  1. WOW WOW WOW Peter. I saw this go up on astrobin and was amazed!
  2. I'm 100% sure it's in the same way around as the Ha and Sii and they look fine so I'm pretty sure it's not that.
  3. Hi Gary, that's what we were talking about in the posts above, it's something with the Oiii filter. I have emailed Antlia for support on the matter. Wyvern
  4. Fantastic Image! and very well processed.
  5. I think I'll have to get it looked at then
  6. That's taken with an LED panel same as the other flats. No other Oiii filter I'm afraid I wonder if it could be defective, might ping Antlia and find out. Ha for comparison
  7. Yeah, that always happens with my Oiii. I'm not sure what causes it but I seem to see the same pattern in my flats, but only the Oiii any help would be very welcome. Wyvern
  8. Thanks Brian! After the first lot of subs I just had this tiny nebula (for my FoV) in the middle so I decided to go nuts on the Ha. To be honest I'm not sure why I did 300s rather than 600s but i think it worked in my favour as it's still pretty low in the sky at the moment so neither the guiding nor the HFR were great. Hopefully I'll be moving from my current 20.26 bortle 5 to a 21.26 bortle 4 soon which hopefully will make a difference.
  9. Total integration time 24.75h 143x 300s Ha 92x 300s Oiii 62x 300s Sii Processed as a starless image and RGB stars added. Captured on: Williams Optics GT81 QHY168M Antlia 3.5nm filters EQ6-R
  10. Good Evening All, After a nice streak of clear nights but not many narrowband targets about, at least not in my field of view from my garden. I've never been fully taken by the Wizard nebula, not in the same way as with the Jellyfish or the Rosette. But after a significant amount of imaging time it has started to reveal it's secrets. Total integration time 24.75h 143x 300s Ha 92x 300s Oiii 62x 300s Sii This shows the fainter details of the Ha around the nebula itself. Feedba
  11. Wow, that's quite a difference. Look forward to seeing the jellyfish subs. Would be good to compare to mine.
  12. Welcome! Wow, what a wonderful part of the world in which to live! I have to admit I'm not only a little envious of your dark skies but your seas as a diver too. Hope you enjoy the forums.
  13. These are the ones I use https://www.rothervalleyoptics.co.uk/antlia-oiii-35nm-ultra-narrowband-filter.html These are 3.5nm rather than 3nm. I'd be quite interested in seeing the difference between the two. I'm not convinced that the extra 0.5nm will make an awful lot of difference. Saying that I probably would have gone for them but they are a fairly new addition to the range.
  14. I haven't seen any yet really, a bit of bloating maybe on really bright stars. I think the brightest I have imaged are the 2 around the Jellyfish nebula for which you can see the data here
