Horeshead Nebula - Ha

[swlloyd3]

Hello,

So the skies cleared for a good period last night and a finally got to try out my modded EOS 1000D and the 12nm Ha clip in filter!

Targeted the Horsehead nebula as I have never imaged this before. I also completely forgot to take some shorter exposures for the Orion nebula so apologies in advance for the badly blown core! - hopefully I can get some shorter exposures soon to add + correct the core.

Two versions  - first is the full wide frame and the second is a smaller crop which was 2x drizzled in DSS.

Mount: Astrotrac

Lens: Nikkor 135mm F2.8 @ F4

Camera: EOS 1000D (Modded)

Accessories: 12nm Ha filter + botched dew shield

Photo details: 16 x 5 minutes lights - 16 Darks - 42 Flats // ISO 1600 // F4 //

Wonderful shot. Well done.

It may be with your Ha filter that some detail in the core remains. Try carefully masking the area or cheat and use the history brush as you up the curves.

cracking shot - even managed to get a bit of Barnards loop in there too

Thanks for the comments

I found an old Orion nebula I did through a Megrez 72 - here is the combined result.... Quite tricky to combine but I think it looks ok if you don't zoom in!!

Nice to see an old favourite in very wide field like this - excellent

very nice. Looks like the filter is a good way of controlling Alnitak as well.
