  1. I think it is more field curvature (EP not scope) than astigmatism, perhaps, looking back at my report here: http://stargazerslounge.com/topic/255999-morpheus-14mm-under-the-stars-finally-shoot-out-with-naglers/?hl=%2Bmorpheus+%2B14mm The Morpheus is nice, but not in XW/Delos league at the edge of the FOV at F/6
  2. I am not surprised you find the jump from a 17.3mm Delos to an 11mm a bit big. I always found the jump between the Naglers 17T4 and 12T4 a bit big (hence the purchase of a 14mm Morpheus. I am not sure that is a keeper, however. Decidedly softer at the edges at F/6 ( seagulls!). I haven't had a chance to use it in my SCT yet ( clouds!), where it might be OK. If not, the quest for a 14-15mm UWA with good eye relief continues
  3. Sunshine!

      Ja! Isn't it wonderful? And I've already put my scope out for tonight.

  4. Cheers guys! I actually forgot to add the C8 with solar filter, but then I do not use that that often anymore.
  5. Various configurations Coronado SolarMax-II 60mm + Double-Stack unit on Velbon carbon fibre tripod and Mini-Giro mount Lunt SUNoculars APM 80mm F/6 with Herschel wedge on home-made hardwood tripod and Mini-Giro APM 80mm F/6 with Solar Spectrum filter on GP mount Dual mounting of APM 80mm F/6 with Herschel wedge, and SolarMax-II 60 single stack
  6. Some of my best work to date on Jupiter was captured in February (C8, 2x TeleXtender and ASI120MC) And an animation
  7. This is a very difficult choice, as 2015 has been my best year in solar imaging to date, as exemplified by the comparison I made between the three H-alpha set-ups I have had: Left to right: LS35THa, SM-II 60mm and APM 80mm F/6 plus Solar Spectrum filter. Another obvious candidate must be the BIG animation I managed: 15 days of 30-odd pane mosaics Note: This is scaled down to keep the page loading fast; the big one is here (warning: 135MB) The million kilometre filament has to be in there: 2015 also so the addition of a Ca-K module to the kit. My best result is from December 28: Finally, one favourite must be this surge I captured:
  8. What's this? A scope cooling outside?

  9. Merry Xmas!

      Merry Christmas and a healthy and happy new year with lots of clear skies to you too !

  10. Nearly done processing 250GB of lunar data

  11. processing stack 64 out of 112

  12. Working on 115 lunar AVIs

  13. First duck paté in the oven, oxtail stock a simmering!

      Nice, I have just loaded mine with two Pork pies.

  14. Apparently the list has gone missing. We are looking into it
  15. Newest incarnation of one of my fracs: SolarMax-II 60mm with 60mm Double Stack unit I must say I agree with the comments on older Vixen mounts. My Great Polaris mount sits beautifully on its wooden tripod, and has worked perfectly for 20 years. Lovely piece of kit
  16. The long tube at the top is an assembly consisting of (from left to right) a 2" to T2 adapter, a Baader TZ-4 Tele-Centric 4x, a Meade variable projection unit (without 1.25" nosepiece or EP in it) acting as a variable T2 extension tube, the Solar Spectrum filter itself (the brass unit with the cooling fins at the top and a cable coming from it), and a Celestron 1.25" visual back. Below it on the left is the controller of the Solar Spectrum filter (temperature control), and below that is a power supply. The diagonal and EP are obvious, and to the lower right is the Beloptic Tri-band ERF in the cell made by Mark Townley.
  17. Not really strictly EP case, but is does contain one EP (Vixen 25mm Ortho): My Solar H-alpha case
  18. But that would stop the 200mm down to less than F/4, which defeats the purpose
  19. Ca-K data stacking away now!!

      I think you are making a lot of wallets nervous! Look forward to seeing your first haul. Can't wait to see results from the Calcium Quark too, will be interesting to see how they compare, you have a narrower bandwidth?

      First results are in. The Lunt Ca-K is rated at narrower than 2 Å. Not sure about the Ca-H Quark

  20. Ridiculous answer by the vendor. One of the very reasons to use refractors is their ease of use "out of the box" and lack of collimation issues compared to reflectors (as repeated frequently by Olly)
  21. Just celebrated 25 years with the University of Groningen

      25 jaar. Wow.

      Van harte gefeliciteerd!

      Congratulations!

      Well done Michael. :)

      Many congratulations, that's quite a landmark.
