  1. Ok, got some more data tonight and have got this. Not sure I can get better than this.
  2. Thanks. I think I have managed to get something more realistic. I hope you don't mind that I downloaded and manipulated your image in PI to help with DBE @ollypenrice. I cropped the fov similar to mine, removed the stars and based on your image, selectively placed my DBE points. You can see the comparison below. Leaving aside the huge quality difference in the images I can now start to see similar structures in the dust now. Btw fantastic image Olly. Removing the stars realy emphasises the amount of dust around here! I'll need significantly more integration to get close to this, if I ever can!
  3. All you need is a cheap intervalometer. You should be able to find one on Amazon for £20-30. That will allow you do multiple and longer exposures.
  4. I would have hoped DBE on PixInsight could have handled it. Probably user error as sample placement is important there too. Is Siril free? Looking forward to hear what @alacant done as that looks more like what I was expecting.
  5. I’m Bortle 4 where I’m located but mainly shooting towards Bortle 3/2 which helps. The IFN is nice but a pain to process! If you tell me how I will! That looks great 😊
  6. Thanks for the reply. I should have mentioned that. I used darks and flats but they weren’t shot on the night. I just used ‘master’ ones. That could very well be the problem . I’ll shoot new ones tomorrow but it may already be a lost cause. At least it wasn’t a full night of data wasted!
  7. I recently imaged M45 for the first time in years and in all honesty my first proper try. Even at that I only managed just over an hour due to clouds. When I came to process it I had real challenges with gradients. I knew there is a lot of dust in the ara but I seemed to have a strange radial gradient that I was not fully able to remove. I found an Adam Block video that had something similar and I tried his process but I'm not sure I have been successful. I can see I have some of the dust I expected there and more exposure would help obviously but there is also something else. Still looks like a radial gradient? Please comment if you have seen this too. Tak FS60 with X.72 reducer Zwo ASI2600MC 23x300sec Processed in PixInsight
  8. A small group of amateur astronomers have discovered an emission arc in OIII close to M31. Seems to be a bit of speculation regarding it’s origin but given how much that area is imaged it’s amazing this hasn’t been noticed before. Having said that most people aren’t gathering over 100 hours of data, including 45h of OIII there! Good to know there’s still so much out there even in an area of sky where telescopes are regularly aimed. Image credit Marcel Drechsler, Xavier Strottner and Yann Sainty.

  9. Thanks! I'm not sure I have followed this as you intended as the stars were coming from the RGB image and the starless from the l-extreme image but I have given it a go. I was also a little less aggressive in the starless processing and left more stars in but overall this is probably a more balanced version. Now I wasn't so lazy though 😆 Let me know if you think I have followed this correctly. Appreciate your input!
  10. Yeah it's there, faint as you say. A little clearer in the starless version. Actually I had issues with my stars in both the l-extreme and RGB data. L-extreme had halos and I think I blew out the stars in my RGB with 180s exposures. Perhaps that's why they are clipped? In any case I removed the stars using star net and just used the simple 'starless + stars' in pixel math. I'll take a look at the RGB stars again. See if I can get more natural colours.
  11. Thanks, if I can get away with it the lazy way will be the future for me!
  12. I haven’t had the motivation for imaging (or processing) recently but collected some wide field data around Sadr and the Crescent nebula with my ZWO ASI 2600MC and Takahashi FS-60 with reducer for the first time. There is issues with tilt and/ or spacing that need addressing at some point. This was a very lazy capture and process. No calibration frames, automatic background extractor on PixInsight. Used the STF function for the stretch and used Bill Blanshan NB normalisation process to create a Hubble palette from the L-extreme data. Stretched the RGB stars separately and added back with PixelMath. Think I might just take the lazy route from now on! Not sure the time I normally spend would improve this much. 30x300s with L-extreme 20x180s RGB
  13. Wondering if anyone has had their EOS R modded and if they can recommend anyone for the service? Preferably in the UK but will consider abroad. Thanks!
  14. Thanks Alan! It’s all a little tongue in cheek, nothing but an excuse to treat myself! Which, by the sounds of it you deserve to do too. I can wholeheartedly recommend Takahashi to help in a crisis, manufactured or not 😉
  15. I’m going to take another look at the rings. Maybe I’m being a bit too cautious but some extra felt wouldn’t go a miss. I do like the look of a three ring set up too. Looks very robust.
  16. This should keep me happy until 50 at least 😉😊 Cant wait to get it out under the night sky! Not much chance of that in Norway just now but there might be a small window for the planets. This was actually ordered from Japan along with the flattener for the TSA and a reducer for my FS-60. I was pleasantly surprised to find it includes the finder scope and bracket too so I saved even more money than I thought. Even after the high shipping cost and import taxes etc I still ended up with a >20% saving. Fingers crossed everything is ok optically. My only concern is the rings I bought. You can see that they don’t fit flush and I didn’t dare tighten them any further. The scope seems secure but there are some vibrations when I touch it while locked in the saddle. Not sure if the rings could be the source of that?
  17. I feel the crisis may have been averted 😆 More pictures to follow… 🔭
  18. I would hope the performance of the base model is not too far off this at the focal length they’re showing anyway. I think the encoders are more for unguided or guiding at long FL. Never sure how much to trust these marketing graphs but even if it’s 0.6-0.8" range I’d be happy
  19. iOptron have posted an FAQ on the HEM27. Really curious to see how the hybrid v fully harmonic works out in practice. Was close to pre-ordering but think I’ll wait to see some results first. No darkness here just now anyway. https://www.ioptron.com/Articles.asp?ID=346
  20. Thank you 😊 Haha, you need to book in your midlife crisis with the lead time on new astro products these days!
  21. With the set up I would have, ASI2600MC (3.7µm) it would give me 0.86”/pixel at native 900mm FL then 1.2"/ pixel with reducer at 650mm FL. I also have an EOS R with 5.4µm I could use so I think that should cover my bases? Image circle is 40mm with flattener and 44mm with reducer according to Takahashi.
  22. Thanks, got some helpful advice from you re my FS60Q. I may have caught the Tak bug!
  23. I recently turned 40 and after a rush of blood to the head I sold my Esprit 100. I may live to regret that but the upside is it opens up the possibility for a new scope. I’m mainly into imaging but I’ve found myself drawn more and more to visual so I’m looking for a scope that does a bit of everything. I’m aware that doesn’t exist but from what I see the Tak TSA 120 might come close. It seems to get rave reviews for visual, particularly lunar and planetary. At native FL it gives a bit more reach for galaxies, and with reducer it gets me close to what the Esprit was giving me. Does anyone here use this for imaging and visual? I’m happy to hear other suggestions if you have any. I should say I’m limited by my CEM40 mount which I have no plans to upgrade.
  24. Who said anything about comparing colour correction? 🤷🏻‍♂️ The post was to alert people that may have ordered thinking they were getting an FPL-53 triplet and are likely actually getting an FPL-51 triplet.
