    Long orthos and plossls don't give wide views, short orthos and plossls have painfully short eye relief

    I would have difficulties fitting a 31T5 Panzerfaust in my trouser pockets. If I stashed it in on of my coat pockets (or a photographer's vest) I would run the risk of doing some serious damage to parts of my anatomy if I made any sudden motions. A 1kg, HARD object dangling too close to groinal areas is asking for trouble,

    Lovely report Alan. Glad the clouds relented. The reason you never see a can of beans in photos of big Dobsonians is that the can is hiding in terror behind the giant scope (and even if it isn't hiding, it might just be one or two pixels in size ).

    Very nice addition. Quality glass requires quality whisky, just like qualty whisky needs quality glass

    Our youngest (11) cooked today, and he ate 4 plates of mussels. Very proud dad

      "...Buying bread from a man in Brussels

    I always hate it when manufacturers think they know better than me as a user what should be done under ceertain circumstances without letting you overrule their presets. As it is MY device I should be granted control if I desire it. I never like cameras (or computers for that matter) that do not let me do things the way I want them

    My main one is from Dörr. Not that cheap but big enough. My other case was a cheap secondhand one

    The T4s do not have 20mm ER across the board like Radian or Delos designs. The 22T4 has 19mm, but the 17T4 and the 12T4 both 17mm (with the 12T4 a touch tighter than the 17T4 in my experience). The Ethos 13mm at 15mm is borderline for me. I find 16mm works (and even the 15.6mm of the MaxVision 20mm 68 deg), but 15mm is just a bit short

    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

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

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

  17. 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

    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 )
  25. 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
