1. Horsehead (B33) and IC434 - step 1

    by , 01-27-2018 at 12:55 AM
    Thanks Steve. I decided to blog this post since I don't have new data from that I took a week ago. The moon is too near this target to bother setting up in below freezing weather.

    I actually used very little noise reduction on this. I was able to determine what was going on with my Pole Master and have since setup a few times and very quickly polar aligned. I want to aim for this one at least one more time this season.. I need to look into a tree surgeon to take care of a few ...

    Thanks! I do too. The SNR was already very good with the data that I have. I am busy this week, so it may be the next dark cycle that I can go for a spin with her. I didn't lose any subs in the process and had no star-trailing.

    The focus was significantly improved compared to past efforts, though I might be able to find some that I could add to it.

    I ended up stretching the color channels separately using Fits Liberator (a Nasa product), which worked very well. ...

    I'm just not used to it any longer. This coming Saturday is expected to be up to 52F (11.1C), which is a big swing. I used to live near the border with Canada (~32 years ago) and we often saw temperatures of -10F (-23.3C) in December.
  4. The Iris Nebula (NGC 7023) (a single night)

    Thank you Jerry! This will be helpful as I try again. 99.9% of my imaging for the last 1-1/2 years with the Atik have not included flat frames, so I am interested in how they might improve things. I enjoy the impact they bring to my DSLR work.

    I use a LED light panel together with a t-shirt over the OTA normally. The DSLR easily adjusts to this. I found the issue described regarding the camera shutter too. I wasn't able to dial in SGP to do this well; the Flats wizard was ...

    I just saw the blue halos on some of the stars. It was not apparent on my computer at home, possibly due to the gamma differences with a PC vs. Mac. I would dial that back given the chance.
