NGC896 Heart Nebula

30 Nov 2024

This is part of the Heart Nebula. Unfortunately, it’s larger than my FOV but I’ve got the most interesting part. The data for this was good but there’s so many ways to process it that I got somewhat lost. This is the result of a week of trying over and over until I have something that I’m half happy with. No doubt I’ll process it yet again at some point. Note WeBo1 at the bottom left. This was only discovered in 1995 and now every hobbyist with even cheap equipment can see it!

IC405 Flaming Star Nebula

20 Nov 2024

This is the flaming star nebula. I’ve never imaged this target before so I was excited to see what I could get from it, especially as a first narrowband image on my new scope. The sky was variable quality and a few days after full moon. I managed to get 4 hours of data on this target with really good guiding and very low hfr. I processed as usual with Siril and with Graxpert and I’m so happy with the result, I’m tempted to move onto another target rather than get more time here.

M33 Triangulum Galaxy

12 Nov 2024

This is M33 Triangulum Galaxy. It’s not a great image but it’s first light on my new William Optics GT71. Unfortunately, it was taken on a night where the moon was almost full and I only had a few hours of clear sky. Never the less, I’m happy with it for just 2 hours exposure. It’s mostly ok with a little bit of adjustment needed to improve backfocus. I have a filter drawer to add anyway so this can wait until later.

NGC 7822

28 Sep 2024

This is NGC7822. It’s a star forming region of Cepheus. I captured this over a number of weeks given the poor weather we’ve had recently. I used HDR mode on my Risingcam with sub lengths of 5mins or 10mins. Despite this, the resulting stack had low signal. I think I’ll avoid HDR mode for narrowband in future. Anyway, I’m reasonably happy with the results. This region is begging for a mosaic and perhaps I’ll get around to it one day.

NGC 6914

31 Aug 2024

This is NGC 6914. It’s a both a reflection nebula and an emission nebula in the constellation of Cygnus located almost 6000 light years away. Capturing this target has to be a 2-step process unless you’re in a very dark sky area. I captured the Ha and OIII emissions using an sv220 narrowband filter in my Bortle 6 sky at home and the broadband data was collected when I was in Bortle 2 sky in Wales
