  1. Managed to grab a couple of shots yesterday; SW Esprit ED80; Quark Chromosphere; ZWO 174MM. Stacked in AS3 and processed using IMPGG and PSE15 pc387
  2. Finally managed to process some images taken from 27th. Taken with SW esprit ED80; +Quark Chromosphere+ASI174MM (+/- 0.5x reducer) and processed using a combination of IMPGG and PSE 15. Hope to apply some of the recent IMPGG work flow posted recently, and finally managed to figure out flats to minimise burned out areas (applied to one of these images)
  3. Had some time in between working from home (ASI174MM +/- 0.5X reducer), Quark Chromosphere, SW Esprit ED80; processed using IMPG and PSE15). Does anyone have suggestions on how to control the bright overexposed regions in the images (Flats? or tilt adapter?). Also the colour palette in PSE is rather limiting and i can't get consistent colour renditions between images (the b+w versions have far more contrast and subtle detail) Help and advice would be appreciated Thanks pc387
  4. Ooop's forgot to mention I used a Quark Chromosphere. Thanks pc387
  5. Managed some solar imaging, after an 8 month hiatus. Taken using a ZWO174MM mono and SW Esprit ED80; Processed using AS3; impgg and photoshop elements 15. Need to sort out the bright overexposed regions. Pc387
  6. The Astrotrac 360 claims all night long tracking ability (at a price, and as yet not field tested by end users); not sure about unguided accuracy? pc387
  7. Just received this on my twitter feed from ATIK regarding the next gen Horizon https://www.atik-cameras.com/news/cmos-camera-horizonii/ pc387
  8. I used to use ImagesPlus by Mike Unsold, seems to have remained current and worked extremely well. Not sure why I stopped using it and switched to PI pc387
  9. I found this in the PI discussion forums, and do seem to recall there are minimum specs required for Starnet to run, older machines may not be supported PI module checks if it can run and won’t install if it can’t, the most common reason being that the cpu lacks the minimum set of vector instructions. pc387
  10. Here's a couple from Tuesday. Not much surface activity, but a couple of proms. Taken with ASI 174 mono, Quark Chromosphere+/- 0.5x reducer and SW Esprit ED80 I've stuck to monochrome rather than false colour; I find PSE doesn't always produce consistent results. pc387
  11. It Started clearing yesterday early evening, so I managed to get a couple of captures in between the white fluffy stuff. Not much surface detail, but some prom activity. Taken with a Quark Chromosphere and a Skywatcher Esprit ED80. Still limited in attempting to blend surface and prom captures with PSE. pc387
  12. Hi, The esprit has a focal length of 400 mm, and the 0.5x reduced image area looks very similar to the one in the FOV calculator. I need to add an additional spacer between the chip and reducer. I've attached a couple of images comparing reduced and native with the ZWO174MM ( I'm still learning and limited to PSE for combining proms and surface).
  13. I recently bought a ZWO ASI174MM for use with the SW Esprit ED80 and Quark Chromosphere; i can get full disc with a 0.5x reducer + spacer. pc387
  14. Hi Thanks for the comments and tips, I'll certainly look at re-mapping to sRGB when posting images in the future. As far as loss of Ha and SII colour, I'm not sure where this may have occurred. I usually end up with 2 saved TIFF versions (8 bit and 32 bit) in pixinsight. I use the 8 bit version in Photoshop Elements to carry out further tweaks before saving as JPEG and posting. pc387
  15. Here are 3 shots taken with my esprit ed80 and ATIK 460 taken on 10th; 14th and 15th Feb on a Paramount MyT mount . I left the mount running all night for the bubble and NGC7822, but despite the promise of clear nights over 50% of subs were ruined by clouds. Details are m42 Lumin; 30secs; 60 secs; 120 secs; 300 secs x10 followed by HDR composition in PI. 9x 300 secs each for RGB(1x1) Bubble; 16x H,O,S each by 600 secs 7822 8x H,O,S each by 600 secs Main processing was done in PI, followed by tweaks in PSE 15 (some selective actions in "Noels actions" for PSE). I Like to process all my shots ready for print (ADOBE RGB workspace) so always disappointed the way photo's appear on screen, since a print always appears to be more forgiving in terms of noise and colour rendition etc. All constructive criticism as to processing technique, workflows etc would be appreciated. pc387
