With the dome control back up and running, I set up for shooting, and The Rosette Nebula is turning into an old favorite. I didn’t want to stay up too late, so I only got 2 hours of data, as opposed to my desire for 4.

Once a nemesis, The Rosette Nebula is becoming a winter favorite.

Strangely enough, I’d actually shot this same object exactly one year ago, as part of a 4-object evening! Very funny to just change the year 🙂

OK, next up, I need to figure out how to shoot flats, and also I need to clean my optics. The dust bunnies are becoming my new trademark…

Edit 2/2/2017 – I reprocessed the image with flats applied. It got rid of the dust bunnies, but added some other artifacts that I needed to get rid of. You can also see that the color balance is different — my image processing workflow produces slightly random results in this area; I’ll get around to figuring it out 🙂

Anyway, I think the new photo is quite beautiful. It’s amazing to me that it’s from the same data.

Dust bunnies? What dust bunnies?

  1. The early sunset helps me get in more time without making me stay up too late, but I have to admit, I was a little relieved to see some clouds in the forecast — I’m starting to get a backlog of images to process 🙂
