One of my favourite targets but also a real pain as its so low on the horizon from my position. I was hoping to collect more data over the next few weeks but I have an issue now which will mean this target will likely pass.

Starless california
Trying to make a Hubble palette rendition of the california nebula is not easy. It took me 6hrs in OIII to acquire enough data for required signal to noise ratio. I could certainly add more data but for now I’m moving onto other targets. 6hrs Oiii,2hrs HA, 2hrs SII. Maybe revisit next year.
Crescent nebula region
I set out to image the california nebula but early on as It was low on the horizon I decided to get a few shots of the crescent nebula and region.
Very pleased for such a short integration but Id like to add the OIII and SII channels at some point.
9x5min HA

20min on the Horse (Horsehead Nebula & Flame Nebula)
I only had chance to take 4x5min on the horsehead last week as I was still working on ngc 281. But here is the result of my 20min.
One for the future !

Pacman nebula in hubble palette 30x5min HA OIII SII
I’ve never been a fan of the hubble palette but my wife appears to like them more than my RGB so maybe its time to take action 🙂

I’ve been working on the Pacman nebula over the past few days but I thought I’d make a start on the California the other night. I’m Just amazed the difference this mono camera is having for my narrowband images.
Look forward to adding some more subs and potentially OII and SII
16 x 5min HA

Elephant in hubble palette
I’ve decided to start processing some of my images again as i have a poor tendency to dwell on things for a while testing and testing. So here is the first one in hubble palette.
20x5min HA 36x5min Oiii 7x5min Sii
Hope you like it 🙂

M106 and companions
M106 from the 22nd and 23rd March. I havent been able to get any HA images of 106 yet but im pleased so far with the LRGB data. I did have an issue with what appears to be CA (chromatic aberration) although this is likely my fault as im new to combining RGB images. Ian King is currently looking at the scope for evaluation. 100×1.5min luminance 20×1.5min RGB
First HALRGB M101
Decided to add in some HA i had collected on M101 bringing out some lovely red star forming regions. Its a bit of a learning curve with this like everything in astronomy as i had to mask the master HA considerably before adding it to the red channel. By masking so heavily i inevitably discarded most of the HA data i had collected which is a disappointment but thats something ill know for future galaxy images.
