M22: The Great Sagittarius Globular Cluster
Messier 22 (M22) is a globular cluster in the constellation Sagittarius, located about 10,000 light-years from Earth.
I recently started taking Adam Block’s DeepSky Academy course. I highly recommend it.
This astrophotograph is the result of the “Stars and Star Clusters” workflow from that course.
I stacked the RGB data provided by Adam Block and processed it in PixInsight.
Lifelong learning is very important to me, and I enjoy staying up to date on the latest astrophotography processing techniques and in all sorts of other areas.
The desire to keep learning is like fuel for my brain.
How about you? Do you enjoy taking courses (whether related to astrophotography or not)? Maybe you’re taking one right now?
Clear Skies!

I took about 50,000 photos through a 14" telescope last night to produce this: A hyper-detailed photo of the full moon. The fidelity of the photo was great enough to allow me to greatly enhance the color, revealing a hidden world of geological diversity.
Humanity’s orbital outpost and our moon. Can you spot it???
Captured at 1:56:41 a.m. EDT from Florida's Space Coast, the @Space_Station and her crew of 7 were seen crossing the disc of our moon.
On board are @NASA astronauts Jessica Watkins, Luke Delaney, and Anil Menon; @csa_asc astronaut Joshua Kutryk; and Roscosmos cosmonauts Pyotr Dubrov, Anna Kikina, and Sergey Teteryatnikov.

This is one of my telescopes, and it’s my first “real telescope” (before this, I had another small telescope years ago, which was practically unusable and therefore rather disappointing).
I’ve taken most of my photos with it, including lunar, solar, planetary, and deep-sky astrophotography.
The four astrophotos were also taken with this Newtonian telescope.
I’ve owned it since 2017 and still enjoy using it to this day. This Sky-Watcher telescope offers pretty good value for the money.
Over the years, I’ve upgraded it with, among other things, an automatic focuser from Baader Planetarium, the 2" BDS-NT Diamond Steeltrack Focuser (excellent focuser => no backlash!), a 3D-printed primary mirror mask, and a mirror heater for the secondary mirror.
In 2019, I switched from a Sky-Watcher NEQ5 mount to a sturdier mount capable of handling a heavier payload, the iOptron CEM60 (see photo).
I still use the Sky-Watcher NEQ5 mount for my smaller telescopes.
I purchased this telescope equipment, with the exception of the 3D-printed primary mirror mask and secondary mirror heater, from Astroshop.be (formerly: AstroMarket). I’m not being paid to promote them, but I do want to emphasize that I’ve always received high-quality service from Astroshop.be.
Hopefully, we’ll have some clear nights again soon so I can get back to using this telescope setup :-).
I’m really looking forward to spending time under the starry sky again.
Do you have a favorite telescope?
Clear Skies!

Mineral Moon - Waxing Gibbous Moon 89%
I stacked 50 frames of old data from the waxing gibbous moon phase and processed them in Affinity V3 to create this mineral moon.
The images were taken with a Canon EOS 750D DSLR, paired with a Sky-Watcher Explorer Black Diamond N200/1000 (Newtonian telescope), mounted on a Sky-Watcher NEQ5 mount.

Zoom! 🧐

This picture has never seen a desktop. Data beamed directly from the #Vespera II telescope onto my iPhone and slightly adjusted in the incl. SkyColor app.
Why am I showing you this?
Well, this is a refreshing approach to dive in the deep sky. It eliminates the need for special software, a powerful computer, advanced skills and a lot of TIME.⏳🔭

NGC2419 star cluster I shot for 108 minutes. It's 300,000 light years from us.

I'm pleased to reveal my 150 megapixel photo of the Lagoon nebula, captured with a 17' telescope over several weeks this past summer.

☀️ Thursday, October 22, 2026, and the Sun is still crossing Virgo, where it stays until the very end of the month.
Through the filter this morning I counted two sunspot groups: a busy little cluster of four dark spots and a lone spot sitting further out toward the edge, which line up with NOAA's active regions AR4557 and AR4560. The big AR4551 that kept firing flares last week has just rotated around the limb to the far side, so the disk looks a lot calmer today.
Quiet days like this remind me that our star never really sits still, it just takes a breath.
⛔️ Never look at the Sun, not even for a second, without a certified solar filter in front of your eyes, camera, binoculars or telescope. Permanent eye damage happens instantly and without pain.

I used a 14” telescope in my homemade observatory to capture Saturn and Tethys, one of its moons.
You can see spokes on the rings, my first time capturing them so vividly!

It was a "see Charlotte from the Blue Ridge Parkway" kind of day.
Crystal clear visibility, you could even see it with your naked eye.
