Svbony 70mm Mini Mak

[Toltec]

Finally got to try it out on a clear night, unfortunately the collimation was poor, flaring lines upwards from stars in focus. Sirius in focus had diffraction rings shifted mainly to the upper third and out of focus looked more like the rotor of a Wankel engine than a set of concentric rings. 

Already processed the return with Amazon. 

It was a warehouse deal so maybe that was why rather than just being a change of mind. 

Worked really well on a camera tripod with a fluid head so I'll definitely be looking for something to replace it. One of the other chaps at the local society has a 70mm Celestron which isn't much longer and gave very good views.

Great thread guys. After reading this I decided to order one. Should be here midweek. Just need to figure out the set up after I get it. Will try using it for high altitude plane spotting, grab and go astro and use with a DSLR also. Has anyone had any other upgrades to their set up since?

I customized mine with a finder scope.

Nice, fits on there nicely.

I’m about to build a mod for a daytime led reticle finder for angles use, based on a forum post, might help in this setup too. I’ll be attaching to a 127mm mak, so same sort of geometry.

OK, made a variation of a prism modded daytime red dot finder (mainly for daytime use). https://www.cloudynights.com/topic/854410-better-rdf-sighting-ergonomics-with-a-bed-glasses-prism/

Very cool!

Svbony makes nice product (I have the SV503 ED 80) but you might want to check the collimation, it might have drifted a bit when it got nicely banged around a few times on mail delivery ...

Here's how I did in the Celestron C70 (and my C90 as well) and it made a big difference in clarity :
