  1. Mount Stops Slewing

    Shot in the dark: does the handset have a battery? /Jesper
  2. Looks superb and very innovative to me! /Jesper
  3. The future for mounts?

    Amazing how such wobbly and thin looking cogs can be so strong. Always wondered what an industrial robot would be capable of carrying a scope. It would be quite a sight. /Jesper
  4. Interesting thread. Did anyone run a CMOS with at least 5 or 10 min subs? Would amp glow or something else destroy the image? /Jesper
  5. Question from a CCD guy, why are CMOS files larger? Not just the added pixels? /Jesper
  6. Hi! I have looked through a telescope only a handful of times, using the dark hours exclusively to image. The scope back then was a SW120ED and the eyepieces cheap ones. Now I'm breaking up my imaging rig which leaves me with one or two APM LSOZ 105/650 to use for visual work. The questions that pop up are: - Is there a great difference looking through one scope vs looking through some kind of bino setup? - For the scopes above, what eyepiece could you recommend for Moon and which one for DSOs? I have no budget for a nice collection... I literally know nothing in this field of the hobby. /Jesper PS Perhaps better suited in the 'Getting started with observing'. Total newbie here...
  7. M31 (Esprit 150 core + ED 80)

    Absolutely stunning! Great colours! /Jesper
  8. Hm, 21.8 + about 15 = 36.8. About 18mm left. Might be some other OAG out there that you can squeeze in? With the stuff I use, M68 rotator and the Riccardi M63 reducer I'd be at about 74.5mm. 75.6 is recommended so I still have room for a stamp! OAG? Nope... but never used one. /Jesper
  9. Got a reply from Vince as well. The square threaded plate around the CCD window of the 16200 comes off and the EFW3 bolts on from inside the wheel housing. (I'd be willing to guess that one might drill holes in the EFW2 as well for this purpose). The back focus saving is about 5mm. Great stuff!! /Jesper
  10. 50.8mm, 50mm, 2" filters???

    Yes, odd mistake to do. In any case the Astrodon filters are listed as 50mm. /Jesper
  11. There were still some odd lines in there, and what looked like rotation. (as if the software tried to align the flat - well flats don't move...) /Jesper
  12. You can always add a fuse if you want to. I cut all my cig plugs and went for banana plugs or XLR plugs. /Jesper
  13. 50.8mm, 50mm, 2" filters???

    Yes indeed! I'm confused by the options here. Giving it another thought I realize that 2" is 50.08mm and not 50.8mm but that hasn't solved the mystery. All I ever used was 1" or 2" mounted filters. Gives me something to hold on to as I handle them... /Jesper
  14. I'm thinking about stepping up the filter size, but I'm at loss regarding the many different sizes around the 2" mark... The new Atik EFW3 comes with wheels in either 2" or 50.8mm according to FLO. To me that's pretty much the same dimension. Astrodon sell 50mm unmounted, so what version of this FW would I need? /Jesper
