[edit]DescriptionM31 - the kilohour project and the quest for Oiii - Flickr - William Ostling.jpg |
After half a year of work, the Deep Sky Collective is happy to present its latest project - a kilo hour on M31. Not only does this image set new boundaries of what’s possible with collaborative imaging, its release also marks the DSC’s anniversary project! Being launched the 13rd February last year, we never thought we could achieve what we did so far - huge thanks to everyone involved in the DSC and for keeping on believing in what we do. Behind the scenes we’re working on in-depth tutorials for everyone to access - our hope is that other ambitious photographers out there can make use of these tutorials and get started in collaborative imaging themselves - helping us get started in a new era of collaborative imaging. Expect the first tutorials to be released in 1-2 months.
In our final image of M31 you see here, all of these amazing attributes of M31 can be found - a staggering 488h of Oiii integration was gathered to go as deep as no one managed before. For the Ha emissions in the background, a total of 314h of Ha integration were gathered to provide the deepest look yet. Besides the now traditional H-alpha and Oxygen III for M31, we also decided to do something unusual and get Sii - In the end we ended up with a total of 169h. The goal behind this was to 1) photograph the extragalactic nebulae in M31 in SHO and 2) check for any Sii in the arc - for our findings, refer to interesting features in our image. Finally, by Mid January, and after rejecting bad frames we ended up with a record breaking 1056h (or 1 ½ month) of integration over the LRGBHaOiiiSii channels, which marks the longest integration time ever on a single panel for any astrophoto. While the results might diminish at these crazy integration times, the effort more than paid off. Before we jump into the details of the picture, a big thank you to everyone who played a part in this project. This endeavour is a manifesto to the incredible possibilities that collaborative imaging brings to the amateur community. Working together with all of you has been a real pleasure!
