M13 RGB via the C11 @ f/10

I am extremely pleased with the outcome of this one 🙂

It took a while to get the C11 sorted, getting the SXV M25C in focus, and then getting the Off Axis Guider parfocal…. never want to do that again, but the result was just incredible. Perfect round stars, even when imaging at 2800mm focal length from a mount that was outside. The data was so good that I managed to drizzle stack this for 6000×4000 and the image data is still incredibly good…

Poor weather means more M42 reprocessing

Sorry, but with the weather and cloud cover being the way it is, the only thing keeping me sane is reprocessing previous data. Two versions this time. With the first one, I was going for the light and fluffy look, and the second version was the harsh and colorful look. I think I pushed both options about as far as I could. I still prefer the light and fluffy version. Click on the images for larger versions

M13 against the moonlight

After 60+ days of not getting any useful images out of my cameras, the weather gods finally realised that it wasnt funny anymore, and gave me an entire night to play with the stars. The fact that I kind of messed up most of the night doesnt really count 🙂

This was taken on Friday morning, fighting the 68% illuminated moon. Its kind of washed out the colours, but I`m not all that bothered by that. Discovered some flex in the system (C11 vixen dovetail maybe?), so had to decrease the length of each sub to reduce trailing
