  1. The Iris Nebula. 18 hours in total over several nights. Processing in PI. I used John Rista's NR techniques and applied some slight deconvolution. I also de-emphasised the stars using the method detailed by Adam Block. I processed the nebula separately using Starnet in PI an deliberately didn't over saturate the stars. Finally I went back and slightly darkened the background. Hope you like it, comments and criticism welcomed. https://astrob.in/b6esyw/B/
  2. Thanks, that's good info. I'll try it later on.
  3. Yes, sorry I missed it off my workflow. Edited now.
  4. You said you used mosaic/separate as the second step. You need to use register/match instead. I’m sure there’s an error in the light vortex workflow as I get the same geometry issue when I use seperate option. If you read Warren Keller’s book he used this method and it works every time. By the way, I also use APP for mosaic construction.
  5. I'm looking for some advice. I have never successfully created a mosaic of M31 that I am happy with. For some reason I can never quite match the intensity or the colours across the panels which you can see from the image below ( the Lum is usually ok). I'm not so worried about the seams as I know I can sort that but I do need help with the rest please. This year I made sure to take each filter on the same night. there is approx 1.5 hours of 300s in each RGB panel (x4) although i lost a when sifting them, and the Lum has 3hours in each panel My work flow is: 1. PI - Crop the edges 2. DBE each panel 3. Transfer to APP for mosaic construction - repeat for all RGB 4. DBE agan in PI 5. Register 6. Combine, background neutralisation, colour calibration 7. Noise reduction 8. Linear fit 9. Stretch Any advice would be appreciated - I've included both the stars and starless versions. Steve https://astrob.in/d5u2sd/0/
  6. Hi. I think it needs more than bearings. It’ll need a complete overhaul and gears looking at. I wouldn’t be comfortable selling it as advertised but would let it go for £125 at buyers risk. If not, I’m going to send it to Moonlite to be repaired properly. Definitely needs someone e who knows what they’re doing.
  7. Hi, I'd like to sell this as it is not being used. It needs new bearings so will need to be bought by someone with some technical know how (I have none unfortunately ). Open to reasonable offers (maybe around £200?) bearing in mind the original cost of the focuser (taking into account repairs etc). I use a Focus Cube now so it is completely surplus to requirements. https://www.firstlightoptics.com/moonlite-focusers/moonlite-cf-crayford-focuser-for-refractors.html Steve
  8. Hi, I am selling my Moravian. It is around 3 years old but performs flawlessly. It went back to Moravian for a sensor clean and maintenance last year so is working as new. It has a built in 5 pos filter wheel and comes with all original documentation and carry case. This s a great camera but I am looking to get into the world of OSC now otherwise I would not be selling it. I'm looking for around £1500. Pictures show the camera currently attached to my Esprit 100 in my observatory. Recent images can be viewed on my Astrobin page. Thanks for looking. Steve https://www.astrobin.com/users/steviemac500/
  9. Funnily enough it does on my phone too but the laptop is fine.
  10. This is a combination of 300s and 30s subs, combined using layer masks in PS. 300s - 72 L, 24 each in RGB, 30s - 160 L, 50 each in RGB. Processed in PI. Hope you like it, comments welcomed as always. Steve https://astrob.in/jq513s/E/
  11. Thanks Steve. My friend pointed me in the direction of a noise reduction tutorial which massively helped. I also used starnet to work on the stars separately this time.
  12. I've re-processed this with more of a focus on noise reduction and star colour. https://astrob.in/we1kpm/D/
