Cone Nebula
I finally had an opportunity last night to try out the new Ha filter. I managed 180 mins in 10 min subs before I found the QHY8 had some dew forming on the front at which point I chucked it in. I'm dissapointed in the noise in the image - obviously need to go for longer subs however the good news is I have almost no flexure so should be able to try longer subs. I also need to take some 10 min darks as I don't have any in the library and maybe this will improve things a bit.
I've included an image from ESO I was using to frame the object for a comparison just for fun!
