  1. Will have another go and do just that! I was a little too excited with the new technique this time round. Have played a bit more with it now and will sort the levels properly. 😊👍
  2. Thanks Gary, it's definitely got me excited to try with other targets, as it opens up a lot of new possibilities for Dual and Tri-band filters with OSCs. I also had another shot at this with more emphasis on the Blue/Green Channel. I thought it might be good to merge it in with this version, so here goes... 🙂
  3. Thought I'd have a swipe at using AstroEd's nifty little Narrowband Recombination technique using Ha and OIII channel extracts from an l-eNhance filter capture of NGC1499 the California Nebula. The proper technique can be found here https://youtu.be/3HYwJNf5M4M, this is just my ham-fisted first attempt using what I had to hand. Will definitely be exploring this one for the future though as it's such an elegant solution. In this case, I have just created a Star Layer out of an already combined version and kept it to one side while I recombined starless Ha and OIII images and processed them before remerging the Star Layer. Be gentle with me but I kind of like the colours 🙂 Tony
  4. Added another two hours worth of 120 & 180s subs to the existing RGB data to bring us up to 4 hours. I think this has added some more detail all round and certainly seemed less noisy when processing. Happier with the colour mix in this one, the last one I did had a distinct green tinge to it looking at it now.

  5. Thought it would be worth having a swipe at this given the moonless night and the opportunity for a clear run for 3 hours or so from my balcony. 3.5 hours worth of 120s and 180s subs plus calibration. The Star Adventurer performed outstandingly, only lost 3 frames over the entire session.

  6. Reprocessed this as LRGB (with Ha as Luminence) and I think I prefer the detail and colour balance on this one?
  7. As I seem to be playing with colours this week, I thought it might be fun to have a play with merging two individual captures, one in HOO, the other in RGB. Both were captured with the WO Redcat and ASI294mc pro, one with an Optolong l-eNhance NB filter, the other with an Optolong l-Pro filter in RGB. I loaded both unprocessed Fits files into Astro Pixel Processor and did a little bit of cleanup work for light pollution on both before analysing the stars and registering them against each other. I then saved the registered images as .tif files and merged them in Photoshop at 50% transparency. I cropped the merged image and saved as a separate image before splitting it into starry and starless versions using starnet++ Subtracted the starry from the starless using Apply Image and cut and pasted the star layer into the starless image using linear dodge. I then went to town on the starless version, healing artefacts before playing with the details and colour mix using Camera Raw Filter. Then did a general cleanup using Noel's Action for noise reduction and local contrast enhancement. Reduced the star layer using Curves before merging the layer back into the overall image. Hasn't actually made a huge difference but has pulled out some of the fainter stuff and it's fun to play with colours 🙂
  8. Thanks Bryan! It took a little while to get the hang of things with the Star Adventurer but it is a very capable little tracker. The two things that make it all a lot easier are the William Optics Wedge and the ZWO ASIair Pro. The wedge is in a different league in terms of rigidity and ease of adjustment and this marries well with the ASIair’s great use of Polar Alignment, guiding and Plate Solving. The ASIair has been a bit of a game-changer for me, simplifying the hardware needs and enabling easier polar alignment and manual alignment using the plate solving. When I finally get my 80ED back out and mounted on something more substantial (sold the NEQ6 when I moved into the flat), I’m looking forward to using all of it’s capabilities. The SA has been my saviour during lockdown though, allowing me to capture and learn even from the limited view of my balcony.
  9. Reprocessed this 3 hour HOO capture as a false SHO. No real SII to speak of so I just duplicated the OIII extract. Merged RGB in Photoshop, stripped stars in starnet++ and processed starless image in PS using Camera Raw Filter and Selective Colour to bring out the colours (other than green 🙂). Merged with a reduced star layer and did a general cleanup. Quite like the portrait framing as it brings out the 'flame' aspects I think?

  10. Can't believe I've had two clear nights on the run! 3 hours worth of 120s subs under pretty oppressive light pollution from the Moon using Optolong l-eNhance filter. WO Redcat 51 ASI294mc pro at -10C unity gain (120) ASIair pro for capture and guiding Integrated in Ha-OIII Colour in AstroPixelProcessor Starless image via starnet++ Processed in Photoshop CC
  11. First attempt at playing with capturing with different filters in the same session. This was grabbed last night under fairly horrendous light conditions because of the rising Moon. An hour's worth of HOO and nearly two hour's worth of RGB using Optolong l-eNhance and L-Pro filters in the ZWO magnetic filter drawer. WO Redcat and ASI294mc pro on Star Adventurer Tracker. Stacked, Integrated and combined RGB and HOO using Astro Pixel Processor Separated star layer in starnet++ and processed in Photoshop CC Reduced stars and cropped for framing.
  12. 2 Hours worth but under a Full Moon. Will definitely have a go at this under better conditions. WO Redcat 51 on Star Adventurer using Optolong l-eNhance filter on ASI294mc pro camera. 57 x 120s subs at -10C at unity gain plus calibration Stacked in Astro Pixel Processor and processed using Starnet++ and Photoshop CC Cropped for posting.
  13. It was unreadable on my phone so I changed it to white. I’ve fallen victim to ‘theme’ again. Happens every time I paste text in. It’s a total lottery 😩
  14. I generally stand inside the flat before I kick off the main imaging but the balcony structure is pretty stable.
  15. It's also a very dinky little grab 'n' go rig. Here it is, in location on the balcony.
