I'm hoping to read more positive reports like yours. Round stars are good, using a filter is fine, it's an achromat.
I'd be interested in hearing how it does on a more difficult double like Zeta Orionis, 2.4" mag 1.9- 3.7. That was one that my 90 mm 48P struggled with.
How much did you pay? Even $300 is pretty good price considering the focuser and stuff. (The dew shield does not slide, right?)
At $229... That's tempting just to try it out.. I'm well fixed in 4 inch refractors but idiot Jon likes 4 inch refractors.

I payed $220.00 on a presale in late Nov. of the newly corrected version direct from SvBony. Couldn’t resist, since I was yearning for such a wide field with some reach, which I lacked.
The dew shield is a removable, tight fitting push/pull attached to the objective cell which screws onto the tube.
In my case, the objective was a bit over tightened in its cell resulting in triangular star shapes under close inspection. A little pinching going on. I relaxed the tightening to just beyond the first resistance and perfectly round stars were the result. Excellent collimation, which is good because there are no adjustment screws. I mentioned the focuser earlier.
So, as received a little tweaking was required to make it perform to its full potential.
I have not yet pushed it to beyond 119x, since it is not my intent to use it that way. I will give Zeta Orionis a shot tonight. The seeing is predicted to be middling at best but let’s see what it can do. I’ll start at 119x..
