I recently added a Ha filter to my collection and promptly put it to the test by soaking up a decent amount of data on the Horsehead nebula. I wanted to improve on my initial attempt on this target from 2014. One of the issues was that I'd like to show the delicate 'curtain' structure of IC 434, the bright glowing hydrogen emission that the Horsehead is silhouetted against.
This also prompted me to add more data to the LRGB channels as well in order to bring out the faint dust details better, so all together with last year's data I ended up with over 26 hours of data which I completely reprocessed and assembled into this updated version.
I'm pleased that the result has higher resolution and more depth than last years' effort. The colours are also richer and more refined and in particular the Ha curtains now stand out above and around the Horsehead.

About the image:
The Horsehead Nebula (also known as Barnard 33) is without doubt one of the most recognized and fascinating objects in the sky. This iconic feature is formed by the sharp outline of a dark dust cloud, with a remarkable likeness to a horse's head, silhouetted against a brightly glowing patch of ionized Hydrogen (IC434) that is being energized by the hard ultraviolet radiation from nearby Sigma Orionis, a...

Barnard's Galaxy Deep Field - 29.5 Hours - From Rolf Wahl Olsen - https://flic.kr/p/23av3gA

This image shows a deep view of Barnard's Galaxy (NGC 6822), an irregular dwarf galaxy that is one of the nearest neighbours to our Milky Way. This galaxy was discovered by astronomer Edward E. Barnard in 1884 and is located about 1.6 million light years away in the constellation Sagittarius. Despite boasting a meagre 10 million stars, and extending only one tenth the size of our Milky Way, NGC 6822 contains a full menagerie of hot red star forming HII regions, planetary nebulae, bright OB associations and dark clouds.

In 1925 the famous astronomer Edwin Hubble published his paper 'N.G.C. 6822, A Remote Stellar System' which was a detailed survey of this galaxy. Apart from describing five of its brightest HII regions Hubble also discovered 11 Cehepid variables in NGC 6822. This was one of the most important discoveries in galactic astronomy and enabled NGC 6822 to be the first galaxy beyond the Magellanic Clouds to have its distance measured and in turn greatly expanded the size of the known Universe at the time.

NGC 6822 is a challenging galaxy to photograph since it has a very low surface brightness. But still many of its brightest stars are resolved together with the various star forming regions and blue OB associations.

Also visible throughout this image is a thin veil of wispy filaments, similar to high altitude fair weather clouds. These ghostly structures are now known as galactic cirrus, or Integrated Flux Nebula (IFN). Only a few decades ago such structures ...

Robert Bloch's tales of terror lead a fine cast to their death in a cursed house of doom. Cushing and Lee lead a fearfully good third Amicus anthology. 1971

‘What is already an innovation gap could become an innovation chasm.’

Large pharma companies withdrawing from R&D for infectious disease therapeutics has a growing impact on non-profit medical research orgs like DNDi, writes our R&D director in @statnews.com.

Pharma’s shift away from infectious disease research could spell disaster for the world’s poorest people

The number of “innovation champions” in the pharma industry working on infectious diseases is dropping — and that’s troubling, writes R&D director for Drugs for Neglected Diseases initiative.

1st chance to check in on Hornets since before the storm. Still very active with a few dark morph individuals, such as this stunner, showing. Reading up it's natural colour variance.

Cryogenics turn deadly when the best of intentions go bad. Smart, tautly directed and strikingly shot. Engaging chiller with Karloff in terrific form. 1940
