  1. A decent malt whisky
  2. 1969 pieces - a nice touch
  3. Ian, thanks for that - explains a lot - I was using 20sec captures, but waiting 30s - 60s between captures - no wonder my stuff comes out jerky :-) Neil
  4. thanks guys - some useful tips there.
  5. Love the animations - lots of detail how do you get such smooth animations - is just down to the number of frames Thanks Neil
  6. Still got loads to learn, but managed to get my first proms. (Opticstar 127mm Apo, Quark Chromoshpere, 2" Baader 35nm H-Alpha filter as ERF, ASI1600MM-cool with an ROI of 1600x1200) Loads of questions:- i) better ways of masking off the overexposed solar disk? ii) How far should I push the expasoure for the prom iii) How to colourise - my first attempts are very red/orange iv) Hints and tips on how to make animations - number of frames, gap between exposures, how to get consistent processing between frames. All help gratefully recieved Thanks in advance Neil
  7. I've seen that sort of appearance when my Quark is off-band.
  8. I'm beginning to take it personally now. Yesterday - clear from 07:00 - 10:30, sun comes over my tree line @ 10;30 - 10/10th cloud; sun 'sets' behind tress 15:30 and by 16:00 its clear again until, about 20;00 when it goes cloudy. Same thing so far today, but maybe there's hope for clear skies tonight
  9. Here's the 35nm H-alpha spec:- http://astrograph.net/epages/www_astrograph_net.sf/en_GB/?ObjectID=8186716 and the UV/IR one:- http://www.baader-planetarium.com/en/baader-uvir-cut--l-filter.html look under the specification tab - passband is 420 - 680 maybe a bit more detail in the attached doc 2459210A.pdf
  10. Also - with a filter in the way - I also use the Baader UV/IR - you'll probably need to retune your Quark. An alternative suggested by Rupert at Astrogrpah is to use the Baader 35nm H-Alpha filter - I've just got one of those, so I'll keep you posted on any improvement or otherwise over the UV/IR - that is of course, when I get some sunshine. Regards Neil
  11. One other thing to try is to lower the COM port speed
  12. I'm hoping our cloud here on the south coast will just move westward
  13. All sorts of good stuff there
  14. @extremechaos, yes, just a gentle chat/hint - unfortunately, a couple of them are conifers over 60ft high - will cost a bit to shift, but if we discuss again will offer to share cost. Others are mature oaks, some of which are covered by protection orders.
  15. As soon as the Sun clears the tree line - at this time of year that's about 10:30 and allows me to continue until about 15:00. In the depths of winter I can only manage about 90mins observing time. Unfortunately, all the offending trees belong to neighbours and there's little hope of getting them 'removed' Neil
