Hi all,
This has been a rocky year for me. I have quite a few unfinished projects in the works. I either have images with less exposure time than I'd like, and/or images that I consider incomplete for one reason or another, or images that I just can't seem to get right. Maybe it's the perfectionist in me.
Anyways, here's an RGB that I shot of the Lagoon/Trifid nebulae. This was shot last June 9-10 at a local park/dark sky site. This data is part of a collaboration I am having with John Noble: I shot most of the RGB data, and he shot H-alpha data. The RGB data alone looks pretty good, so I decided to share it anyway (I hope you don't mind, John
This is an RGB of 45 minutes each channel with 5 minute subs.
Camera: SBIG STL-6303
Scope: Takahashi FSQ-106
Mount: Takahashi EM200 Temma 2
MaximDL used for acquisition, calibration, alignment and stacking
Photoshop CS used for final processing
I averaged the aligned and stacked RGB data to create an artificial luminance for this image; that seemed to smooth the data out a bit.
I've hemmed and hawed about the color balance. One big hint is that the cloud of stars between M8 and M20 in the image had a green cast
to it, which I processed out but maybe at a cost of real data? I'm not 100% sure I have it right. What do you think?
1/3 sized image attached.
