I'm clearing out the shed and looking to deliver this to a new owner at the ASV Messier Star Party next weekend (Saturday 10th March at Heathcote). Pickup in central Victoria a bit of trek otherwise!
I bought this scope secondhand a few years ago but never got it into active service.
Bintel Product Page ($750) (https://www.bintel.com.au/product/bintel-bt250-f4-imaging-ota/)
James McHugh has a great post (https://deepspaceplace.com/at12in.php) about the steps required to optimise these budget scopes for quality imaging.
Scope has been fully flock lined on the inside and also on the top outside to prevent stray light in piggy-backed imaging.
There are two bolt holes in the tube ready for direct attachment of a guidescope (to reduce differential flexure).
The focuser has a crack (as I received it) as per the prediction in James' website above. It would be relatively straightforward to repair and reinforce the back of this plastic component which is easily removed.
$250 or best offer before the weekend :-)
If you're really serious about it I do also have the 3" ASA Wynne Corrector available, but would only sell that for close to its retail price.
