Quote:Looks like you had some good data. I took a similar picture with my ED80 too! Look up how to do background neutralization/color calibration with whatever software you're using. I think you might have clipped the black point which is why it looks 'too' black. Just remember your skies aren't black! Thanks for sharing with us.
Quote:Forgot to add, most of my shots are at ISO 80 and I used one image that was filtered with an Astronomik UHC and one image filtered with orion OIII filter. I just stacked all as light frames using dss.

Quote:Jeff, I did some reading on star tools. Pretty excited to try it.Topher, I love the k5. Your image @ISO 6400 looks really good. What's the time of the exposures and did you use flats or darks? As far as ISO 80, I thought it had the best signal to noise ratio, widest dynamic range, and lowest readout and amp noise. I am surprised by your comment but still learning. Great shot of m42!
Quote:rflinn68 is your image done using Scott Rosens LLRGB?
Quote:Topher you have convinced me to try ISO 800. I actually don't know how to get ISO 1200 on the K5. If anything,800 will greatly reduce my sub times. Also, if I start shooting higher ISO, I will have to learn how to do darks and flats. I figured that at low enough ISO, I wouldn't need darks. Also, do you know if the built in High ISO NR (dark F subtraction) is a substitution for stacking darks on DSS? PS. I am glad I posted on this site. I am getting so much info.
Quote:ISO 80 does deliver the best dynamic range, which if thats what you're going for then its the best place to be. Just make sure your histograms are in the right place so you're not clipping any data. However, the best SNR has been found to be at around 1200ish for the Sony sensor thats in the K-5.
