  1. (edit - have belatedly noticed the new guidance above. Clear identification, upfront). I wonder if I have similar. NV is obviously a valid tool however, I would like it to be obviously differentiated from normal observing. Ideally a separate section however, as long the title of all NV posts begins with for example 'Night Vision report -' it would enable readers to delve in or immediately pass it by. No confusion. Have fun! Cheers Paul
  2. Selling my 18" Obsession dobsonian. Quality performer. Perfect height/size for observing. Goes deep into deep sky but... ...seemed to get too heavy to manage in/out of storage and transport, or was is the lure of a Takahashi TOA 150 APO... ...now also sold on. Cheers Paul
  3. 4s at f2, iso 1600 for the pic with Mercury, 6s for the one with the meteor in (later in the evening).
  4. Examples: Wind blowing from west, fire road running north to south. or wInd blowing from north west, fire road running south-west to north-east.
  5. Forestry Commission fire roads orthogonal to the wind direction. Limits the horizon though. Also, sounds quite freaky on your own... ...cheers Paul
  6. Tonight. Fortuitous meteor! A bit of map reading found a location with no light pollution to the west. Could do with a full frame DSLR and wider angle lens. Canon 7D MkII, Samyang 16mm f2. Hope it is apparent slanting up to the left towards Mars. Edit - earlier image added showing Mercury on the horizon.
  7. Two and a half minutes of astro Slow TV. Edited together a sequence of time lapse videos taken from Swaledale during the last month. New material taken last Sunday night. A bit of music by Lee Rosevere. Something to 'observe' if its cloudy where you are...cheers, Paul.
  8. Wee animation from output of stacking s/w. I like the effect. Cheers, Paul.
  9. Have recently done some readings for the Yorkshire Dales National Park. Separate nights have had 21.45 and 21.5 (averaged) in our garden. ?
  10. About 430 frames from the Orion time lapse topic. Orion, Hyades and Pleiades feature. StarStax... ...cheers Paul PS almost free of aircraft and satellites!
  11. 'Quick' edit of about 3 1/2 hours last night. Looks over some nearby cottages. One for a darkened room. Music by Lee Rosevere. 1270 frames. Canon 7D MkII, Samyang 16mm, Lightroom. Cheers Paul
  12. Obtained a sequence of readings last night. 23:10 21.26 00:30 21.32 01:10 21.41 01:50 21.45 These are each 5 readings after the meter has 'settled down'. Top and bottom discarded and remaining 3 averaged. Clearly demonstrate the darkening of the sky and possibly the 'loss' of Milky Way interference. Neat Incoming cloud stopped further measurements. Paul
  13. This sort of compositing is a definite no, no in my 'rule book'. Examples I've seen: - local landscapes (North Yorkshire) with the Milky Way taken from latitudes of southern Spain or the Canary Islands - a 'moonless' night with obvious strong shadows and a Milky Way that is never visible in that part of the sky and pasted L-R reversed... ...as long as you are honest with the viewers of your images, don't make false claims, you can do what you like. Compositing a foreground with a different exposure taken in the same session is fine, or possibly taken at another time if
  14. Known locally as the 'Three Sisters'. Have been faffing around trying to get decent composition
  15. See my SQM topic. Really pants early on, then... ...cheers Paul PS Good to get some in!
  16. The Yorkshire Dales NP and Nidderdale AONB are working towards IDA accreditation. We are undertaking measurement of sky bright/darkness. About 20:00 I went to out measure and found all the readings about 0.2 down on previous, around the 21.1 mark. The light domes were up and transprency was obviously down. Wind the clock forward to 04:25 this morning. The sky was CLEAR and DARK. SQM from my garden averaged 21.5, repeated 10 mins later. The moisture had been 'frozen' out of the sky, about-8C. This was an improvement of 0.2 on previous best taken in the early hours last year
  17. W-i-d-e field. Lined up along Swaledale this morning. Cheers Paul Canon 7D MkII Sigma 24mm 2s f2.8 iso800. Cropped in Lightroom etc.
  18. Well, my Xmas pressie was a battery grip for my camera. It enables much longer single take time lapse videos. Like this 3+ hour session. Free to air music by Lee Rosevere. Turn up the volume cheers Paul.
  19. Generated from the middle 3/4 of the time lapse sequence posted earlier. Convenient foreground illumination from a passing vehicle

  21. Basic edit. 1100 frames 5s f2 samyang 16mm Canon 7D MkII. Cropped and WB in Lightroom. About 04:00 - 07:00. Tired. Paul. Lunar Eclipse 2019

  23. I understand that Hawaii has an inversion layer, cloud/rain above which the observatories are located. Others may have more info. on this. You may need to go above it for clear skies. Paul
