Progressing slightly from the previous M57 image, which was Ha only, here I present Ha and OIII combined, with OIII in blue and Ha in green and red. Irritatingly, the polar alignment has shifted slight in altitude, hence the smeared stars - but that said it's still a pretty good image. It's pretty rich in detail in the nebula, and if the cloud hadn't been more or less constant I would have fixed the polar alignment and got a LOT more images. SII didn't work out because the cloud really rolled in, and there was a little mist on the corrector but with it being a school night and getting on past 11pm, and I don't want to be up too late...this time!
I need to get better focus on the SIII images, and I'm seriously tempted to remove the focal reducer from the frame to try and get even more detail. I think I've also aligned the camera 180 degrees clockwise from where it was in the last session, which doesn't help or I would be combining my previous Ha images. But since it's still very early with the new equipment, and it was a limited session due to time and cloud, I'm pretty happy with the result.
