Rosette Nebula

Post by Europa » Mon Mar 05, 2018 10:30 pm

I shot this over a few days +- the full super moon. 68 images of 180 seconds with a QHY12 OSC on Celestron RASA. I’m having some problems with coma that I’m trying to work out...so I did some star “fixing”. Added some diffraction spikes to break up all of the red in the photo.

Nice! It is a bit RED but it looks good. Does longer exposure make it redder? Nice to see some one is getting to get some sky!

Thanks. The longer exposures just blow out the stars. At least with the RASA, I’ve learned to expose long enough to get the histogram just barely off the left side, then reduce the exposure time slightly.

Yeah it looks good but you might want to dial back the contrast. Don't force the image. Just keep adding data if you need to. Really nice job.

Thanks for the suggestion, I do tend to over cook my images. I need to get in the habit of stepping away and finish processing the next day.
