Hi all, my second attempt at imaging over multiple nights, captured 60 mins Ha and a couple of 5 mins on Oiii and Sii on Christmas evening, then added more Oii and Sii on the 30th
Total of 60 mins Ha 25 mins Sii and 30 mins Oiii
Hubble mapped - SII,Ha,OIII = R,G,B. The Oiii data was very noisy but I'm fairly happy overall, also the ZWO Oiii filter caused a massive ring around Alnitak when stretched !
Comments welcome, I know it needs more data and I will need to learn to be more patient but the year is running out 🙂
Thanks for looking and have a good 2020.
I went to my family house in the countryside and was able to take some pictures during xmas eve.
Total exposure: 6h
H_Alpha: ~3h (730x15s) --> R, G
Oxigen III: ~3h (710x15s) --> B, G
I didn't have a view on Polaris and could not spend too much time drift aligning (it was xmas eve after all :D) hence the short exposures. Moreover I dont have the proper connection rings to put my flattener on my mono camera so all stars off center are a mess :_(.
As new condition ultra narrowband 1.25" Baader filter. 3.5nm bandpass for nice small stars.
Bought and loved it, but using a DSLR again and have no use for this filter.
£140, can post.
Selling my full narrowband set up for multiple reasons: I could do with the money and mono just isn't really doing it for me.
Altair Astro 183m Tec
Baader Narrowband filters (Ha, OIII, SII and Clear)
ZWO Electronic Mini Filter Wheel
All associated cables/plugs
T2 extensions to reach 55mm back focus for use with reducers
Boxes and cases
There is a scratch on the T2-T2 adaptor for the filter wheel and a couple of the labels on the filter boxes have been torn. But otherwise the important parts work perfectly well.
Collection or postage via DPD.
Buyer to pay postage and PayPal fees.

This has been my project since the start of this season and now I think I´ll just leave it... for now 😉
I started last season (with a longer FL) but didn´t like how my Baader O3 filter matched the Astrodon Ha filter, so now I had to get a 3nm O3 as well.
This is a total of:
60*5 minutes of 3nm Ha
114*5 minutes of 3nm O3.
Shot with a ZWO ASI1600MM-Cool and a Canon 300/4L IS tele lens. The lens suffers from bad star shapes in the corners but I managed to get it decent anyway. Didn´t want to stop it down from f/4 either.
Combined as a semi-RGB (or what to call it) from R=Ha, G=70%O3+30%Ha, B=O3. Processed it as LRGB using a combined Lum from 60% Ha L and 40% O3 L.
I am really happy that I finally feel satisfied with a target! Usually I just get restless and move on when half of the data is collected.
Hope you like it!
