  1. An excellent video Gav, very worthy of the praise in this thread and no doubt took may hours of hard work. Terrific 👍
  2. Hi Steve I have been meaning to experiment with planetary imaging for some time and your Jupiter images using your WO FLT132 have given me the final encouragement - thank you! I have just bought a second hand ZWO ASI224MC as a low cost/risk entry. I am now just contemplating the TV 2.5x or 5x powermate along with an ADC, perhaps the ZWO one. I am favouring the 2.5x as a more versatile tool along with being conscious of sky and scope limits. From your experience which would you recommend? CS! Barry
  3. Your latest revision Rodd is very good, with some fine detail in the Ha jets emerging. Well done, good job! CS!
  4. Excellent Ian and I am so glad my new-ish tutorials are helping you gain confidence with PixInsight: it can only ever be a benefit to have processing options at your finger tips. I have more tutorials planned, one in progress - it is simply down to time at the keyboard and all of the other competing demands on one's time. CS!
  5. Congratulations Peter on a detailed image celebrating your first light ?, lots of delicate Ha jets evident along with the faint arc. I am looking forward to more images as you hoover up the photons.
  6. Great image Sam and not easy from busy urban skies ?.
  7. Very well done indeed Gav. Great capture and processing skills for the faint outer ring of stars. This really is a difficult target and you have executed it with aplomb ?. Your enthusiasm for our hobby shines through yoour write up and I am so pleased that the Mesu is performing for you.
  8. A really excellent image Maurice. I saw the same faint dust in a recent M64 I have imaged from home however did not have the best luminance or RGB data to lift it from the noise. The faint blue is there and you have the tiny detail in the core. Well done on a top image.
  9. Lovely result Olly. Very helpful timing to see your benchmark image as Steve and I have data on this target and hope to finish soon. Your idea of collecting Ha is sound too: a screenshot of a raw uncalibrated single 1200s is attached to whet your appetite. The Ha will really help lift the active HII regions. Overall Olly a really impressive image from the new dual setup.
  10. Very impressive result Ciaran and great write up - perseverance and 'rule' breaking can indeed pay dividends ?.
  11. Excellent image Olly and congratulations on your new double rig. Who'd have thought you had a spare TEC140 lying around? I am looking forward to seeing the emergence of some grand and deep projects ?.
  12. Very good image Ciaran - flat background, star colours, rich dust, focus. Very well accomplished.
  13. Lovely image Ola - delicate and confident processing.
  14. Lovely wide field and surprisingly deailed view of the Rosette. Very sharp optics on the Canon lens too. I agree that for this target there is always room for one more ?.
  15. Thanks Goran. Versions B and D on Astrobin are rotated 90 degrees. In this orientation Gamma Cas is at the ‘top’ of the vertical frame and the Ha sweeps around the star in an arc ?.
  16. Cheers David . . . the dark skies at e-Eye really do help with the faint stuff.
  17. Thanks Gav. In this instance the two channels were kept and applied separately. I have and do produce a blend of Lum and Ha using PixelMath, setting the output for greyscale, but it all depends on the target and the contributions of the two channels, as you'd expect. Ha can sometimes create havoc with delicate blue reflection nebula and one goal was to retain the RGB combined blue in and around the Ghost. Much appreciated Steve - your Esprit 150 would make a lovely Ghost (if you haven't imaged it already). A four panel mosaic or larger is still an undertaking even when you have a greater frequency of clear skies; planning when to collect Ha, when to collect the Blues etc is all important if you are aiming to stretch your technique.
  18. I am pleased to have completed another goal with this 4 panel mosaic of the Gamma Cass evocative nebula "The Ghost" and the surrounding Ha nebula that wraps wave-like around the beautiful blue glow of Gamma Cass. I was inspired after seeing Olly Penrice's image back in 2017, here. Steve and I have persevered with weather since late October 2018 to bring together 88 hours of data. A marathon processing evening yesterday gave me the main image with finishing touches after work today. We have a vague notion to fill out the mosaic and to connect to NGC281 . . . but not just yet thank goodness. On my Astrobin page I have also posted a rotated version to better see the "Breaking Wave", https://astrob.in/385005/0/. Thanks for looking & enjoy the full resolution and the sharp optics of the Tak FSQ106. Details: Tak FSQ106 at F5 10 Micron GM1000HPS QSI683wsg-8 with Astrodon filters SGP & PI Ha 84 x 1200s; Lum 144 x 600s; RGB 74 x 600s each
  19. Refreshing to see an unusual galxy target - lovely dynamic feel to the framing too. Great image Olly.
  20. Thanks Rodd: gently does it with PI and small incremental applications of processes. Thanks Scott. I'm reasonably lucky to live at the edge of Totnes and have (for the UK) relatively dark skies.
  21. Thank you tomato, Paddy, Wim, Ken, andyo, bob-c and Olly. I do indeed know of 'Old Wexi' and his great tutorials. If I want to push the faint background stuff I tend to use the specific scripts for this and combine with masks and Pixel Math etc. I have used the techniques from the link before, and his web pages are a great resource. Thanks Olly. That's how I felt with this particular image, wanting to preserve the IFN's imperceptible wisps and focus on the two galaxies. Now when I get round to a widefield of this area . . . I really want to stress the extent of the IFN and will push to bring it much more to the fore.
  22. Thank you both. Cheers - would work well in your 115mm too if you haven't imaged this pair. Thank you both.
  23. I have been waiting for clear skies in the late evening to gather further subs on another Gnomus/Wilson galactic collaboration designed to make the most of our focal lengths and imaging scales and the vageries of the UK winter . . . watch this space. However, opportunistically, I've managed over several nights to grab subs here and there in short cloud-free gaps in the early evening of M81 and M82 before being inundated with thick all covering cloud. I've captured 8.5 hours of LRGB all at 600s at the native FL of my WO FLT132 giving me 1.2"/px with my QSI683 enough to give some detail and also the faint IFN. I wanted to retain a natural feel to this classic image of the pairing without pushing so hard in the luminance to make the IFN clear and running the risk of the dreaded PI-ing of the image. At F7 in my current configuration I have a nice image scale but relatively slow for the IFN (but it isn't my main goal) and I hope I've left it hinted-at yet probably relatively fairly protrayed in the relative brightness levels of the image subjects. A widefield view of this area to properly display the IFN is planned (and I do have some subs in the bag) with one of my faster refractors and I will let the PI-demon inside loose a little to reveal the galactic cirrus at that future date . Until then, the iconic pairing in LRGB is below. I've been pleased to see a faint blue to the outer tips of M82 recalling a thread and discussion about this when Paddy presented a DSW M82 some weeks/months ago and particularly pleased with the active jets: not bad without any Ha and for a balding fella in his backgarden . Fingers crossed for clear skies for us all in the coming weeks! Barry
  24. Yes, I have. Without reducer at F5.3 I have a flat field. With reducer I get 3 perfect corners and my top left corner (as viewed on my monitor) has a small amount of tilt. Endlessly tweaking the 3 grub screws on the reducer has never fully removed it but has reduced it to a small fraction of a small tilt! I have replaced the grub screws in the reducer, drilling out the holes and replacing with larger diameter caphead screws: this helped deliver more control to the adjustments. I have removed the CAA and examined it but not been able to make any adjustment with it. My top-left tilt is small and not readily noticeable except by me. My last tweaking gave an almost perfect field until I decided to rotate the ccd for framing and back came the small amount of tilt. I have taken the plunge and bought the 3" FT focuser with tak adapter from Starlight but not had it delivered yet. I am hoping that this will deliver perfect results!
