Leo Triplet
This was an image that was posted before its time. My original intent was to get eight hours each of red, green and blue and then try some hydrogen alpha […]
Multisession WBPP
PixInsight’s Weighted Batch Preprocessing script is great for handling the preprocessing for an image acquired in a single night but doesn’t handle images acquired over multiple nights. This video shows […]
M81 & M82
Near the start of my astrophotography journey I did an image of M81 & M82 using a DSLR and a 200mm lens. It wasn’t very good though I was quite […]
Soul Nebula
The Soul Nebula is an emission nebula in Cassiopeia. It almost certainly gets its name because of its proximity to the Heart Nebula in the sky and not due to […]
The Hole In The Trees Skybox
The Hole In The Trees Skybox is the backyard observatory of Kevin Quin. Kevin was kind enough to allow me to come in and tour his observatory and pester him […]
My First Narrowband Image
Last month I finished my first narrowband image. Since then the weather has been almost entirely overcast with a lot of rain. To do something constructive with the enforced downtime […]
IC 5068
IC 5068 is a nameless emission nebula that is near the Pelican Nebula in Cygnus. This image shows just a part of it. The image is a bit over 14 […]
PixInsight Comet Processing – Failure & Alternative
When I saw that Comet C/2017 T2 (PANSTARRS) was going […]
M33 HaRGB
A few weeks ago I posted an image of M33. Then the hydrogen alpha filter I had ordered finally came in and I was curious to see what adding in […]
Rosette Nebula
The Rosette Nebula is one of the iconic deep sky objects of the deep sky. It’s also the official state astronomical object of Oklahoma. We both learned something new today! […]
Perseus Double Cluster
The Perseus Double Cluster is one of the most popular places to point a telescope for visual observers in the northern hemisphere. The sight of the two clusters in a […]
Two Years Of Astrophotography, Part 2
My second year of astrophotography was a lot more productive than the first thanks to both a change in equipment and slightly better weather. This video looks back over 2019 […]
M33
Messier 33, also known as the Triangulum Galaxy is the third largest galaxy in our local group of galaxies (behind the Andromeda galaxy and our own Milky Way). It is […]
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 […]
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 […]
