Ultra Deep M83 The Thousand Ruby Galaxy

[markas (Mark)]

Mike, congrats on the APOD.
The galaxy's outer reaches show up amazingly - as almost never seen, and the clarity of detail in the main spiral is spectacular.


On the matter of resolution, I'm sure you are right. I recently changed from 1"/px to 0.65"/px, and it shows at my Mt Macedon site which never gets much better than 1.7" seeing...


I'm very jealous of you getting so many hours of sky time - recently I've been lucky if I can two decent nights with good seeing in one dark period

Cheers Mark, always wanted to do a good deep M83, I originally wanted more exposure but after three months of slow collection, I was impatient to see what I had and started processing and woah! I was gob smacked...so, meah, just kept going and all the aspects I was hoping for were revealed, without all the extra exposure that I had imagined would be necessary, the blessing of transparent dark skies I guess?

Since starting digital imaging back in 2003, I have done serious imaging (and visual observing), from various spots around Canberra, Maitland, Newcastle, Kurri Kurri and from Wiruna (ASNSW premier dark sky site) and Eagleview edges out or completely floors all of these places, in all aspects, seeing, darkness and transparency, its great So I am not surprised your drop from 1"/pix to 0.65"/pix is returning dividends for you from Macedon. All my gear was extensively utilized for nearly 8 years, at my old observatory at Wallaroo, on the outskirts of Canberra and then simply moved 60km south and 850m higher into the Tinderry's and the improvement has been mind boggling, in every session, both visual and imaging So yes, I am sure dropping my image scale finer will be worth it.

You can see my conditions quantified and some comparisons between Wallaroo and Eagleview HERE, it's no fishing story, I'm not making it up

Amazing comparisons Mike,
you'd hate to be trying to image from suburban Melbourne
where the seeing is often 6 arc seconds FWHM.
I've seen Jupiter and Mars from a park in Melbourne
with high end refactors.
The seeing pops in and out -
you see those planets clearly for less than a second at a time.
It would be good only for video and lucky seeing -
selecting the best frames and stacking.

I bet lucky seeing from Eagleview would be well below 1 arc second.

cheers

All I can say is well done!!!

Yes considered giving that a go, Kevin Parker does just that and has recently done some great work on some small planetary nebs, if you're on it, here is his Facebook page

Grazie Mille Antonio

Just noticed it managed to score a Top Pick on Astrobin today too, very cool only just joined Astrobin a week or so ago and it was my inaugural image posted there, so glad at least a few enjoyed seeing it

Yeah amazing capers Mike, doing these deeds are in a sense the backbone to the hobby and an inspiration for future armatures to set personal goals etc.
Valuable stuff and a beautiful image for sure

Crikey Mike that’s a spectacular images for my astro-starved eyes! Don’t think I have ever see m83 in such depth and clarity. Wonderful… just wonderful
