    Really misleading video.. 0:22 The back focus is wrong, it is way too large (71.5mm) it needs to be 55mm ... if you mount the camera like this. he is seriously out of balance. he leans back on the camera with full weight..when putting a vixen rail on it.. you cant rotate camera cause of focuser ...i dont know who build this but he or she dont know Sh,t about camera gear .. jeeeez

    I ordered one as soon as it was announced. This is precisely the type of telescope I was waiting for both in terms of performance and price. My sample should arrive some time next week, I cannot wait! I also heard rumors that there is an 85mm version of this telescope coming out as well. I am also looking forward to that one! If the price and optical performance are good, I am definitely buying it as well.

    How much equipment weight can the SQA55 focuser support? Would an ASI2600MM + filter wheel + Falcon rotator work without possible focuser play?

    • @chromafunk6194
      @chromafunk6194 หลายเดือนก่อน

      Its a helical focuser - the mechanics are internal. It doesn't use a focuser draw tube like most telescopes where it moves in/out from the back; no amount of weight added to the telescope is going to shift the focuser.

    @OldGirlPhotography หลายเดือนก่อน

    What an interesting concept: a telescope with a variable aperture? Use it as a telescope by night and a photography lens by day. The optics for both are a bit different (flat field needed for astro vs. more forgiving at the edges for daytime photography) and what about chromatic aberrations and vignetting - imaging looks really nice, I must say. Looking forward to seeing someone test this in the field. Really applaud Sharpstar for thinking out of the box.

    I have just received Askar D1 and D2 Filters. Motivated by your video. However, I am trying to follow the steps in your video, but your mouse moves so rapidly, that at times playback multiple time to figure out what you clocked on where. With you would have kept the mouse on what you clicking on. At around 8:58 you say "save the images just in case", but I can't figure out how did you say the 3 images, I could see your move move all over the screen ? Exactly what are you clicking on to save all 3 images ? At 9:17 you select ArcsinhStretch, after this I just could not follow what you doing as the mouse is going allover so rapidly, cannot make out what is being selected. Tried replaying 9:17 onwards repeatedly but now able to grab what is being done. At 14:29 are you clicking on the Execute Square at the bottom of LRGBCombination and then also on apply Globally, arrow went to both so cannot make our what was clicked on, both or only Globally.
