  1. 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
  2. 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
  3. 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
  4. 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
  5. 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).
  6. 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
  7. 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
  8. 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
  9. Here's my effort from 2 nights ago under an increasingly rare clear and moonless night 1hr each of HA:OIII;SII using a Skywatcher esprit ED80 and ATIK 460 camera.
  10. Can't remember if i've ever posted a photo on this forum before; but here goes: I've tried to reconstruct this based on files obtained between 2014-2018,; never having the good fortune to chase this target for a full capture sequence overnight, the latest captures were last week under very windy and sometimes cloudy conditions. Details as follows HA; SII; OIII 6x600 secs each 2014 HA; SII;Oiii 6x900 secs each 2015 HA; SII; OIII 6x 900 secs each 2016 HA; Sii ;OIII 3x1200 secs 7_Dec_2018 HA:SII 4X1200 secs 13_Dec_2018 Camera ATIK 460 EX Mono; ATIKEFW2; Badder (H,O,S) 7; 8.5; 8.0 nm filters; Nikon 180mm f.2.8. Combination of SW NEQ6 and Paramount MyT. No Darks; Occassional Flats (as per learning curve over a 4year period) Processing; A bit of a challenge in Pixinsight, trying to use image integration and gradient merge mosaic pc387 simeis 147.tif
  11. That looks really nice (certainly not poor as an end/interim result), I'm sure there's some more colour that could be teased out? I was in the same boat as yourself, and there are some excellent tutorials by Harry Page, Light Vortex, You Tube etc that got be 10% proficient in a very powerful piece of software; but it covers 90% of my needs and worth every penny. pc387
  12. I think retailers with showrooms are a dying breed. There used to be Opticstar in the NW, but they went online several years ago. Green Witch North (Yorks) are no longer. Sometimes nothing feels so good as to touch and feel a prospective purchase, followed by an impulse buy; and a guilty feeling afterwards. pc387
  13. Hi, I downloaded the latest core software update from ATIK (August 01,, but having checked their website today, the earliest down load version is from December 2017. Does anyone know whether this is a mistake or a genuine reason to revert back a few version? There's been no response on the ATIK forum as yet. pc387
  14. Hi, I came across this "review/advertising" a while back on Ephotozine, which may be of use? https://www.ephotozine.com/article/photographing-the-night-sky-with-irix-lenses--32121 pc387
