

Hi Folks

I have been asked for a link to info on etalons in general ... say air spaced v solid or just

a general understanding of bandwidths and how etalons operate.

If anyone can advise on some info on here then that would be great πŸ‘

Would be good for me to read as well 🌞

Thanks .... Brian
