Default ASTRO: Thor's Helmet in Halpha

Last night I was blessed with another clear night. There was a lot of moon
and it was up high most of the night, but I was using Ha and [OIII] filters
so I wasn't too worried about it; I was just happy to have a clear sky after
all the rain we've had recently.

I took some more data for the Cone project and began taking some exposures
of Thor's Helmet in Ha and [OIII].

I did not get but one hour's worth of Ha for Thor but did assemble it into a
sample shot: sort of an early look-see at what may be in store.

http://www.rdcrisp.darkhorizons.org/..._thor_page.htm

I used my Dream Machine exposed through a Custom Scientific 3nm Ha filter.
The scope was my C14. I used and AO7/ST7 for guiding via an RCOS Optical
Systems Dichroic Beam Splitter.

The C14 is running about f/12.46 with the long imaging train hanging off the
back. At that slow focal ratio, I was running 20 minute exposures and took
three, which were median combined to make the image.

More results when they become available.

Richard

Hi Richard,

Gorgeous picture of one of my favourite objects! I remember panning
through a patch of space with my old 8" Discovery dob three years ago
and thinking I may have seen a slight brightening of the sky. I
dropped a UHC filter between my eye and the EP, and was struck by a
"wow" moment.

Thanks for the shot!

Cheers,

- Craig

Hi Craig.

Thanks for the comments. Thor's helmet is easily overlooked but is a very
nice object. There is a lot of interesting nebulosity in it and also nearby.
I am happy you enjoyed the shot. I hope to take more [OIII] and [SII] data
soon to make a tricolor image of it soon. Unfortunately the past two nights
were predicted to be clear but were not and the next two nights are
predicted to be raining. Maybe in a week or so?
Richard
