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.
During the 3 clear nights in a row, I had last week, I could not resist giving the Horsehead Nebula a go, using my Vixen VC200L.
Whilst imaging with my Canon 450D via APT, I could not make out the Horse's head whatsoever on my laptop screen, but I knew I was on target, because I could see NGC2023, at the bottom of my screen.
Anyway I was pleasantly suprised with this result after processing through APP and tweaking in GIMP.
Not the total failure I was expecting.

Just had a lovely session on the winter targets that are now coming into view in the early hours. These were the targets that I first tried out my NV monoculars when I got them in November last year so it’s nice to give them another go with the greater experience and better equipment I have now.
This was also the first proper go with my Harder Digital Night Vision momoculars and chroma 5nm Ha filter combination. The views were fantastic - I compared side by side with my photonis 4g Night Vision and 6nm Astronomik filter and the gap between the two setups is large.
The angelfish was clear and showed good detail with the Harder whereas the photonis was only just showing a trace of the nebula. On Barnard’s loop the full loop was clear and obvious in the Harder whereas the photonis only showed the brighter top half. This was on 21.0 SQM skies.
There was just so much nebulosity showing everywhere with the Harder which I haven’t seen like this before. Lots of new things to have a look at in greater detail in the future.
With my AP130GTX and 40mm plossl (with 5nm chroma) the views of the horsehead, rosette, monkeyhead, flaming star, heart, California, Pac-Man, the Cone and Lowers were also pretty fabulous.
All photos were with my Huawei P20 Pro, unprocessed.
I’m really chuffed with my new kit! One of my best sessions ever.
I've been sitting on this data for quite a while (it's from Jan 2017). I've had a few goes at trying to process it, but always junked the results - mostly because of Alnitak!
I've bitten the bullet and just posting it here to try and draw a line under this lot (and I've not done much else recently - illness and summer light nights...). Flare and scattered light in the field hasn't helped me and there's a bit of fringing with the brightness of the star. I have since cleaned the objective on the FLT110 as it was filthy, and I may have struggled with transparency, but I'm not sure what else I could do here to bring out more detail or contrast into the image with Alnitak sitting in the field - it just feels a little "soft" ?♂️. It also throws the colour balance off a bit - I think this is an Ok version, but the Flame is perhaps a little on the red side.
