April

April

We’re deep into galaxy season now and by 3 AM the summer triangle is already visible. Conditions are typical for April, lots of high clouds and some pockets of clear sky mixed with rainy days.

I’ve decided to add another item to my collection, the Samyang 135 mm lens. This is a true classic among astrophotographers and I’m looking forward to use it. I should get it on time to start imaging some targets in Cepheus hopefully.

At the same time I’m also wondering about finally getting a true galaxy scope. I’ve been thinking for years about this and for a moment I considered getting a proper refractor or even a C8 but in the end I might settle for a bigger newtonian. It comes with a lot of babysitting and tweaking, but I don’t think you can beat the aperture & speed for the price of a newt. We’ll see, it’s something for next year.

In the meantime, my 130 pds is still going strong. Here’s is the Cocoon galaxy, about 5 hours of data.

I find one of the most striking features to be the star formation regions withing the stellar stream that connects these two interacting galaxies. It’s mind boggling that we can see this bridge of light between two galaxies located 25 million light-years away.

Globular clusters

Globular clusters

Last year I had a quick look at M3, one of the best looking globular clusters in the Northern Hemisphere. I knew i had to revisit and here’s the result of about 6 hours of integration time.

These balls of light are fascinating. They’re extremely old, have all types of exotic stars in it and might be the remnants of older galaxies.

Globular clusters reveal a lot of interesting stars too. M3 in particular has a very large population of RR Lyrae stars, these are variable stars with very visible pulsation periods.

The video below is a compilation of multiple 1 hour stacks. It still needs some work but you can see multiple stars appearing, disappearing and even changing color due to their variable nature.

Early spring galaxies

Early spring galaxies

Another set of clear nights under very pleasant temperatures for the time of the year.

I managed to get +/- 12 hours on two targets. The first one is the interacting pair of galaxies NGC 4656 & NGC 4631. The second one is the very faint NGC 4236 – of the bigger galaxies (in angular size) in the Northern Hemisphere, but extremely faint so it’s often overlooked.

I’m very happy with both images as they fit nice in the field of view of my scope and even if I’m still not perfectly collimated, the end result is just fine.

Clouds are back now and the moon is up, so it’s time for a little break I guess.

Leo Triplet

Leo Triplet

I had a couple clear nights in a row but the weather behaved very unpredictable with a mixture of high and low clouds coming and going and some fogg to top it off.

Over three nights I struggled with collimation and by the time I had it right my subs got plagued by windy conditions. In the end I managed to get about 5 hours on the Leo Triplet and I was really surprised by how well it came out. This shows again it’s always worth setting up, worst case you learn something about the sky conditions.

It’s getting a bit warmer now so let’s see what that means for imaging conditions in the next few weeks.

OBAFGKM

OBAFGKM

I like watching stars so here’s a little journey to the brightest stars using the OBAFGKM spectrum.

From Alnitak (the hottest and bluest) to Betelgeuse (the coolest and orangest).

M106

M106

First galaxy of 2025. I’ve always struggled with this one. The challenges are to bring out the detail of the core, getting some structure in the outer arms and battling the bright stars outside of the frame. But I really like the final result.

I also think I have some collimation issues but I hope to solve these in the next few clear nights under the full moon.

Scope maintenance

Scope maintenance

The last few weeks I’ve been pondering about getting another scope with more focal length but in the end I’ve decided to stick with my 5 inch newt for now. I do plan to perform some upgrades, so I’m looking for a better focuser and I might even replace the full metal tube with some carbon material.

This should be an interesting project, let’s hope I don’t break the scope in the process.

In the meantime, the SQA55 did some work on the Orion Nebula. This has been an amazing purchase and now it will get some well deserved rest.

Horsehead continued

Horsehead continued

In the end I did have some extra clear skies to finish the Horsehead project. I still think this one looks better with a broadband filter but with an 80% moon phase and Orion dropping very low in the early morning I have no choice but to continue with duoband.

I might have some more clear sky tonight so I will have a go at the Orion Nebula.

The Horsehead Nebula – WIP

This is one of the most iconic and well known DSO’s, famously discovered in 1888 by Williamina Fleming. I collected about 5 hours of integration time on this target but had to throw away about 3 hours. I believe this target deserves at least 10-15 hours so I’ll park it for now and revisit next winter.

The Jellyfish Struggle

The Jellyfish Struggle

I’ve been trying to get a proper image on the Jellyfish Nebula for a while now. This supernova remnant in Gemini is probably my favorite deep sky object. I did capture something last December which I shared here, but the session was plagued by high clouds and I was never really happy with the final result.

I tried two more sessions this year with my 130PDS in November but I had the same issues with high clouds. 

The sudden appearance of clear skies in the last weeks gave me another opportunity though. I decided to take no risks and go for the widefield approach with my SQA55 and I am happy with the result. I still feel I might revisit this one at some point with a SII filter to bring out some of the green of the nearby nebula.

2024 has been an amazing year for my astrophotography. It started rough with only a couple cold clear nights in January but really opened up by April. In total I managed to work on 38 projects with many of them exceeding 10 hours total integration time. 

I also managed to get some pictures of objects that were really high on my bucket list such as the Twin Quasar, TON618,  brown dwarfs, the Trifid Nebula and the Helix nebula. 

I need to prep my 130PDS now for galaxy season and as I said before I might look at upgrading to a bigger refractor in the near future. No rush though, the universe is not going anywhere anyway.
