Very difficult to process. In my experience to date, this is definitely a one of a kind. Different is a good thing though. :)  A little info....

 

Messier 94 (also known as NGC 4736) is a spiral galaxy in the constellation Canes Venatici. Although some references describe M94 as a barred spiral galaxy, the "bar" structure appears to be more oval-shaped. The galaxy is also notable in that it has two ring structures.

 

M94 contains both an inner ring with a diameter of 70" and an outer ring with a diameter of 600". These rings appear to form at resonance locations within the disk of the galaxy. The inner ring is the site of strong star formation activity and is sometimes referred to as a starburst ring. This star formation is fueled by gas that is dynamically driven into the ring by the inner oval-shaped bar-like structure. While you might not see barred structure, Messier 94 was classified SAB (Under the de Vaucouleurs classification system, SAB-galaxies are intermediate between SA-galaxies and SB-galaxies) because of its extremely bright nucleus. Around the brilliant circular disk is a ring of active star-forming regions, revealed in astrophotgraphy as blue young star clusters.

Fantastic Croc's Eye - well done, tough to process indeed!

Beautiful job Richard!  Great field and colors are gorgeous!  Did you add the star spikes?  I ask because when I zoom in the smaller stars seem a little triangular and I wonder if the star spike process caused that.  It's really minor but I have seen that in some of my images sometimes as well.

 

The details in the core of the Galaxy are fantastic!

Love this target!! nicely done Richard.. Especially pulling that outer shell out. I tried it with the RC8 and couldn't manage to pull it out. Great stuff

Thanks Pat, Warren, chrysalis, Goofi, and Anis. :)

 

Yes Warren, its StarSpikes Pro 4. There's little spikes from microlensing too. I hate those. :(

Wow, Richard. That is phenomenal! I love everything about this image. The color is excellent, the detail is very well preserved. The depth, just amazing. 

 

This is IOTD material right here! :)

Thanks for the very kind words Jon. Too kind I think. :p  It was really difficult. When I added my Lum to the color, it looked like I had no color. I ended up going 50% Lum, saturating, adding Lum again at 75% and saturating, etc.

Great work Richard.  I really like the color tones you get in your images.   Everything looks very natural.   There may be a bit of purple hanging out in some of the stars on close inspection (more so on the left of the frame). 

 

The detail is great and the residual noise texture is actually very pleasing and natural also.

Thanks Jason. Yes, I saw that. It was a struggle boosting the blues. When I removed purpleish fringes it was very bland looking. It honestly looked like I had no color at all when I first added my Lum to the RGB. It could be things arent lined up perfectly, I dont know. I just know it was a struggle. This image was an IOTD from early May, and it looks like he had similar issues. Its definitely an oddball, but fun and interesting to process. :)

Interesting, has anyone ever tried Tone Mapping with an LRGB image of a galaxy?  I've only used it on SHO Nebula images.

Well, I'm not as big a galaxy guy as many in this forum. However, for some reason, this one I really love. It is not wildly saturated, yet it is still colorful. It feels more "accurate", which appeals to me. It is a deep exposure, and you know me and faint details, you can see so many faint background galaxies. 

 

Anyway. Well done. :) Especially if you found it a challenge. Very interesting technique with the double lum combination. That is something I have always found difficult with galaxies (which I am TERRIBLE at processing), so I may have to try that in the future.

Beautiful job Rich!  I don't think all galaxies do as well with the wider view, but this one does great with it.  It's just like a beautiful glow hanging in space.  A whole mess of stuff hanging in the background here too!  Thanks for sharing!  I'm so torn on the spikes.  I got Starspikes Pro too but haven't found one I wanted to use it on yet.

Thanks Madratter & Josh :)

 

Josh, I'm working on an open cluster right now and feel it adds so much to it. It looks very plain without the spikes. I'm a bit torn as well, but think used in moderation it adds to some images. Myself and Lloyd both complained about "that darned star" in our NGC 5033 images. I just added spikes to it and think it looks much better. I'll probably post that revision after supper tonight (yeah, we're eating late :p ). Another thing thats nice about it is enhancing the spikes in images using an RC or newt. I re-worked an old M101 that I shot with the RC and thought it looked nice.

I personally love the spikes.. that is one thing I am going to miss moving from the epsilon to FSQ..

I like adding spikes to certain stars but sometimes they can get overwhelming, I think thy work well in this image.

Do you have PS? You can always add StarSpikes Pro 4. :)  You have maximum control over them. Seems to be a pretty powerful add-on. You can control the angle, saturation, quanity, intensity, length, as well as some secondary effects and rainbow frequency and intensity.

Quite nice.

 

I would love to see a 100% crop of just the galaxy.
