Monkey Head Nebula - NGC 2174

#1

Post by STEVE333 »


It was a pleasant surprise to see this nebula had strong emissions in the Ha and Oiii wavelengths. Fits perfectly with the Astro Duo-Narrowband filter. The night was extremely wet with humidity, and, everything was dripping at the end. Fortunately a small towel over the active USB cable connections kept them dry, and, the Dew Heaters kept the optics dry. The new setup with the laptop inside the house is working perfectly, and, has been a nice change for the better!

Looking forward to purchasing a cooled camera, filter wheel, and, NB filters and getting started in NB imaging. Till then, the Astro Duo-Narrowband filter is the best I can do.

Thats a wonderful image Steve. Even the cropped version has great details.

Great work with 3.5 hours of exposure.

Wow, you are going to make the jump to nb imaging. Best of luck with that. I’m sure that you will be producing even more impressive images soon. Your current work with the Canon has been remarkable.

Thanks Jim, I appreciate your kind words.

I've finally decided to make the change to cooled NB imaging. I see all the beautiful NB images and I see the halos from reflections with my current filters. So, lots to learn: which cooled camera to get, and, what software to control that, a filter wheel and something to control that, and which filters to get ($$$). At first I was overwhelmed, but, lots of good information on the internet to help. I've already learned how to have laptop A in the house connected to and controlling the mount/camera/filter wheel via Ethernet while I take Laptop B outside to the mount to perform the Polar Alignment while watching the laptop A screen on laptop B outside. Pretty neat.

This is certain to be a journey, but, at least I'm started on the journey.

I know that it sounds like a lot, but I’m sure that there is a lot of excitement thinking about upgrading and the challenges that go along with it.

I will miss your superb dslr work!

Another fine image, Steve. I'm sure you will do as well if not better with the NB processing. Looking forward to going along for the ride vicariously.

Steve that is an outstanding image! :Clap:

I was able to pick this one up visually with the 12 inch from our suburban backyard, albeit weakly. The O-III filter definitely helped.

I will add that unfortunately many sources identify the main nebula as NGC 2174 which is incorrect. What we know as the Monkey Head Nebula is actually NGC 2175, which consists of the emission nebula + the open cluster OCL 476. NGC 2174 is a small knot within the larger complex. There is another catalogued bit around the brightest star in the cluster, HD 42088, known as IC 2159, though some folks question it as a distinct object and I admit I've had problems discerning it in the many images I've looked at. Then along the eastern side is a cluster of stars sometimes referred to as NGC 2175S, but is also catalogued as Pismis 27. I have annotated your image below with these various parts. Thanks again for wonderful image. :)

Thanks for the clarifications Alan. Your knowledge of the classifications and identifications is much appreciated. Thanks also for the annotated image.

Congratulations on your being able to see these things visually. I never view through my telescope anymore. In fact, I leave my camera attached to the telescope so that I can use the same set of Flats multiple times. Saves me a lot of time/effort.

I certainly understand that if someone images 100% they would leave that equipment married to the scope all the time. Makes perfect sense. As I don't have an interest in actually doing imaging myself, I live vicariously through the efforts of those who do! :)

I do enjoy looking at images and seeing what I can discern in them. It helps me keep my eye sharp for visual observing. Plus I do a lot of research on object identification/classifications and their histories.

Great image and a. very worthy AOPD. Honestly that's the first time I've seen why it's called the monkey head- could never see it before. Of course now I'll see it in every image of that area.

Excellent image and crop Steve. Nice to hear your inside laptop is working well for you. It's tough to have heard your laptop stolen, but maybe it leads to a better setup with the computer inside.

Congrats on the Photo of the Day!
