[WITHDRAWN] Sky Rover 130mm F/5 astrograph refractor

[Atmos (Colin)]

Up for sale is my 5.1” F/5 APO astrograph. I mostly call it an astrograph because it isn’t really suited to visual use due to limited back focus. It’s a triplet refractor with a 3 element corrector built into the focuser. Cosmetically it is in very good condition with the only blemish I can find being a small paint chip on the dew shield caused from a knock on the EQ6 head within a fortnight of receiving it a few years ago.

Optically I can say it is an excellent performer but I can let the images speak for themselves. Here is two of my favourites:
Eagle Nebula
Eta Carina Nebula

What is included:
- Sky Rover 130mm F/5
- Sharp Sky Pro autofocus kit (has 4 programable dew strap ports)
- 5” dew strap

It’s a ready astrophotography kit, just add any DSLR and you’ll be popping out images
Looking for $5,000 for the lot.

I've heard these are good scopes. What's the reasonable image circle? Does this one have a fluorite element? And....what are you planning on getting next? You're not turncoating and getting a reflector astrograph are you?

[Atmos (Colin)]

The link to the Eta Carina image shows what it’s correction is like with a full frame sensor. It’s been suggested that it has a 55mm imaging circle which I think it could handle quite reasonably with a 16803 and it’d 9 micron pixels but you wouldn’t want pixels smaller than that on such a large sensor.
In essence, it’ll take whatever you throw at it

This model does use FPL-53 but it doesn’t contain natural fluorite.

I have already turn-coated and have a reflector Selling this as it hasn’t been used for a while. I had considered it as a headacheless DSLR setup but I don’t think I’ll ever end up using it for that purpose when the mount I use has to use a laptop anyway.

Oh something else I did forget to mention with it. A long time ago I ordered a very short back focus TS 1.25" 90º diagonal but it wasn't until it arrived that I realised that it had a M65ish thread and not a M68.
A few months back I had Joshua Bunn make a M68 to whatever thread the diagonal uses in the hopes that it would allow me to use the telescope visually.

I did manage one night to test it and it didn't quite reach focus with Meade 60HDs. It is close but missed it by that much; to quote Agent 86. Removal of the rotation ring or saving back the 1.25" barrel would allow it to all be used visually but this is more effort than I care to make.

So, this also comes with a 1.25" diagonal that almost works
