~9 hours on M 33 with an unguided AG12

[Grinde]

Ahoy mateys!

I finally had the time to process some of the data I've acquired during this autumn, my current workload have "forced" me keep shooting completely automated data from my roll-off-roof observatory 12km outside my city.

This have been by far one of the toughest targets to process, even though I had quite a pile of data to juggle with, there's endless of stuff embedded in the spiral-arms that took great concentration and discipline to bring out without throwing off the rest of the image. Data aquired during 5 different nights, shooting the subs when the target was in the highest position of the sky.

I've also included an annotated version where tons of dss2-galaxies are marked and labeled with magnitude. Moonlight during the lum-acquisition limited the background-depth somewhat.

Aquisition:

ACP + Scheduler

MaximDL

FocusMax

Telescope: Orion Optics AG12

Camera: QSI 583 wsg-8

Mount: 10Micron GM 2000 HPS

Guiding: Unguided

Exposures:

Lum : 77 x 180s

Red : 20 x 180s

Green : 20 x 180s

Blue : 20 x 180s

Ha : 12 x 600s

Total time: 531 minutes / 8.9 hours

I've just implemented a smooth transition "mouse-over" function for annotated images on my homepage, it's very interesting to spot the weak background-galaxies without having to alt-tab between the two versions...

Stunning level of detail and considerable work/dedication in the processing.   The annotated version looks very professionally done, extremely useful though I prefer the naked image - is this information derived from astrometry.net as a plate solve on the final image?

Very pretty Jonas

[nmoushon]

Thats amazing! Well done!

[red dwalf]

i don`t think i`ve ever seen so much colour in M33 before, and a stunning level of detail, truely amazing

  HOLY MOLY!!!!!

[perfrej]

Yep! Way to go!

Trying to type a response, but it's not easy with my jaw on the keybbbarrrrd.

Impressive stuff Jonas.  You've really got the AG12 working beautifully.

Thanks a lot for the kind and encouraging comments ppl!

Both platesolving and annotation-info was made using PixInsight : ImageSolver and AnnotateImage scripts

This is so good it's difficult to know what to say! Simply awesome.

Heh heh. That's good! That's very good indeed! Delicious detail and the familiar processing skill which hauls out the detail without any sign of 'processing' whatever. Stunning, Jonas. You are a world class player.

Unguided? Well, your mount does guide on itself! I wish mine did!!!

Lovely.

Jonas,

That is a remarkable image, your processing is perfect. Did you use PixInsight on this? I have seen

many overprocessed images done with PI that end up looking like paintings instead a pictures.

But none of that here! Great scope too!

Why only 3 min subs in lum?

Best regards,

Pieter

top stuff, does not look processed at all, I wish all galaxies were like this.

Sweet!..... :icon_salut: :icon_salut:

Respect for a fantastic result

[andyo]

Fantastic image,great colour.the detail is superb from the outer regions right into the centre

[psemil]

Very beautiful image. I like very much the way you process your images.

[Thommy]

Fantastic Jonas! I like the HII areas in particular. Quite often th HII regions in M33 seem very bright but with no detail at all ( I think someone else used the word "painting") - not here! Plenty of details within both HII regions and star fields

Great shot well done

[Russe]

Superb image!! My meagre first attempt can't compare to this amazing detail!!!

[Tom OD]

Excellent Jonas,

Beautifully processed, you made it look effortless. Super pic. Lots of detail, and silky smooth. Lovely star colour, and I did notice on the larger version, they are a little diamond shaped. Is that from the spider in the scope, or was that from star work in the processing?

Tom.

Truly stunning!
