Hello everyone!
I had such big plans for last night. I wanted to try and image NGC6520/B86 but my mount had other ideas! Well actually, it wasn't so much my mount but my poor setting up which meant that my initially alignment was off. This meant that no matter how much I tried with the Goto I could not find my target.
So, rather than pack up everything after 3 hours of setting up and the subsequent frustration, I settled on M4 as it was easy to find. Not my favourite target, in fact not a target I like at all. Anyway I imaged for an hour (20 x 3 minute subs) and the result is attached. I used my method to compensate for the UHC-S filter and I am (happily

) getting colours in the stars.
Other points - RC8 on an HEQ5 Pro mount, QHY8L OSC and guiding with a QHY5/ST80 combo and PHD.
It's not much but I'm so desperate to image that I'm posting it anyway...
Cheers,
Mario
