Custom built (Meade DS80) 80mm achromatic refractor (F/11) fitted with 2 inch rotatable crayford focuser (comes with 2 to 1.25 inch adapter) and Red Dot Finder Scope.

The focuser alone cost me $250. The views are really clear with only a tiny amount of false color on the very brightest of objects (moon, planets mag -1 above stars).

Optics are clean in good condition.

Excellent peformer on planets and binary stars (I cleanly split Antares and observed Antares B with a broadband filter). Also could barely make out E-F in Trapezium in Orion nebula on a very clear night). Nice contrasty views.

$200 for OTA, Focuser, 2-to-1.25 adapter, RDF - must sell to fund future telescope purchase.

Thanks,

Chris

Seems a bargain.

What brand is the Crayford?

I'm curious why you would put such an expensive Crayford on this scope?

How old is the scope? Yes, some pics would help.

Thanks

Hi thanks Matty and csb for your interest.

Attached are photos of the old girl. She was my second scope ;)- csb you ask a good question as to why I'd put such an expensive focuser on this scope - it may sound dept. store but the views are quite good - I tweaked that ota (remounted/realigned obj and squared the focuser using laser collimator and self made mylar aper.mask)

I got respectable performance out of it - was able to make out e f components of trapesium on a very steady night using averted vision... saw antares B with a filter and split many binaries.. and it goes well around 150x in city (or 200x on very clear nights /dark sky) on planets..

the focuser is antares (synta manuf). 2 inch rotatable crayford.

the diagonal is 2inch and I sanded the adapter tube back as seen in the photos - I know it looks horrifying but it stops the diagonal slipping out with your expensive dslr or ccd optics hopefully (the safety undercut doesn't always do it with this heavy diagonal but it offers up a nice wide field for large chip ccd)...

I must sell this fine little scope to make way for another scope purchase.

Please email for postage quotation.

Thanks,

Chris

Don't you check your email Chris? :) I emailed you at xxx and pm'ed you. Not to worry, I've decided against it anyway.
