One of my very first images, taken from the Cosmic Campground in New Mexico in April, 2019. Stellarvue SV80 Access on Celestron AVX mount, unguided.
An impressive LEGO display at Cantigny. A wide variety of themes including the second world war, contemporary urban, and classic television and movies.
Playing around with more processing while it's too bright to image much.
Will spend the next month or two tinkering about with processing ready for a couple of months time.
Another go at M13, with guiding. still having a problem getting my field flattener to completely flatten my sc-8. perhaps its not even possible?
A few months ago I had the opportunity to photograph retired Air Force Lieutenant General Leroy Manor at Lazydays in Seffner, FL.
He shared a few of the amazing tales he has collected in his 93+ years. As a fighter pilot, he flew over the beaches of Normandy on D-Day, and years later was in overall command of the attempt to rescue American POW's in Vietnam known as Operation Ivory Coast. When asked what it was like to meet the President of the United States, he responded "which one?"

A reprocessing exercise using more frames (and less cropping!) from my data-set than my previous M13 upload as I noticed a couple of faint, fuzzy objects in the bottom right quadrant that I would like to try and identify!

The Hercules Globular Cluster, around 22,000 light years away, made up of 300,000 of the oldest stars in the galaxy and in my opinion, the most stunning globular cluster up there.
Riders took off on an overcast September morning for the 2013 Sub 5 Century Challenge to benefit the Paul Ruby Foundation for Parkinson's research.
Globular Cluster M13
Messier 13 or the Hercules Globular Cluster is about 145 light-years in diameter and is composed of several hundred thousand stars. M13 is 22,200–25,000 light-years away from Earth and is one of over one hundred that orbit the centre of the Milky Way.
"Globular clusters are nearly spherical collections of hundreds of thousands of stars, held together by mutual gravitational attraction. These beautiful objects are nearly free of gas and dust, and contain some of the oldest stars in a galaxy.
The Milky Way is host to around 150 known globular clusters, and a few more are likely to exist hidden behind the thick disk of our galaxy. The number of globular clusters in a given galaxy seems to depend on its mass: the Andromeda galaxy, our nearest big galactic neighbour, has over 400 clusters, while the giant elliptical galaxy M87 is home to more than ten thousand."
