ollypenrice Posted May 7, 2013 Share Posted May 7, 2013 Another plot hatched with Dave and Zoe. This is a one night stand but with more data planned. It has just 7x10 minutes RGB and a miselry 3x15 of Ha. I also aim to capture the region North of Sadr. It's not an area I've imaged before so it was very rewarding.OllyTakahashi FSQ106N/Atik 11000/Tak EM200 mount.Oh, the Cresent might have had a bit of help from Yves' 14 inch and my TEC140.

AndyUK Posted May 7, 2013 Share Posted May 7, 2013 This is an amazing expansive area of the sky which, until recently, I never realised was so dense in signal... and I guess the only real way to do it justice is using something like an FSQ106 and an Atik 11000 ... and I do love the colour you get in your images Olly!(When you say you'll be getting the North area as well, does this mean we can look forward to seeing a beautiful RGB mosaic?)

The Ha signal is beyond belief. I thought that with just 45 minutes I'd be wasting my time processing it but I wanted the practice with the new camera's data, and I wanted to get an image for our guests as well. I'm never sure about luminance on these wide Ha targets. Increasingly I don't shoot any.Olly Link to comment Share on other sites More sharing options...
AndyUK Posted May 7, 2013 Share Posted May 7, 2013 Hmmmm - With my Sony 285 chip, I think to image even that area you've got would probably take the rest of my life... [i need a bigger-chipped camera...! ]When you say you're increasingly not bothering with luminance, does that mean you're not bothering using a luminance filter, or might you consider, in an area so rich in Ha such as this, using the Ha as luminance...(?)

Pete Presland Posted May 7, 2013 Share Posted May 7, 2013 i have nothing to add on the techical front, other than that is a great looking image! Link to comment Share on other sites More sharing options...

martin_h Posted May 7, 2013 Share Posted May 7, 2013 Nice and contrasty, can't wait to see where you go next! Plenty of stuff happening north of Sadr, lets face it there is stuff going on all over Cygnus. Link to comment Share on other sites More sharing options...

This had the Ha applied in blend mode lighten to red, a little excessively. Adding a little Ha as luminance tones down the excess of red and adds a little structural detail as well. I don't remember going beyond 15% Ha as luminance, though. This had 15%. I did try a little Ha as surrogate H beta in blue but I didn't get on with the magenta caste. I rarely do so this has Ha as red and lum only.Martin, the all nighters are coming thick and fast all of a sudden ybut your fine image has given me the will to buckle down for another one!Olly Link to comment Share on other sites More sharing options...

Martin-Devon Posted May 7, 2013 Share Posted May 7, 2013 It's a fabulous image Olly, and nice to see the Atik11000 delivering the goods now - look forward to many more in the coming weeks & months.Andy also picked up on the same query I had as well - you mention that you are not sure about the merits of collecting luminence data with widefield targets - why is this? Do they give a lot of star bloating or something? I can understand the benefits of adding HA to the Red, but does this 15% addition substitute completely for luminence? Would be nice if correct since that's one less worry when the moon is around....Martin Link to comment Share on other sites More sharing options...
