Richard,
The QHY5 is a great little camera for planetary work and you've got it working well. It also looks like you've got a good handle of how to use wavelets in Registax to bring out the detail nicely - I use it all the time!
I've since upgraded to a QHY5V colour camera as I wanted to get my planetary shots in colour and I've also moved to using eye-piece projection to try and fill the chip and give me a bigger image.
Keep up the good work!
Cheers,
Mario
PS If you're interested to see what I've been able to do with the QHY5, QHY5V and eye-piece projection, have a look at my AstroBin profile - the link is below in my signature
