Horse head and flame

I’ve been reading a lot recently about camera noise and recommended ISO settings for each particular camera for astronomy. The camera I’ve been using was said to perform best at ISO 1600 which I think in astronomy terms is actually quite high for a Dslr. So I decided to test this out on the 8th Feb and managed 74x1min exposures at ISO 1600. I was very pleased with the low noise, although the light pollution south of me (Tamworth, Birmingham) was very strong since the horse head is relatively low on the horizon. I’m pleased with the result, although I think with a bit more processing experience I could possibly improve the image???  I was trying out Pixinsight for a second time so I hope to improve over the coming months/years. Canon 6d+Idas d1+Takahashi fsq.




For some time now I’ve been absolutely fascinated by the Pleiades! On some clear evenings ill set up my lunt 70mm bins on a tripod so my wife can have a look and it never fails to disappoint! I was checking the weather all week and finally on the Friday evening a clear night was forecast. I planned for Nick to join me with his 9″evo and we sat about imaging the Pleiades and the ring nebula. Nick got some lovely pictures of the ring which should follow shortly and i ended up with 12x3min exposures of M45. Ive still got some post processing to do with my image but I’ll change it over when complete.


North American Nebula

SGL 2017

Myself and Nick went to the SGL 2017 event in Lucksall for a weekend in October. The weather was very cloudy for most of the time but we had a very brief period on the Saturday evening where the cloud dissipated. This led to panic stations getting polar aligned and maximising the number of images. I had decided on the North American Nebula as it had just passed the meridian at the point of clearing and I didn’t want to footer around with a meridian flip half way through. I set up to do 30×8 min exposures but sadly the weather started to cloud over again after the first hour or so. I managed to capture 6×8 min subs which I stacked on DSS. I was using a Takahashi fsq 85 and modified canon 6d with an Idas D1 filter.
