Orion's Belt and Neighboring Nebulae

CCD vs Film? Lots of time vs no patience? Alright, this is your place to discuss all the astrophotography what's and what's not. You can discuss about techniques, accessories, cameras, whatever....just make sure you also post some nice photos here too!

Orion's Belt and Neighboring Nebulae

Post by celeron787 »

Orion is one of the most recognizable constellations in the night sky even in light polluted Singapore!

View plate-solved version here: http://nova.astrometry.net/annotated_full/4709831

Three bright stars Zeta (Alnitak), Epsilon (Alnilam), and Delta (Mintaka) make up the asterism, Orion's Belt. Just to the south of Alnitak, the easternmost star of Orion's Belt, is the Flame Nebula (NGC2024) and the fainter Horsehead Nebula (IC434).

Orion's Sword is another compact asterism south of the Orion's Belt. It comprises three stars (42 Orionis, Theta Orionis, and Iota Orionis) and M42, the Orion Nebula, which together are thought to resemble a sword.

Multiple nebulae are located here which include the Running Man Nebula (Sh2-279) and M43.

Nice composition! A6000 looks a good cam for astrophotography.

Haha yes, i'm quite happy with it. Except the fact that image acquisition software doesn't support Sony cameras. I'm considering getting a modded nikon.

Wow...impressive especially you managed to catch the faint Horsehead in the same frame :)

Thanks! Super stoked to get the horsehead too, all credits to the samyang 135mm f2 lens, sucks in so much light.
Using the same data set but with 2x drizzle, I also did a heavily cropped image of M42.

Here's an old Ha image of M42 I tool last year with the ASI1600MM, with improved processing to further enhance the nebulosity.

Total exposure: 43 x 2min

I should definitely revisit this target this year hopefully when the skies are clear, and go for 5min exposures with improved tracking, more precise polar alignment and auto-guiding.

Ooops seems like the link expired, could you check if it works now?

Yup it's working. Nice image! Can't wait to see it in color!

Actually I just processed another stack of 17x 3min Ha images taken also from last Nov with the same setup, enjoy!

I guess the lack of clear skies can help improve one's processing skills somewhat haha! :mryellow:
