Skywatcher 130/650 Newt and Star Discovery mount $500
Having a bit of a clear out and selling my grab and go Skywatcher 130/650 OTA and Star Discovery mount. Looking for $250 for the OTA and $250 for the Mount but would rather sell as a package and will chuck in the Skywatcher WiFi adapter if anybody takes them both for $500. I would prefer pickup in the first instance and so will initially prioritise any offer where the buyer can collect. I have spotted the mirror with a Catseye Hotspot and done the milk jug washer thingy on the secondary. Thanks for looking. Oh, messages only thanks and cash or PayPal for payment. Advertised elsewhere.

Reason: Needs to go. Price reduced.
Just wondering what this "milk jug washer thingy of the secondary" is & does etc, to my understanding I assume you have made a plastic washer out of a Milk container, but would like to know where it has been placed in/on the 2ndry assembly and what purpose has it been applied for,, advantage if Im not mistaken,, ?
Also, how do you find or rate the effects of Color abberations, inparticular on planets considering being an F/5 reflector ?
Hi Bob, the plastic washers sit between the spider hub and secondary mount. The collimation screws bear against the plastic washers. It makes rotating the secondary a bit easier for collimation. Being a Newtonian there isn't really any false colour apart from what comes from the eyepiece. At F5 there is a bit of Coma. It's not the greatest planetary scope in the world obviously, I really use it for low and medium power views of bright nebulae and open clusters which it does pretty well.
Very good thnx Russel, and agree most smaller scope 2ndry's do suffer with rotation, and good to hear the Parabilizing of the main has been done reasonably well Also yes, quite a short F/L for planets, I used to have many scopes, but sold up a few yr ago now.
Atleast a 5mm ep on this for planets would betterra than a 350mm camera lens
Just thinking of a grab & go scope for socializing occasions
