  1. a mid-Spring reprocess Galaxy NGC 2403

    by , 05-31-2018 at 02:35 AM
    I decided to blog this post instead of posting again.. I visited the data yet again since I knew there was something wrong with it. It appears that the red channel was somehow being suppressed and possibly clipped in the previous versions. I had been using a DDP stretch in Nebulosity to start the process. This time around, I split the color channels after stacking (median to catch most of the hot pixels) and reconstructed it in StarTools. StarTools lets me boost the individual channels in a ...

    Thanks again. Here is a link that integrates what you, Bryan and I are talking about into a visual detection calculator, http://www.bbastrodesigns.com/Visual...Calculator.htm. I fully enjoy working on these solutions manually.

  3. NGC 1499 in RGB

    Indeed it is. I am going to try to tomorrow night though since it doesn't clear around here until after 8pm and the clocks have a mean streak about them tonight...

    The whole point of spending a ton of time and money on the Obsy, was to not have to go anywhere...

  4. Horsehead (B33) and IC434 - step 1

    by , 01-26-2018 at 11:55 PM
    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. ...
