    I compared Olly's 13mm Ethos to my 12T4 Nagler (under mediocre seeing conditions), and did not find the ethos a clear winner. Yes the FOV is wider, but the eye relief is clearly shorter, making it hard for me to see the entire FOV anyway. I can quite understand people going for Naglers. Great workhorses, and I much prefer working with multiple focal length to a single EP with the magnification of a short one and FOV of the longest. I find that changing exit pupil to optimize the visibility of a DSO is more important than how it is framed.

    Just to add the serial number of my 1995 GP-C8 (starbright coatings): 891881. An elderly scope heading for its third decade of use (bought in Amstelveen, 27 October 1995). It is a black tube with orange cover. Now equipped with 2" visual back and 14x70mm finder. I have just upgraded the mount to support dual axis drive and guiding port. This old scope is not going anywhere soon.

    Just had a quick play. Looks nice

    managed to grab some H-alpha data during lunch

      Look forward to a big mosaic later then. Back to infinite cloud again here today : (

    Doesn't that make you hungry at night (the last bit, that is)

      Clouds drifting in now. Still got 4 times the data I got last time. Now doing darks

  9. michael.h.f.wilkinson
    Sure, the last one. But I notice you have left a tempting space for more

    That's eyepieces anonymous for you
  12. michael.h.f.wilkinson
    The LZ seems great. It could potentially replace a fair chunk of glass in my case. It would make an ideal travel EP as well

    Forecast for clear skies tonight! Maybe I can image Lovejoy

      The forecast is also looking good for today and tonight. At last I have shaken this awful flu off so it will be a welcome change to get outside.

    Interesting comments on the MGs for binoviewing. I bought a pair of 24 mm MVs with future binoviewing or big binoculars in mind. I have a wide interocular distance 72 mm) so the diet might not be needed. But for guests it may well be.

    Observing Lovejoy with the APM 80

    Nice set of EP, but I assume you mean latest not last eyepiece (that's a very common typo in this thread )
  17. michael.h.f.wilkinson
    One problem with many zooms is lack of eye relief. The Hyperion is too tight for me for use with glasses. The Celestron might be OK(ish), at 15-18mm eye relief. I got a WO Zoom-II for its 18-19 mm eye relief. BTW, if you attach a DSLR to the zoom like this: that is eyepiece projection, not afocal imaging. Afocal imaging would involve using the camera lens (e.g. a standard lens) as well
  18. michael.h.f.wilkinson
    I understand it is meant for EP projection rather than afocal. It could be used for both, I suppose

      Nah, very nice Aussie fish. Cooked the filets yesterday. Made a nice stock from the head and bones today. Nicely reduced, and now in the freezer.

    clear sky predicted for tomorrow!

      Same forecast up here. :-) Fingers crossed.

    It sure is. Nine EPs actually looks quite modest compared to some set-ups. But of course the William Optics zoom and one MaxVision live permanently in the case of the LS35THA, and the other MaxVision 24 mm is on loan to the university's observatory (fits nicely between their LVW 42mm and a Hyperion 13 mm), until such day that I get either a binoviewer or some BIG binoculars which accept 1.25" EPs.

    So here is the new layout with the SLV added. It is the last one on the lowest row in the image.
  24. michael.h.f.wilkinson
    It is very unusual to spot one, and thirty of these flashes may require additional explanations.
  25. michael.h.f.wilkinson
    You get occasional flashes from sunlight reflecting off solar panels of (rotating) satellites, although you then also see the (fainter) trail of the satellite. I have seen two "point meteors", i.e. meteors coming straight at the observer. In both cases I could identify it as such because it was in the radiant point of a shower (the first was a Geminid, the second a Quadrantid).
