A very short Horsehead Nebula

Recommended Posts

Cloud dodging most of last night. I was trying to capture some Ha for M33 and left the kit outside for the cloud to clear.

I was partially succesful and noticed Orion rising above the tree line so I waited a while longer and started 15 min subs on B33 through a Baader 7nm Ha filter.

This is only a stack of 2x15 min subs from 8; I had to lose 6 to cloud (that was painful I can tell you :angry5: )

Not much processing on this to be done, quick levels, slight curve lift and a large high pass filter/blend overlay.

I keep looking at it thinking 8 x 15 would have really started to smooth things out and bring out some detail. I'll start this target again when it gets a bit higher for me.

It's been a bit of an imaging Nemesis of mine over the past couple of years; that and M33 :).....oh and M31 :) :)

I suppose I am saying it still looks like a faint object in space rather than a bright red cloud in space.

I know what you mean Shane, the horsehead is one of those targets which can actually look better in mono, it is certainly easier to pick out the clouds and details.

Nice one Simon, the long subs have definitely paid off here, hopefully you can get more, Alnitak is nicely tucked out of the way too :)

Thanks for the comments :)

I'm keeping this mono and with the same fov. I'd like to get a few hours on the horse to smooth things out but also start fetching out the details in the curtain. Shame about the flame but I want to keep Alnitak out if the way :) The 16hr let's me do that quite nicely.

The longer you can go with Ha subs the more detail you will get in the darker regions, and the more contrast in the lighter areas. If you can stretch to 20 mins or more you'll see a difference again.
