  1. I guess I'll email FLO tomorrow and bring forth this issue to them. Let's see where this leads me because I'm just not pleased with the results no matter how I look at it.
  2. I think I'll go via FLO since I bought these filters off them. FLO are great and I take comfort in the fact that I'd be well looked after as always. I haven't thought about binning but not sure how that's supposed to help with this mate? Cheers for the super valuable inputs Ken, ah I thought the image of elephant was from the 3nm filters. Jesus, you did give me the scare there mate Yeah I don't doubt FLOs customer service but before I started to bug them, I thought I'd check here first and see what users of Chroma 3nm experienced and apologies I should've asked you first before tagging you but made sense in my head at the time to do so because it was your super useful thread here which lead me to the CN thread and also I thought it would be best to hear from you since you noticed the issue quite recently so it might be something fairly new people have started to notice. Too kind for offering to lend me a refractor mate, I'm no way near Midlands unfortunately but I do have a refractor of my own. I am happy to test this out with the refractor but before I do that, I'd like to go back to my EdgeHD scope and see what that stars behaviour looks like after that I've flipped the filters. Yeah the filters and camera are square to each other.
  3. Yeah I absolutely went for these filters because of their reputation, the results achieved and of course pairing it with the camera that I have. I just wanted to get in touch with the community here to see what anyone else thinks about it or if they have experienced it themselves. Will get in touch with FLO tomorrow and see what plan of action we come up with. Will keep you posted Graham.
  4. Unfortunately they are worthless to me if it doesn't work the way they are intended. I don't have to put up with software wizardry to fix something that shouldn't even be present in the first place. I really can't put up with this especially I paid nearly £500 per filter. If I was imaging a bright star then yes it makes sense for the microlensing effect to be very much visible and may even have the newtonian rings but on a small star? Certainly something is not right here.
  5. Thank you for the link and your input Ken. The CN thread is mostly tested on a super bright star which I won't ever be going anywhere near to but your data has somewhat smallish star in the elephant trunk image. Did you try flipping the filters afterwards to see if this effect goes away? This really worries me because I've paid a good chunk on these filters which are going to be worthless if they are not going to work for me. It really is heart breaking to say the least.
  6. Sure mate, it's https://www.cloudynights.com/topic/715162-chroma-3nm-orientation/
  7. OK but this is a big boy star. The stars that I am seeing these halos and banding are on smaller stars but bigger of the bunch if it makes sense.
  8. True, it doesn't look like a regular halo-ing and I can promise you these halo in the "bottom right corner" image (in the integrated) is so prominent on the TV screen that I use than on the mobile phone. I checked with FLO and they were kind enough to tell me the same thing thay orientation doesn't matter but then like I said there's a thread on CN which was from this year shows exactly that the orientation does matter. Now even though my filters were in the "suggeted" orientation, it still produced this. Now I've flipped them to see what happens but can't test them out until wr have the next clear night which God knows when is going to be happening.
  9. I'm certainly not the first person to use this combination of camera and filters because otherwise you'd be hearing about it all over the web which we're not. Unfortunately I don't have enough money to be spending on a different camera and neither can I ask someone for it.
  10. Unfortunately it's not the microlensing effect. That has a total different pattern and doesn't produce halos.
  11. Hi there, I'm reaching out to all Chroma 3nm NB filters users to find out if they have ever noticed what I am doing right now. I purchased the filters from @FLOduring the first lockdown. A few things happened in my life which put a stop to anything I wanted to do and AP was one of them and only just started to process images since I've had the filters so I am a little late on testing. I'm seeing halos!!! I did not notice anything in the individual subs when I was capturing it but then I wasn't expecting much to go wrong with these filters. It's only when I started to integrate the light frames is when the issue became quite evident. The first image that I processed didn't have many bright stars to take notice of the halos but the second image showed them. The first time I noticed them was when using Starnet, all the bright stars had a halo around them. Even though I wasn't happy about the fact that the 3nm still showed too many stars and bloated especially coming from 6nm, I thought that maybe I pushed the data too far and carried on processing the data. The first image was fine, only because it wasn't a fended star field but the second image showed the stars a bit too much for my liking that I really had to do star reduction. Now when I got the filters, I did ask if the orientation mattered and I was told that it didn't so I placed the reflective side (top writing) towards the camera and non/less-reflective side towards the scope end. When this issue started to bug me, I noticed that @Ken82mentioned here the filter orientation had to be in a particular way which then took me to a CN thread where it was again mentioned which way the filters had to be. The solution was to flip the filters. When I opened up the FW tonight, I realised that my filters were the positioned the correct (sugggested) way. I still flipped them because I have no other choice. The scope that I used was EdgeHD 8" with ASI1600MM-COOLED camera. This is what my individual subs look like Bottom right hand corner: Middle: It might not look much from these screenshots but I could definitely see this on my PC. OIII for the "middle" screenshot doesn't show much but in the corners it still does. Chose the corner because that's where the bright star was positioned. Below is the integrated SII which shows the banding for the middle image The integrated subs for all channels (bottom right corner) The integrated subs for all channels (middle) Any advice/help is much appreciated. Thanks.
  12. Maybe you both are right. I haven't checked the price of the reducers in a long time but just coming from seeing what these thing cost straight away felt slightly expensive. This hobby is expensive on its own and I guess it's still £300
  13. This I'm sure is such a welcome news for Esprit owners. Slightly on the expensive side of things don't you think?
  14. So good to see another one of your master pieces Brendan. We were speaking on Facebook regarding my NGC1491 target yesterday and this is exactly why I think your work should be seen by the world of astrobin
  15. Hahahaha I've been using uni gain myself but the darks are really helpful in removing cold and hot pixels. Trust me, you'll find them super useful
  16. What gain and offset settings did you use mate?
  17. What great result. I've seen so many people jump to MaximDL's deconvolution process. Love the colours. Top stuff mate.
  18. Absolutely stunning. Mind if I ask what filters did you use and what software did you use for processing?
  19. Nice one, would love to be on this journey with you and see how you progress through it. Good lucky mate.
  20. Got a link to the sort of canister you've been using? Just out of sheer curiosity. Thanks
  21. Joy's of living in a Bortle 4 scale. I can not even think of imaging anything remotely rgb in my bortle 8 skies. 🤦‍♂️
  22. What a brilliant image Adam. Not overly stretched, beautiful star colours... Just perfect. What's your bortle scale if you don't mind me asking matey?
  23. Absolutely beautiful Gina... I mean the picture... You as well and you know it
