Bringing Your Time and Effort to Life

You’ve just spent hours, or even days or weeks collecting data for your latest object. You stack up all of your light frames with your calibration frames (darks, flats and BIAS) in DeepSkyStacker and let it do it’s thing. What comes out is a very dim view of your object, or a even what looks like a red hazy image with no object at all. If you did the first part of the job right, your data is in there, I promise.

However, there are methodologies, workflows, and tools to help you along.

It’s probably something the size of a grain of sand skipping on, or burning up in the atmosphere. It just happened to be exactly in the middle of my frame.

64-bit Deep Sky Stacker (DSS) is Here!!

Version 4.2.1 is out now and has many speed enhancements over the initial 64bit release (link at the bottom).

I stumbled upon this last night after not imaging for a couple weeks due to weather. There are no release notes on the version, but I’ve been waiting for this since I started, so I went ahead and downloaded it. So far, so good. The look and feel are basically the same with only slight visual tweaks.
