  1. Congrats Adam on a great image! And just like you say, nice to see somewhere close to home get a nod amongst all the global images
  2. All the best to you and the Mrs @vlaiv. Hope you are both back fighting fit soon
  3. Thanks Chilli Thanks Sunshine. I only ever use ISO 200 on the D5300.
  4. Last Saturday night (Jul 18) i made a trip out to a local dark sky site. I had the pleasure of having the company of Adam @tooth_dr who lives nearby, who very kindly agreed to join me and show me the way around (big thanks again Adam!). It was a great night. I got to see the comet naked eye, and the length of the tail was truly amazing to behold, once i managed to get away from the laptop screen and finally get some dark adaptation! Conditions started out great, then started to deteriorate when a heavy mist came in from nowhere. Because i was using the mount, my setup time wasn't the best, so by the time i actually started capturing, the best of the conditions had already passed. I then noticed that the scope had also already started to dew up. With no portable psu for dew control, i had no option but to just keep capturing and hope for the best. In total i captured 66 subs of 30s. Some were very dubious, to say the least. I tried doing several Comet-Only stacks in DSS. Best 8, 16, 25, 49, 60, 66. Apart from the obvious decrease in noise as the stack no. went up, i was surprised just how little difference there was between them all. The dust tail looked no different at all , and the Ion Tail looked better as the sub no. went up. I can only assume that the dewing up of the scope had acted as a collar on the quality of all the subs. So in the end i only ditched the worst 6, and just went with the remaining 60. HEQ5-Pro, D5300, 60 x 30s (30 mins), no filter, no guiding. ISO 200. Subs calibrated in APP. Comet and Stars stacked separately in DSS. Gradient Reduction and star colour calibration done in APP. Then everything combined in PS. Considering everything, i'm 'content' with how it came out in the end. I'll just have to wonder how much better it could have been if i had a means of dew control and the mist hadn't come along when it did. The 80ED also was never the right tool for the job, but it was the best one i had available. Note to self - time to get a proper lens for AP!
  5. It's not hard at all. Create a new layer and do a Selective Colour adjustment. Target the Blues only, then increase the Cyan and Magenta sliders, while decreasing the Yellow slider. You may have to do it more than once. Then just use a layer mask so that it only applies it to the Ion tail and nowhere else.
  6. Nice one Adam! Were you able to sort out the stacking in the end? Did you do a split approach of comet + stars? How many subs made it into this image? The sky background colour looks fine to me. The artefact running across the screen is a strange one alright. One possible solution might be to run starnet+ to get a starless version. Then susbtract it from the full version to get just the stars. Then go back to the starless version and use the clone stamp tool to fix the artefact. Then finally add the stars to this in blend mode lighten. ps - Loving the wee galaxy photo-bombing the image on the LHS btw! Crazy to think the difference in distance between the comet and the galaxy!
  7. Yes it was a great night, totally worth the drive out I'm still working my way through the data, hoping to have an image soon (although it's proving tricky as the conditions weren't great by the time i finally got collecting data). It was nice to see the comet with the naked eye (i would never have been able to do so from home, too much LP) and it's always nice to have some company too in this all-too-often-lonesome hobby of ours! lol. Thanks again for the meet up Adam, and showing me around the location
  8. Please tell me it was only this 1 sub Adam At least I managed to intersect the comet nicely
  9. If you have Photoshop and are up for doing it manually, then you can actually stack in PS. It won't be as good as using DSS or the like, but it might get you out of a jam. Have a look at this video, it shows very well what you need to do:
  10. Love this one Ken. It really gives the impression of the comet zipping through space. May I ask, were you just hedging your bets by doing various exposures from 5s to 30s? Did they actually prove useful in the final image, or would the 30s subs have just done on their own? Just thinking, did you use the shorter ones for the comet's core?
  11. It's still a while off yet, so could all change, but the forecast for Sunday is looking promising Adam. If it holds up, I might take a run up to Beaghmore to get away from the LP. It's only a 70 min drive from home, which isn't too bad. I might ask you for some advice on the lay of the land closer to the time if that's ok?
  12. I'm a glass half-full kind of guy (usually more concerned with what's in the glass!) so I'm quite sure that another opportunity will come up to see it I feel your pain mate. Fingers crossed it will still be photogenic for a while yet. Have you thought of getting to a dark sky spot the next clear night?
  13. This is spectacular. Easily the best one I've seen so far. Congrats Ken!
