  1. To chime in here, I switched to APP for all my preprocessing (ie stacking) about 6 months ago and have not looked back! I still use PI for post-processing though. I had forced myself to learn PI's integration workflow and got quite good at it - DSS and PI's own batch preprocessing tool were too limited for me, I don't think I could rank subs by quality and so on. The full PI workflow was time consuming however as I had to sit at the computer for much of the process. And that's before image editing! APP is a joy - it's pretty intelligent in terms of loading the subs and can read the fits headers to put subs of the same filter together automatically. The individual preprocessing tabs are flexible - I can choose rejection algorithms, drizzle and crucially to me, how to rank the subs for stacking. Best of all I can just press "integrate" and go to bed! And wake up to all the integrations done by filter - the results look pretty good to me! APP is like an up-to-date Deep Sky Stacker which gives you some of the power of PI in your stacking. It's also pretty amazing at mosaics too!
  2. Thank you very much! In the processing I could have maybe done some more star reduction to help the claw stand out more, but I kept ending up with posterized stars, so I didn't try and force it. I like the result!
  3. Hi everyone, As part of the stretch of clear nights we had at the beginning of September, I went for these targets. I couldn't resist trying to capture both these objects in the same field of view, although the capture itself was affected by guiding and focus issues, not to mention the full moon. In terms of processing, I went for a "natural blend" narrowband colour mix here, though I may try a Hubble palette version of this in due course. The Lobster Claw Nebula, or Sharpless 157 (Sh2-157), is an emission nebula and, according to some sources, is between 8,000 and 17,000 light-years from Earth between the Cassiopeia and Cepheus constellations. There are several interesting features in the image, not least the Bubble Nebula, NGC 7635, a HII region emission nebula which lies 7,000-11,000 light-years from us and is a shell surrounding, and excited by, the star SAO 20575. Also in the frame are the Wolf-Rayet massive star WR 157, an open cluster of stars, NGC 7510 and the nebula NGC 7538, which is home to the largest yet discovered protostar, 300 times the size of our solar system. 14.2 hours of integration shot over two nights, WOZ73 + CEM25P + ASI1600 + Astrodon filters, 99% moon! Full details here Thanks for looking!
  4. Thank you very much...I feel like I've made a breakthrough with the colours in this image vs. my previous Hubble attempts!
  5. Thank you! I was very conscious of trying to avoid garishness... The Soul nebula is another example of a DSO that was not exactly top of my list to capture, but I'm very glad I did...there are some beautiful features within it.
  6. I now see this object in a new light...thank you for that!
  7. Thank you - I also generally prefer the more natural red palette, not least due to not having to tweak colours when processing...but I'm trying to force myself to get better at the old Hubble Palette!
  8. Amazing - congratulations! Rho reaching out to the Milky Way disc is one of the best things in the sky in my view. Love it!
  9. Hi everyone! Captured this data in one night from my back garden. My struggles with the Hubble Palette continue...on this occasion I went for the slight adjustment to hues in PI and then SCNR green approach and then tweaked curves from there....I think I made the colour adjustments too late in the process which put some noise back into the image...but colours are getting there. 6.8 hours of SHO integration, WOZ73 + CEM25P + ASI1600 + Astrodon filters. Full details here Thanks for looking!
  10. I am tired and have a sore throat but the show must go on! I'll go for pane 4 of my IC1318 mosaic which should have a cheeky crescent nebula in there...no windows mishaps tonight I hope...
  11. Well the night started off badly with a...Windows update on my scope mini PC! I kind of fobbed off some message when I last imaged last week, but last night the dreaded "restart now or in one hour" message came up...so I decided to bite the bullet and restart...and it cost me 50 minutes between 9.40pm and 10.30pm...I HATE losing imaging time. The thing is, I always used a travel router to remote into the PC, but really enjoyed connecting my rig to home WiFi recently and being able to control it from anywhere in the home... there's a downside to internet connections of course! The only consolation was that that period included the meridian flip for IC1318, so I probably lost more like 40 mins, or 7 NB subs when factoring in dithering. Anyway - all went okay around that rude interruption - left rig plugging away all night and got up early to cover it all up for tonight!
  12. Fast walk home from train, wolf down dinner, get out and move mount and OTA to optimal place in garden to shoot fast setting IC1318 all night, polar align with Sharpcap, find bright Western star to check focus and calibrate PHD2, slew to pane 1 and check orientation...then hit go at 9.31 when IC1318 has crossed the meridian!
  13. Well CO says 5 clear nights in a row coming up...there must be some mistake Shirley...I'm going all out for a Sadr mosaic! With the Cali nebula as my fallback target!
  14. Hi everyone, A couple of days after my previous capture of the Western Veil, the skies were clear again, so I had the opportunity to shoot the Eastern Veil and once again opted for bi-colour narrowband. In a sense, it's the shame the UK weather has been so unpredictable as I could have set up a 2-pane mosaic of the Veil, but doubting how many clear nights we would get in early September, I set up the framing of the Western Veil in a way which made a mosaic impractical...but I've ended up with two nicely framed individual images, so it's all good! As before, captured in APT, pre-processed in APP and post-processed in PixInsight. 3.9 hours of total integration using a William Optics Z73 on an iOptron CEM25P and captured with a ASI1600 MM Pro + Astrodon filters. Full details here Thanks for looking!
  15. Thank you very much! Yes that seems to be the consensus view - thanks for the feedback!
  16. Thank you very much! The Z73 has proved to be a pretty decent performer, I would agree.
  17. Thank you! I think what helped is that I shot this on a new moon night...the OIII data was really crisp....and of course Barry’s technique looks like it works for me!
  18. My first attempt at this beautiful part of the sky and was very happy to capture this data in one night. Another first was using Barry Wilson's "starless" processing technique for narrowband images - I hope I did the comprehensiveness of Barry's excellent tutorial justice with my attempt! I was really gunning for a wider field of this object to capture the rich filaments in and around it. 5.5 hours of integration using a William Optics Z73 on an iOptron CEM25P and captured with my trusty ASI1600 MM Pro + Astrodon filters. Captured in APT, pre-processed in APP and post-processed in PI. Full details here Thank you for looking!
  19. Thank you very much Olly! The previous iteration of this image had a darker background, but that also seemed to dim the immediate area around the galaxy too much...so I brought out the black point! I kind of agree with you, so it is probably a case of delicately adjusting the contrast with curves in PI (I'm a PI person). What I really struggle with is differing brightness levels when processing - it might look good on my laptop or computer screen, but then seem too light/dark when looking again on SGL or Astrobin or on an iPad. Feedback always appreciated!
  20. Thank you very much! I think integration time has been key for me...spending an extra night or two on the same object seems to make a lot difference
  21. Thank you all for the nice feedback so far! I am kind of torn between the crop and the full frame in terms of what I prefer, as you might have guessed...maybe leaning a bit more toward the full frame this morning!
  22. And here is the original field of view with my setup:
  23. Hi everyone! I've taken advantage of most of the clear nights recently, so after my recent M31, here is M33! This is my second capture of this beautiful spiral galaxy - last year's effort was one of my first with my mono camera...hopefully a year on, some improvement has been made in terms of capture skill and processing! Captured with APT, pre-processed with APP and post-processed with Pixinsight. This is a heavy crop of the original image, which I will look to include in the next post. 6.9 hours total integration time using William Optics Z73 atop a iOptron CEM25P and the ZWO ASI1600 MM Pro camera + Astrodon filters. Full details here Thank you for looking!
