Bit round about way of working it out but think it would work. Perhaps one of these M54 to T2 adapters then a T2 to T2 female connector then just use a T2 - 2” nosepiece. https://www.teleskop-express.de/shop/product_info.php/info/p8959_TS-Optics-T-Adapter-from-M54-to-T2-thread--male----photo-and-CCD-adapter.html https://www.firstlightoptics.com/zwo-accessories/zwo-t2-female-to-t2-female-11mm-extender-ring.html https://www.amazon.co.uk/gp/product/B07QFJ4F51/ref=ppx_yo_dt_b_asin_title_o08_s00?ie=UTF8&psc=1

The ball race fits between the two washers.

Found this little review of the Aldi spotting scope. “I have one that I bought some years ago, not sure if the current ones are similar. Based on mine though, if you have ever looked through a decent scope then you may find it frustrating to use (focusing was tricky) and the view is very dark and 'mushy', which didn't help, but that said for £25 it's actually quite surprising how usable it is in decent light (towards the low side of the zoom range at least!) and if you really only can afford £25 then it might be ok, though I rarely used mine and bought a good compact scope when I could afford it, which was like night and day in comparison! I took mine to Titchwell and struggled on the lagoon on a dingy day, the birds all blurred together into a mass of grey fuzz and when the RSPB volunteer let me look through his Swarovski (admittedly like comparing a trabant to a ferrari!) I realised how poor my scope was... I didn't use it again. I had been happy to use it in good light on my local reservoir before that though, you just have to realise that these things are only £25 and you can't expect to use them how you would with a more expensive scope - checking out birds at great distance or in low light is going to be very difficult and frustrating.“

Collimation Nightmare!!

And go lay down in a dark room afterwards. Baffling at first but will soon make sense. 👍🏻 -

I had the original WO Easytouch and changed it as I wanted slo mo controls. -
Sounds like the DOD collection point here. They collect first thing so if not dropped off the night before next day becomes two day.

Telescope Express does a tilt adjuster to fit. https://www.teleskop-express.de/shop/product_info.php/info/p4272_TS-Optics-M90-Tilting-Adapter-Flange-for-astrophotography.html -
Alt-Azimuth Balance
johninderby replied to Rob Sellent's topic in Getting Started Equipment Help and Advice
The. TS-AZ5 while It is essentially the same as the SkyTee has better quality control and both ends are threaded for a saddle. Mine has virtually zero backlash in either axis. No saddles supplied but the ones supplied with the Skytee are pretty poor.and really need replacing anyway. -

New focuser for Meade 127
johninderby replied to petevasey's topic in Discussions - Scopes / Whole setups
Used a now discontinued Baader adapter to connect to the OTA. pity they’ve stopped making it as it comes in very handy for a number of scopes. Was intending to fit this focuser to a Cassegrain scope but the drawtube was a bit too long so this ended up on Big Red and the Badder Steeltrack originaly fitted is now on the Cassegrain. Knobs are standard stuff bought from Amazon and eBay. Brass thunbscrews are getting harder to find now though. Just had to add nylon tips to the two large screws though. I built Big Red a few years ago using Carton optics. -
Which ZWO for solar H-a with longer focal lengths?

Borg accesories aren’t well stocked anywhere in Europe. FLO does sell some Borg stuff so maybe they could do a special order.? -

A Borg 7857 helical focuser doesn’t sag but not cheap. Not sure where you’d get one now though. Here's a setup I built for a PST mod a few years ago. -

I bought one of these focusers last week. Not bad at all for the price. Brass knobs fitted to match the scope and the chrome fine ficus knob replaced with a black one. -

Balancing ioptron RC 6”

Fitting a proper long dovetail saddle would give you room to move the scope forward more or oerhaps just a counterweight that fits on the scopes dovetail bar. https://www.firstlightoptics.com/counterweights/baader-dovetail-bar-levelling-counterweight.html -
Number 32 and cointing. 😁

Yes who would want that over the top and oversized bit of kit when you could have a handy little PST? 😂😂😂 -

Algonquin park onLy has one proper road running through it. Or did last time I camped there. There are plenty of fairly civilised accessable places near the road though. -
