This is one of the first images through my new Esprit 120. It is the hydrogen alpha data and was taken on Dec 19, 2015. My intent was (and still is) to obtain SII, OIII and RGB data on this target but our winter weather has been so bad that this has not been possible. The target is dropping now and my next opportunity will be in the fall.

I thought I'd try something different this time but still using the base SHO (Hubble) palette. A bit of artistic license you might say.

Each year since 2021 I try to take at least one night of exposures of the Orion Nebula, but the final picture I made this year is by far the best one I've ever made. It's also the first time that I was able to see the 4 main trapezium stars in the core and a small protoplanetary disc slightly to the right of it (between the two bigger stars). This result motivates me to take an even better picture next year. Maybe with at least 10 hours of data? Maybe also use my dualband filter? Who knows, lets see what will happen. For now I hope you enjoy this picture as much as I do!
The western portion of the Veil Nebula in Cygnus (NGC6960).
I've reprocessed data taken in 2012 to include this image in my forthcoming book on astrophotography.

I'm excited to share this one with you! This target (IC 443) was on the top of my to-shoot list when my camera broke in early January... so when I got the loaner-camera, I started working on it. It took me 4 separate nights of shooting to get the full amount of exposures I was hoping for with this one, but I think it was worth the wait.
The end result came from about 8 hours of exposures, hand-selected from about 16 hours of candidates). The Jellyfish nebula currently sits above Orion's left shoulder in Gemini. It is a supernova-remnant that is about 5,000 light-years away. The bright star is a red giant named Propus. The colors are a little different and interesting, here! This region emits largely in the Hydrogen-alpha (H) and Sulfur-ii (S) part of the spectrum, which give it the reddish-orange hue you see here in the Hubble palette. There's just a bit of Oxygen-iii (O) which outlines a few parts in blue. The Hubble palette means mapping SHO to RGB. I've said more about it in other posts when I describe my narrowband-imaging process.

This is my current imaging setup with the Star Adventurer and the ASI1600MM-Cool.
Still tuning it, but it should work well once I'll receive the rings and dovetail.
The guiding scope is an Orion 50mm mini guider and the camera an ASI120MM ST4.
The tripod is a Manfrotto 535, very sturdy and light, perfect for this setup.

Observing Notes:
I’ve been having poor results over the last three months due to inaccurate star alignments. This night was no different and I also had issues with a loose lens on my Polemaster and the guide scope did not want to operate.
Spending all evening dealing with technical problems on a field night was disappointing and this shot was a last resort quick snatch of 36 frames, so as not to go home without at least one image. I was not even sure exactly where I was aiming and had to subsequently identify the objects in the frame.
I’ve had two observing sessions at home since then and with the alignment very erratic I need to find an opportunity to take the scope in for maintenance. So no more sessions for a while! 😦
