Hi all,
I have gotten around to processing my data for the Rosette Nebula. I think its come up OK, I could probably stretch the data some more. This one has been done in Gimp but I am now trying to get my head around StarTools so I am keen to process this one again. I need to get onto doing Dark Frames and fixing up some satellite trials. Coma is quite bad, but I have since spaced it out so its better (not yet perfect).
It looks like i might have that red hue again as per recommendations in my other post. I am white balancing on a corner but it looks like i might need to pick a spot further in to get the RGB to line up correctly.
Equipment
Equipment list is as follows
Skywatcher EQ6R-Pro
Skywatcher 130P
Nikon D5600 (I've removed the stock IR Filter)
ZWO IR Cut Filter
Baader Coma Corrector
Guiding I'm using a Skywatcher 9x50 finder scope that i made up a sensor housing for with an IMX291 sensor
Acquisition
Capture details were as follows (Using BackyardNikon)
60 x Light Frames 360 seconds @ 200 ISO
I used a master BIAS & FLAT set when stacking. Flats could've been better by the looks of it.
Stacking
I have used DSS to stack the images
Processing
Post stacking I put the image into gimp, cropped & scaled it. Stretched the levels > white balanced the levels > did a star reduction by fuzzy selecting the stars and using the value propagate function > performed some curve adjustments > removed gradients > added a little bit of saturation > final white balance tweaks.
The same as my other post. Any comments/feedback would be much appreciated. Would love to improve where I can.
I thought I'd upload this one to AstroBin so i could include a higher resolution image. Link available here
