Skywatcher Dob questions
johninderby replied to ukskies's topic in Getting Started Equipment Help and Advice
Might replace the Bresser base with a nice OO style hardwood ply one someday but of course keeping the Bresser Alt bearings. π€π -

Iβve settled on the Bresser 10β for now. Still easy to carry around. Had a 16β Meade Lightbridge but it was a big heavy lump and a right pain to move about. In the end went to Moonshane.. -

A simple way on an OO dob is to bolt a Skywatcher dovetail bar onto the tube then use a small saddle with weights attached. -

It is possible to fit a GOTO system to an OO mount but not cheap. The StellarCat system is one option. Hereβs a lttle something I built a few years ago. -

Skywatcher Dob questions
johninderby replied to ukskies's topic in Getting Started Equipment Help and Advice
Think itβs the best commercial dob mount around. Very compact and strong, works very well and made of aluminium so no problems with rot if it gets wet. The Bresser is the second best with proper sized bearings but made with laminate covered mdf so not as durable as the OO The Skywatcher is the poorest of the three with a poor bearing setup that needs mods to work properly and the mdf doesnβt seem to hold up as well as the Bresser. -

The 1/10pv mirrors are really good and are the ones to go for. When the seeing is good they just have more contrast and are sharper. On nights of so so seeing you probably arenβt going to notice the difference over standard mirrors though.The standard mirrors are about the same as the Bresser. -

Ah just realised thatβs the 10β not the 12β -
Celestron C6 or 150mm Newtonian.

Having owned maks and SCTs and now a classical cassegrain I would say that the mak is slightly better than the SCT but not by much on lunar / planetary. However I find the classical cassegrain edges them both out. -

There is a fairly big step up in size when going from 10β to 12β. I think of 10β as being the biggest of the small scopes and the 12β as being the smallest of the big scopes if that makes any sense. Of course to some 8β is huge so until youβve actually seen one itβs a bit hard to visualise properly. My old OO 14β dob with my little old 10β Sywatcher. -

Should sit nicely on my photo tripod / geared head for a nice grabβnβgo setup. Only weighs 4.1kg and my photo mount will handle 8 or 9 kg. ππ» Little less grabβnβgo when on the AZ100 though. π -

johninderby replied to a topic in Discussions - Scopes / Whole setups
Right now at the offer price this looks like an alternative. https://www.teleskop-express.de/shop/product_info.php/language/en/info/p10748_TS-Optics-6--f-12-Cassegrain-Teleskop-154-1848-mm-OTA.html Focuser is poor though and needs upgrading which probably expains the sale price. Pity the focuser isnβt the same as the 8β version. Most refractor crayfords will fit. -

Had a 10β Flextube GOTO but replaced the flex tube with a solid tube which is actually about 1kg lighter. -

Up to a 10β dob is not a problem to transport in most cars. Base in the boot and tube across the back seat. The Skywatcher dobs have been popular for years but they do have their shortcomings. The standard focuser is rather poor and fitting a better quality dual speed focuser is very common. You will finds loads of mods to improve the movement of the scope. You should consider the Bresser dobs. At first glance look more expensive than the Skywatcher but you do get a lot more scope for the money and they already have a great focuser. proper bearings, use tube rings to mount the OTA which means you can move the tube up or down for balance and also rotate the tube to put the focuser in just the right position. Also has a rubberised anti reflection coating on the inside instead of the Skyliners thin coat of not so black paint. Also comes with a 6 point mirror cell on the 8β and a 9 point on the 10β that better support the mirror. Just a much higher spec scope. Used to recommend the Skyliners until I got my hands on a Bresser. However as the Bressers have only been fairly recently introduced they are very hard to find second hand wheras there are loads of Skyliner dobs on the second hand market. -
Yes like the way the series is developing. π You can tell some serious thought has gone into it and an excellent script as well. A quality production as befits someone like Patrick Stewart. Science fiction for adults. ππ»
