  1. Thank you for the high praise! It is indeed very satisfying to get this kind of feedback. After a many years of doing this, some things get normal and nothing special anymore. It does give back the joy to see how certain images can get such positive feedback. Kind regards, Graem
  2. Oh my, what a flood of responses! I'm overwhelmed! Not used to so much feedback! Thank you very much for your kind words, very motivating. I'm feeling a little pucky from trying, i guess i need those magic 3d glasses I'm proud to have never upgraded, even if i have been tempted many times before! It does have its limits though.... I'm in a pretty sexy spot on my piece of land. 0.64 on the lightpollution map VIIRS 2018 (light blue). Its getting worse and worse as major cities in poland are expanding fast, but i guess i've got another 5-10 years until it gets unuseable! I did experiment with drizzling, but for it to work in long exposure, based on my research & trial, you need to have pretty good seeing. If seeing is your limiting factor, then drizzling will not get you very much further. But please correct me if i'm wrong! Drizzling even with video astrophotography (moon) did not make huge improvements in my case, as again, seeing was my limiting factor. Thank you again all for your kind words! A nice surprise! Kind regards, Graem
  3. Hi everybody. I always thought i could do a little better with M51, especially that it is one of the most interesting galaxies for a rather wide angle scope like my ED80 (next to andromeda obviously). I continuously added data, and finally got to processing. It was a joy to pull out so much more detail, not only due to more signal, but also improved processing skills over the years. Side by side for comparison (all data from 100% same setup). Left is approx 12h, right is approx 19h exposure. And here the final image (as usual it gets pretty bright when posting here, due to colour profiles). Stars are horrendous but thats another topic... Hope you like it! Kind regards, Graem
  4. Great capture! Andromeda is a very rewarding target! It was one of my first, and also the first time i got stuck with the car in the field at 1am in the morning I'm sure that if you add the calibration frames and maybe a little more exposure time, you'll also get rid of most of the noise, and also the colour blotching in the background. Congrats! Kind regards, Graem
  5. A phenomenal image Rodd. Nowadays not much impresses me anymore, this one did! Kind regards, Graem
  6. Hi Carole, thank you for your nice Feedback! OIII is a nightmare indeed. Going the tone mapping approach was the only way i could get anything useful from the data, but removing OIII halos were a painful manual process due to my inferior equipment. But i don't regret it! Kind regards, Graem
  7. Hey David, thank you for your kind words! The only thing i do is add it on flickr in some groups and on astrobin, if it gets picked up there sometime somehow, i'll not say no Kind regards, Graem
  8. Thank you very much Olly! I really was trying to get it as natural as possible, nice to see that i've not gone too far off. This is also due to your help in May 2017, it took me a while to experiment with all the different possibilities of getting the most efficient and pleasant to work route (not sure if you remember you helped me on this one!) I wasn't too happy with it then, so let it rest for a year or so to brew along
  9. Thank you very much, Gorann! Your feedback concerning the signature is valued, thank you! In the Print-Versions (not published) it is way smaller, but in the Web Versions, as its displayed rather small, i try to keep it at a certain size, so its still readable, and i try always to position it in a way that its not in an interesting part of the image and 'shouldn't' disturb. I'll take it into consideration though in future placements & size decisions! Kind regards, Graem
  10. Wow guys you're making me blush! I didn't expect such positive reactions. You've made me a very nice Christmas present! Kind regards, Graem
  11. I was at exactly the same point not too long ago. It felt wrong to mix 2 softwares, but the possibilities when it comes to layers, masks, clipping masks etc Photoshop (at least for me) wins by lengths. THere is no comparison. But i love PI for the mathematical aspects and also Noise Reduction / HDRCombination / Mosaic merging, where Photoshop doesn't have the same capabilities. I'd highly advise you to give Photoshop a chance and read into it (astro-tutorials, or also here on the forum) to then make your own opinion. My biggest problem to date was 'where is the 'MASTER' history, as when you're switching between softwares, its still nice to be able to keep the history. I've not figured that one out quite yet though. Lightroom i love, but not for Astro. I've also not seen too many people use Lightroom for that usecase. Lightroom for me is more for simpler adjustment tasks & cataloging, i've never seen layers or masks in the context you'd use them for astro-image-processing. Kind regards, Graem
  12. Thx Ken! Thank you Dave. That observatory took every last bit of patience and energy out of me for the first 1-2 years, but now that its up and running, and i know the quirks of the system, its a joy and makes all the images possible. Kind regards, Graem
  13. Thank you for your kind words! We do have a terrible hobby when it comes to patience...... Currently i'm using a combination of Pixinsight and Photoshop, whereby lots of the processing nowadays has shifted to Photoshop and i'm using Pixinsight only for the Mathematical aspects (Staralignment, Calibration etc). But if i've learnt something, its really not what software you use, its the skills, tricks etc you gather over the years. I've seen people do amazing stuff in the free Gimp software, that is far behind any of these other Softwares. Thank you so much! Thx for your approval. I was and still am very unsure always, and i'm terrible at estimating colours. Nice to see it does seem acceptable also for others :)! Kind regards, Graem
  14. Thank you Steve for your encouraging words! Kind regards, Graem
  15. Hi everybody. Data from End 2016 / Beginning 2017, i couldn't let that rest unprocessed until 2019! Had to be done. I on purpose tried to keep it calm and not over-do the saturation, even if i'm still very unsure about the strength of the red. It's in total approx 18h exposure over multiple months. Classic Bi-Color but still added the RGB star color as it just felt right in this case. (And yes, i have bad blue / purple squint on the stars due to inferior equipment, i got used to it instead of fighting it too much...) Hope you like it!
