Thank you - I will have a look. I could do with some inspiration from a fairly local source, rather than shots from the Canaries and such like.

I was in our local recycling shop today and they had this in what looked to be perfect order for what seemed a very good price.

I'd love to fit a motor to this but have no idea what model or motor I would need.
Any suggestions from the experts out there?
My plan is to fabricate a suitable mount for a DSLR on this.

I'll ask my David when he comes back home.

Looks like a decent set-up.

The value and need for a sturdy mounting is neglected by beginners far too often.

It seems reasonably OK - not high quality but serviceable, and for just over a score of the britons pounds, a good catch. It has detachable slowmo controls and looks like it has had a motor attached at some point giving the mounts have good use marks on.

Certainly weighs a bit - the mount is cast and weighs more than the legs.

It's obviously been home to a hefty scope in the past. Those tube rings suggest something like a 10 inch scope, which would weigh quite a lot at one end.

A bit of questioning of prof google suggests it is an entry level mount -  branded as the EQ3-1 from telescop-service, e.g.  https://www.teleskop-express.de/shop/product_info.php/info/p5546_TS-Optics-Beginner-Telescope-150-750-mm-with-mount-EQ3-1.html

It seems like there is a motor available  https://www.teleskop-express.de/shop/product_info.php/info/p673_TS-Optics-Optics-stepper-motor-drive-for-EQ3-1-mount.html so I may well give that a go but would like some confirmation from someone who actually knows what they are doing.

My David is not very impressed!

What's the tube ring diameter, roughly?

There again, you don't need a HUGE mounting if there's a relatively lightweight DSLR. HEe's gon upstairs now. I'll try and ask him more later.

About 140mm. Sure it isn't a gbp1k mount. Question is whether it is usable.

David, it does look like the EQ3-1 mount. A basic drive system for this would be similar to that which I recently purchased for my EQ3-2 mount. I can't find it on line at the moment but, there is an adaptor plate to mount a camera on an equatorial mount which costs  about £20 or so. One is on my list.

The tube clamps are 180mm internal diameter, so about an 8 inch scope. Not too shabby.

The mechanics all seem good so I will take a look at drive systems.

Consensus on t'interweb appears to be that the mount is OK, to a point[1], but the tripod is rubbish, especially for manual focusing. I would concur. I shall take a look at the mount and consider fabricating better legs if I do not have much joy with them. It may well be a case of adding suitable stiffeners, or replacing with something more robust as it looks like the tripod head is readily removable.

[1] That point is probably well within the intended use with a DSLR.

Saw a very bright object moving slowly W->E around 10:30 pm last night. Thought at first it was a plane with landing-lights on but it had no nav lights and was absolutely silent. It took about 10 minutes to traverse.

Any ideas?

Possibly.  I was thinking of one of these "artistic" satellites like the Humanity Star, but that took a dive back in March.

ETA: checked the NASA sight: ISS it wasn't.

The tripod is the weak point of many a mount. I suspect that the tripod illustrated would be serviceable under just the weight of a direct mount  dslr. Not that remedial action to make it stiffer won't help.

The tripod actually looks like the stock offering with many scopes. It appears to be the same as the one I got with my 150mm Newtonian from Skywatcher

It has the benefit that it is easily removable to attach a more solid foundation. I shall order the motor and think about how best to add a DSLR to the mount. Maybe drill a home and use a single bolt directly in the dovetail plate, or find a better camera mount.

Don't forget that if you are considering long exposure images, polar alignment will be important.

gives the brightest passes for Strasbourg, you'll need to correct/update for date. There don't seem to be any obvious candidates. ISS was the brightest thing, but about an hour earlier.

Yeah - must have been a plane after all, but very high if it was. Dunno why it was so bright, either.

Thanks for the site - useful.
