I find ABS is very good for a lot of my printing but no one filament is best for everything. Not all printers work with ABS though. I use Simplify3D. Not cheap but made a huge difference to my results compared to the free software. A useful guide here. https://3dinsider.com/pros-and-cons-3d-printing-filaments/ Printed with ABS.

Berlebach tipods may not be cheap but as they say you get what you pay for. So solid. ππ»ππ»ππ»

Replacing an ES 4.7mm that did give mr some floater problems. Used to have a 4mm Nirvana and much less of a problem with floaters so bought another one. Funny how some eyepieces suit some people better than others.

I sold the CC6β to help pay for the 125 APO but always regretted selling it and bought back the CC6β a bit later. I thought the 125 APO would completely replace the CC6β but it is much heavoer scope that requires a bigger mount so not very grabβnβgo. The CC6β will show more than the 127 mak but the mak is still a very nice scope and much lighter.

NEW StellaLyra Dobsonian Telescopes

I do wish mass market dobs would use marine ply for the base but suppose that would be too expensive. -

Got them from Glen when he used to run Lyra Optics. The Carton optics are now unavailable but still much sought after. -
You can get a simple L bracket that mounts the binoculars at the side but a better way is the TS L adaptor that mounts the binoculars on top of the mount and uses a counterweight.The width of the binoculars is no longer a problem. I used one on an AZ-GTi mount and it worked very well with a short scope or binoculars. https://www.teleskop-express.de/shop/product_info.php/language/en/info/p10777_TS-Optics-Adapter-Plate-for-alt-azimuth-Mounts-with-perfect-Weight-Compensation.html

Police called I hope. Some people are clueless idiots. Glad you escaped without any physical harm.

Canβt hear the mount slewing itβs so quiet. Need somewhere quieter to test.
-
Just tested the slewing loudness using a decibel meter but was quieter than the background noise in the conservatory which was 37.8dBA. In other words a housefly makes more noise than the mount slewing. π Decibels are a logarithmic scale not linear. 10dBA - Normal breathing 20dBA - Mosquito or rustling leaves 30dBA - A whisper 40dBA - Housefly or quiet room 50dBA - Normal conversation 60dBA - Laugher 70dBA - Vacuum cleaner or hairdryer 80dBA - City traffic 90dBA - Motorcycle or lawnmower

Yes you can use SkySafari to GOTO targets. Connects to SkySafari using Meade LX200 Classic settings Think it gets GPS from the phone / tablet Ppwer connector is a standard Meade 2.5mm 12v

Wonder what features the handset will have when it is eventualy released? π€
-
I think the software development will proceed as normal for these sort of things. Working out those few last bugs will take months. And of course even after itβs on sale there will be updates.
-
I was hoping to do some testing today but other things got in the way. π As Stu says just going from the starting position and aligning with SkySafari works rather well.ππ»

Big Red my homebuilt 100mm f/13 refractor using Japanese Carton optics. A magical scope on the planets and has seen off some very good 100mm APOs.- 38 replies

Televue Plossls have gone up in price recently (Β£93.00 to Β£235.00) so better bought second hand.

Get a decent laser like a Hotech and it will be spot on when it arrives. Cheap lasers do indeed normally need colimating themselves. You get what you pay for.

The f/15 has an OTA length of 125cm. They also do an f/12 version and Starbase does an f/10. -

I chose the Baader prism for my Scopetech 80. Prisms work best on longer focal length scopes. Scopetech and the Starbase scopes are both made by the company in Japan that makes the Starbase scopes for Takahashi. Classic scopes but with the latest optical coatings.ππ» -

The Nirvana eyepieces are a real best buy. Not quite as good as Naglers but not far off and a great price. https://www.firstlightoptics.com/ovl-eyepieces/ovl-nirvana-es-uwa-82-ultrawide-eyepieces.html
