The data for this image is NOT all mine, but a collaborative effort between three friends: Al Howard, Eric Zbinden, and me. I did the processing of the data for the version you see here.

Eric, Al and I often meet at dark sites to do imaging, so we had this fun idea of all of us targeting the same object, but each of us using different filters.

Eric took the Ha data. Al took the luminance, and I took the RGB (color).

To make things more fun, each of us was shooting with a different telescope and a different camera. Al used a QSI583 camera on a NP101is scope, Eric used a FLI16003 on an AP155, and I used my STL11k with the FSQ106.

While the resolutions from each of our scopes/cameras aren't brutally far apart, they're definitely not close. Add to that the nights we captured the data were rather bad - the first night none of us could get more than one hour because fog rolled in, then on the other nights, transparency was really bad... Yet I think the image came out rather ok.

Stunning vista! One of my favourite regions of the sky, all the colours and swirls make a really magical picture! My favourite will always be Tom Davis's widefield and Russell Croman's closeup.

This did come out amazingly well , I had forgotten about this and seeing the raw data that night I hadnt seen it since.

I remember this was the shot you guys all did that first night from the airport and the fog skunked us.

Looks like we picked a good one to ask you up :)

It is a fickle hobby sometimes.

Erik - yup... We started it at Bonny Doon that night, when you, Paul and Mark were there (I'm not sure if I'm missing somone). First time at BD and fog came to greet us. Funny hobby indeed :-)
