Sh2-155 (Cave Nebula) in HST palette

Recommended Posts

Hi

This is of Sh2-155 (Cave Nebula) in the wavelength ordered palette (HST) and was taken with a FSQ106ED at f5 on a Paramount ME, the camera was a FLI ML8300 with exposures of 8x30 minutes SII, 12x30 minutes Ha and 10x30 minutes OIII. The Ha version can be seen on the home page of my website http://www.imagingtheheavens.co.uk

There is a full size version at the following link

There are a lot of interesting subjects in the Sharpless catalogue so I may continue looking through them

Thanks for looking

Best wishes

Gordon

Hi Gordon, something heavenly about that image. I'm expecting St Peter to pop his head out from behind the cloud. I like the NB ratios. I'll have to experiment with that.

Thanks guys

I've found that since doing mainly narrow band imaging the only way to get decent results is plenty of good quality data which means lots of hours at the scope, there just aren't any short cuts unless you have an EV2 or fairchild equipped camera with a QE of over 95%, but then again you would need a huge bank balance to pay for the camera. I'm lucky in that I enjoy being outside during the long dark nights so it suits me.......now if only the weather could play ball a bit more often;-)

Best wishes

Gordon
