Thank You. Of course second option. I've made pencil drawings directly from eyepiece and than turned to painting at home. But it is hard to belive in real was much more detail. I could have this aperture just for M42 . It's so dramatic.

Telescope givs stunnig views because of high presision optics. Lambda 1/18 RMS is amazing result in f-3,75 mirror. Also build and finish is exelent. I couldn,t belive my friend made this by him self.
Max, you are wrong. Mirror's accuracy is 1/18L but it's PV on the surface not RMS. It's PV on wavefront is 1/9L. I know what mirrors I receive from my source

Sorry. Of course you are right. I didn't understand RMS correctly.
