Messier 97 with the VC200L

[RichieJarvis]

Hi All,

Another Vixen VC200L shot. This time, M97 at the scopes native focal length. I shot Sii as well, but there isn't enough there to warrent including it (in fact, M97 looks REALLY strange in Hubble Palette I've discovered!)

Ha: 27x600

Oiii: 15x600

Thanks for looking!

Cheers,

Richie

I can confirm that there is next to no SII in this object but isn't it alive with OIII?

Very nice capture with the vixen, just out of interest what camera did you use Richie?

[RichieJarvis]

Isn't it just Steve!

The SXV-H9 was used Neil....

Looking at the spectrum: Spectrum Display Page

Owl emits light in:

- O-III

- H-beta

- H-alfa

- N-II (should be captured by ~12-7nm H-alfa filter)

- and very small ammount in S-II

When I did 20 min subs on it with SII there was very very little data produced.

There is a peculiar extra outer layer, and quite possibly another one in OIII. It is the hardest thing I have ever tried to capture, needing a dark sky and no moon and good transparency....(we get loads of those nights dont we.....).

The smudge around one of the stars close to it is actually a little galaxy.

The tube seems to perform pretty well Richie.

The tube does TJ, but am having nightmare probs with guiding to be honest. I can't run more than 6 minute subs at the moment

Need to fix that to do the best for this tube.

Cheers,

Richie

flex I guess, time for an oag Richie

[RichieJarvis]

Nope - just confirmed it as going the wrong way in WCS! D'oh....

Its polar alignment - at least thats easy to fix though
