Another leo trio composite

[MikeD]

Hi all.

While shooting the colour for my NGC3628 image withmy 10" newt, I was also shooting the Leo trio in wide field with my 80ED and the QHY8 I have on loan.

I have now used this wide field shot (re sampled X2) as a backdrop for the NGC3628 shot this week along with the M66 I shot in March and M65 from 2009 (all shot with the 10" newt and re sized to 86% to match the star field).

After I have captured the Ha I need for ngc3628 I hope to re do M65 with updated data (I lost the raw data from 2009 to a hard drive failure), all the while adding to the wide field with the QHY8 to bring the noise down.

Thanks for looking.

The croped image at 100% is Here

The full frame at 30%

A crop at 50%

and a 100% crop.

Just noticed some red gradients to the background now it's uploaded.

I'll have watch for that when I process it again with new data.

Fantastic

Great! Very nice looking, and I can't see any red gradients really, sure the background isn't all neutral but that sometimes 'kills' it a bit if it's too uniform grey?

A few funny columns still tho, did you try any tricks on those?

Sharp image and nice colours all over as far as I can tell!

Very impressive

Yes I cloned them out but only after croping around the area of interest.

Here is the full size crop (with red gradient fixed), I will concentrate more on the full frame image background when I get some more wide data.

Wow, glad I clicked on that link! I really like it!

Hi Ant.

Hope to get your QHY8 attached to the newt as soon as this one is finnished.

[Shibby]

Seriously incredible, fine detail Mike!

[Quatermass]

Wonderful stuff love all that detail as well

[MikeD]

Thanks guys.

Brilliant detail in this.

Excellent pic, and the hamburge glaxy looks very big for an 80mm scope. Smooth background which I like. Can't see any red gradient in the first pic.

A superb set of images Mike. In particularly the hamburger. that just looks delicious!

Sorry I should have been clearer.

The 80ed data was used for the star field which has been re sized x2 and then The galaxies shot with my 10" newt have Been added (at 86%) as layers.

I have edited my first post with a clearer description of how the image was achieved.

The latest batch of RGB widfield data was captured while shooting 30 minuite subs in Ha for NGC3628 this surprisingly was not enough to bring out the Ha I know is there.

The image is now....

wide field ( April 2012)

63 @ 300 seconds with QHY8 and 80ED.

NGC3628 (April 2012)

L = 39 @ 600 seconds

R = 6 @ 900 seconds

G = 15 @ 300 seconds

B = 8 @ 360 seconds (should have been 15 but clouds stopped play)

M66 (February 2012)

L = 58 @ 300 seconds

R = 20 @ 300 seconds

G = 10 @ 300 seconds

B = 10 @ 300 seconds

Ha = 9 @ 900 seconds

M65 (April 2009)

L =28 @ 5 min's

Ha = 10 @ 5 min's binned x 2 and 10 ' 2.5 min's binned x 2

R = 9 @ 2.5 min's binned x 2

G & B= 15 @ 2.5 min's binned x 2

I have taken a bit more time on the QHY8 data this time trying to preserve star colour (which is a first for me)

that's a total of I think over 29 hours at the scope so far.

below is the new process with more wide field data.

1st is a crop at 30%

2nd a crop at 50%

and the full size full frame(almost) image is here

Great images

[Gina]

Lovely, nice details and colour

[Spikey]

Awesome work Mike, really interesting to see some of the processing workflow involved. How many hours do you think you've committed to the processing so far?

[MikeD]

Not too sure but it must be over four hours given there is at least four images in here.

Mike.

[psemil]

Very Nice.

[ultranova]

wow so sharp, and the colours are fantastic

[MikeD]

Thank you.

Mike.

[Rattler]

Great images with plenty of detail.
