Imaging Projects

In this blog, I will share the results of all of my imaging projects. The newest will be at the top and the oldest will be further down the stack. Going back in time here is interesting - some of my early stuff was pretty rough - but I did not see it that way at the time - I was thrilled to get anything back that looked like an image! Hopefully, you will see how my work has progressed with time!

SH2-101 - A Reprocess of The Tulip Nebula - 12.8 Hours in SHOrgb

This is a REPROCESSING PROJECT for Sharpless 101 (specifically Sh2-101) also known as the Tulip Nebula. This object is located approximately 6000 light-years away in the constellation of Cygnus (The Swan). This was a 12.8-hour integration with the AP130 platform using the ZWO ASI2600MM-Pro Camera.

I was able to significantly improve the image and am quite pleased with the improvement I was able to produce - but you be your own judge of this!

NGC 6888 - A Reprocess of The Crescent Nebula ~11 hours in HOOrgb

NGC 6888 - The Crescent Nebula is a famous emission nebula located in the constellation of Cygnus. This is a reprocessing project using image data first captured in September 2022.

SInce. I have no new data to process due to the wildfire smoke, I decided to use some new tools and processes to see if i could pull more details out from the O3 shell that surrounds the nebula.

THe resulting image show much more O3 detail - including some interesting convection cells towards the bottom of the nebula

Messier 57 - A Reprocess of The Ring Nebula - 14.7 hours in LHaRGB!

Messier 57, the Ring Nebula has long been a visual favorite of mine. This was a reprocess of data that was collected in 2022. Based on 14.7 hours of HaLRGB, this data showed the rarely seen outer shell. I wanted to see if I could improve on that image with advanced tools and techniques. Since the original image was published, I created a new imaging project for posting to contain both the old and the new versions in the collection.

Messier 27 - A Reprocess of My Dumbbell Nebula Data in SHO - (10.25 Hours)

Messier 27 - A Reprocess of My Dumbbell Nebula Data in SHO - (10.25 Hours)

This imaging project is not a recapture of data for M27 - the Dumbell Nebula. Rather it is an effort to reprocess old data using new tools and new processing methods to address some concerns I had about the original image - where I thought that the stars were bloated and unsharp, and that I thought I should be able to bring out more detail in the amazing outer gas shells that narrowband imaging shows for this target.
