What object in the sky always bites you in the ass when you try to image it? Endless cloudy nights, dew problems, focus issues, equipment failures… A lot of us have one object that continues to elude us year after year. We look on Astrobin or Instagram, see everyone’s beautiful images of this object and want to tackle it ourselves, but every time out the Gremlins start to work their way into our imaging session. I wouldn’t rush to say that everyone has some object they just can’t seem to capture, despite good planning and preparation, but I’m sure there are a lot of us out there with one object that just pisses us off, night after night and year after year.Read more

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. How do you pull that data out in the most effective way possible? Well, I’m sorry to say there is no magic bullet because everybody’s data is different. However, there are methodologies, workflows, and tools to help you along.Read more
