(Still) A work in Progress... Crescent Nebula...

Recommended Posts

Hi All,

Here is the latest processing of my Crescent Nebula data. I've added 7 x 900 second exposures to the set now, and I think it really benefits from the longer exposures.

I also discovered that my Oiii data was out of focus :D So, its back to the drawing board (or to the telescope) to capture another block of Oiii data. I am determined to get a decent Crescent Nebula this year though!

Finally getting to grips with the SXVR-H18 - after a few wobbles, I think it is going to be alright :mad:

Now that's pretty darned crisp. The Vixen has resolution in spades (nothing wrong with the focus here!) The thick spider vanes take their toll on brighter stars but that apart the scope is doing really well, I'd say.
