A strange Galaxy ...

M94 is a Starburst Galaxy in Canes Venatici.
Difficult to process due to the huge differences between core light and external ring.
A good series of night helped me to catch acceptable light:

I hope you'll find it interesting.

Thanks for looking and all the best,
Leo

Wow, that's amazing. Hard to believe that there are such objects out there. Very nicely done Leonardo

Incredible detail in the core Leo. Colour saturation is close to what I would call fluro but still has an impact to the overall look of the image.

Is there an outer ring? In the corners there appears to be some dust rings. Are these processing artefacts or is this an actual part of the galaxy? I wonder if you have captured something quite different.

Just out of interest I would be interested in your thoughts on using an AO over not using one?

Saturation is done high for evidence the internal arms usually unseen in other images. In the corner there's reflection from the Street lamps that enter in the telescope. I shot with 3 lamps at 20 mt. My sky is around 19.9 / 21.1 depends on who turn on the lights

For the AO .. i'm using it because i can catch the same details than the Others AP using bigger scope . When it work , for sure

All the best,
Leo

Well that's a rather pretty galaxy Leo, almost looks like a planetary nebula Great details in the central regions, a lovely portrait

Although they are relatively minor, those rings in the corners of the image do look like gradient removal artifacts..?

Uber detail Leo. You sure this is a ground based 10" RC. While I'm all for embracing colour to emphasise detail, the level of saturation and abruptness I find distracting. I'd probably tone it down a little but you're the one that needs to be happy with it. Good job.

Thanks

@Mike : the LP from Street lamps cause reflections inside that interacting with the draw tube of focuser (manually shorten some years ago) probably it lost black paint cover, i think to construction of portable shield. The flat overcorrect them. I can crop but my equipment and my sky this is ... i prefer to look to object contents.

@Jase : yes is ground based. Is the second time in 7 years i had such wonderful seeing (for me) in this condition AO work so fine. Saturation, probably i'll go backward on central part.

Thanks again to all for dedicated some of your time to see and comment.

All the best,
Leo

Lovely image, Leo! The saturated blue is just a little bit much for me too but the detail and overall impact is fantastic.

Looking forward to what you can do with the data from SRO once we're up and running there.

Cheers,
Rick.

Mighty nice target there Leo, really like your work & I like the color contrast which helps identify the galaxy & arms amongst the whole show

Leo, the sharpness of the detail in the inner starburst ring and within that, the dust lanes spiralling into the very core is magnificent. Well done.

@Rick: a lot of money for me but i hope worth the effort. I'm happy if i can take more than usually 5/6 images i taken with my RC on one year.

All the best,
Leo

I believe this is the best rendition I have ever seen of this galaxy Leo, almost Hubble details..

Hat off my friend, one of your best images and a great addition to an already fantastic collection of pictures!
