Two Years of Astrophotography, Part 1

In March of 2018 I finally began attempting to do tracked astrophotography. That is, using a tracking mount and a camera to take multiple images and combine them in the […]

Determining Offset

In the last video we talked about how to determine what the optimal exposure level was. That method depended upon knowing what your cameras exposure offset is. If you don’t […]

How To Determine The Optimal Subexposure Level For Astrophotography

Many beginning astrophotographers are confused about how long each of […]

Cocoon Nebula

This data actually is about six week old at this point. It was challenging to process and I was hoping to get more but six weeks of clouds have pushed […]

Pelican Nebula

The Pelican Nebula is located just off the “east coast” of the North American Nebula in Cygnus. It is an emission nebula about 1,800 light years away and has an […]

Eastern Veil Nebula

The eastern veil nebula, NGC 6992, is part of a supernova complex known as the Cygnus Loop. The entire loop is quite large covering more than six degrees of sky […]

Propeller Nebula

The propeller nebula is one of the few deep sky objects where it is completely obvious how it got named. The “propeller” is clearly visible in the center. This is […]

IC 1396 – Elephant Trunk Nebula

The Elephant Trunk Nebula is a very large emission nebula, actually larger than my field of view. I would need to do a mosaic to fit it all in which […]

NGC 6888 – Crescent Nebula

The Crescent Nebula is an emission nebula in Cygnus a couple of degrees from the star Sadr, not far from the region in this image. According to Wikipedia, its shape […]

M16, The Eagle Nebula

This was my first and perhaps only image from the Almost Heaven Star Party. I attended AHSP last year for the first time but it was cloudy or rainy for […]

The Astro Imaging Channel Workshop

I was honored to be invited on to the weekly YouTube program, The Astro Imaging Channel, to do a short presentation on how I processed M13 data that was made […]

PixInsight Processing With Flat Darks

This is a presentation I put together for a member of our local imaging group on how to use flat darks when doing image calibration in PixInsight.

PixInsight Mask Creation

This was for the September 2019 meeting of NOVAC’s Byron Bergert Imaging Group. It is a basic introduction to mask creation in PixInsight.
