The Lagoon Nebula

The Lagoon Nebula

I set up late on Saturday without knowing what to expect. Clearoutside was predicting orange conditions, Ventusky was giving me mixed signals on clouds and according to my phone we would have clear conditions till 4 AM. In the end I had a lot of clouds but most of them away from my target. I decided to go for the Lagoon Nebula, one of the lowest targets I can image. My guiding was not optimal and I had some tilt issues I couldn’t resolve but I managed to get around 2 hours worth of data.

This is a really cool nebula. It’s huge (angular size is 3 times the full moon) and there’s so much complexity caused by hot young stars, stellar winds and nebulosity.

I decided to play around with the HOO normalization scripts from Bill Blanshan and this is the result I got.

Back to deep space – the Bubble Nebula

Back to deep space – the Bubble Nebula

After a short walk in our solar system it’s back to the Milky Way.

This is a very bright emission nebula in Cassiopeia, about 8.500 light-years from us. The “bubble” is created by the stellar winds of a hot central star.

The Wizard Nebula

The Wizard Nebula

I had 3 clear nights in a row during this weekend. These are difficult times, the galaxies are fading away from us and the summer objects are still very low. I spent the nights imaging this wonderful nebula and did some work on Cygnus Wall and crescent Venus.

I also did an attempt at HOO:

The Pillars of Creation

The Pillars of Creation

At my latitude I wasn’t really sure how well this would go. The Eagle Nebula is sitting in the constellation Serpens, which for me means aiming my telescope South, which also means the glow of one of the busiest highways in the country. I managed to get around 2.5 hours of data in the end between 1AM-4AM. I might revisit this object a few times in the coming weeks and months.

This nebula is most known for the Pillars of Creation, huge towers of gas and dust, imaged by the Hubble ST in 1995 resulting in what’s probably its most popular image. Recently it was also revisited by the James Webb ST.

The dying of the light

I remember fondly how I was observing the Dumbbell Nebula last year through the 8 inch dob.

Hot summer nights, mosquito’s, dew and the dog chilling next to me. I also remember getting lost trying to find it and blaming Vulpecula for being an annoying constellation. I was happy to read later that this area of the sky can indeed be a bit confusing when you’re manually starhopping.

Shortly after I managed to take some pictures with my phone, resulting in a greenish vague fuzz. Later that year I also managed to image it with my 224MC which looked way better. The picture below is with the 533 MCP and even if I only had 40 minutes of data due to clouds rolling in, the result is very satisfying.

This was the first planetary nebula that Charles Messier discovered in 1764 and is around 1360 light-years away from us.

The Elephant’s Trunk

The Elephant’s Trunk

This one turned out way better than expected. Conditions were a bit unpredictable with only a couple of hours of 10% cloud coverage according to clearoutside. I managed to get close to 3 hours of data before a huge wall of clouds distorted my eastern views. Post processed in Siril & Pixinsight.

This region of gast & dust is 2400 light-years away from us and it is believed that star formation is happening deep in the “trunk” of this nebula.

Coma

Coma

I added a Baader coma corrector to my setup. I read a lot of mixed reviews about this one and even some horror stories about issues with reaching focus and people needing to cut off pieces of the focuser tube. It took me a while to understand I could just slide the camera + coma corrector into the focuser.

I didn’t have much time but managed to get 20 mins on the ring nebula and it looks like the coma corrector is really improving the star shapes and overall image.

Looking at the ring nebula takes me back to last summer when I was trying to image it with my phone. Summer is coming and I look forward to imaging more milky way objects. Main target will be M16!

Bode’s Galaxy

Bode’s Galaxy

Imaging during a near full moon is not really a good idea, certainly not for galaxies. This is nearly 3 hours of integration time and I had to process away some of the noise but I’m still happy with the result.

Distance to earth: 12 million light-years.

Another go at the Iris Nebula

Another go at the Iris Nebula

After my fiasco with the Iris Nebula a couple days ago (using the wrong filter) I had another try yesterday. Yet again this reflection nebula in Cepheus was proving to be a hard nut to crack. This time I had multiple issues: guiding errors, coma, camera tilt and what I believe was probably some collimation issue.

Although I did manage to get the beautiful deep blue color of the nebula, there is a lot of noise in the dust and the stars are all over the place. Let’s hope third time is the charm.
