NGC7380

Hi there,

I had clear skies last night and a full moon so I needed an Ha target,NGC 7380 was my pick.I have seen so many great images of this,including Philip Goods Pic of the day.

Heres my attempt at it smile

Image is 18x600s through an Astrodon 6nm Ha filter.
ST10xme
Vixen VC200L at F6.4
1200gto,boy do I love this mount smile

I think I should have went deeper on this,some of the faint outer nebulosity was very weak in signal,best I could do was blur it up a bit to make it look better.

Thanks for looking,

Jason

M1HaRGB

Posted By Jason Boyce

Hi all,
I collected some color subs to go with the Ha I shot back in November.I actually shot these on Dec.3rd and have just got around to processing.

Seeing was especially poor so I binned 2x2 for the color.

This is my second attempt at HaRGB,it is much more difficult than I thought to try to get good color!I may have oversaturated this trying to compensate.

I also got just to the upper left of center what I think is an asteroid,not sure yet though as I have not tried much to find out.It was pretty cool to blink the images and watch it's movement.If you happen to know what was in the area on Dec.3rd I would love to know.

Here is the best I have come up with and some details.

About 4 hours of 6Nm ha in 10 minute subs.
10x180s each RGB binned 2x2
CCDStack for calibration,alignment and RGB combine.Photoshop for the HaRGB combine,levels,curves.

IC410

Posted By Jason Boyce

Hello,

Had a bit of clear sky last night,conditions not very good with poor seeing and transperancy but thought I would make what I could out of it.This time of year it could cloud up at anytime and stay that way for a long time!

I decided to shoot Ha and chose IC410,again.I threw out 18 ten minute subs on this a few weeks ago due to poor focus sad

I shot 13x600s with an Astrodon 6nm Ha filter before conditions became too poor to shoot.

Calibration,alignment,data rejection and combine in CCDStack.
Deconvolved in CCDStack 25 iterations.

Levels,curves,sharpening and noise removal in CS2.
I tried not to get carried away with the noise removal,hope it does not look too overprocessed.

The cluster below the Tadpoles in this image is NGC 1893.

Is it just me or do they look like they are smiling wink

Thanks for taking a look,comments and suggestions always welcome.

IC410HaRGB

Posted By Jason Boyce

Hi,

I shot a bit of LRGB Sunday evening for the Ha I already had on this.
Typical crummy conditions I have had for the last month,I had lots of problems with the stars,FWHM on the LRGB from 5-7 arc seconds 8O

This is now about 2 hours of Ha,1 hour Lum and 48 minutes each of RGB.
I combined it as (HaRed)(HaLum)LRGB

I'm was happy to see it turn Red instead of pink!

IC417 in Ha

Posted By Jason Boyce

Hi all,

I shot some more Ha last night,this time IC417 in Auriga.

There is a lot of faint nebulosity in this part of the sky and I picked it up fairly well with the 10 minute subs I took but wish now I would have gone 15-20 on this one.

Seeing and transparency both fair to poor.

Maybe some color on this one when it stops snowing wink

This is 18x600s with a 6nm Astrodon filter

Darks,flats,alignment,combine,DDP and slight deconvolution in CCDStack

Levels,curves more sharpening and slight noise reduction in CS2.

Resized to 50%

Thanks for looking,comments always welcome.

IC417 HaLRGB

Posted By Jason Boyce

Hello,

I shot some color last night for the previous 3 hours of Ha I already had on this.

This image is now 3 hour's of 6 Nm Ha,1 hour Luminance and 30 minutes each of RGB combined as HaRed,HaLum,LRGB

I really did not get enough color and had horrible gradients from the not very transparent skies last night.The two bright stars posed me lot's of problems too(large Green halos 8O )

I dealt with these the best I could,can't seem to get rid of them completely.All in all it's a bit of a dissapointment because I had higher hopes for this one,probably reshoot it sometime smile

M37 up close and personal

Posted By Jason Boyce

Hi,

I shot M37 a couple nights back through holes in the clouds.
This was something of a FOV test with My St10 at prime focus of the Vixen VC200L smile

It fit but close!

NGC2158

Posted By Jason Boyce

Hi all,

I shot this a couple nights ago,I was looking for something that did not need long exposures because of low transparency this night and thought this would be a good choice.

I think it came out ok but I did have gradients do deal with even with relatively short exposures.A bit noisier than I had hoped for.

30 minutes Luminance,40 minutes each RGB

Discovered by William Herschel in 1784 and estimated to be about a billion years in age 8O

M82

Posted By Jason Boyce

Hi,

Monday I had some of the better conditions I have seen in awhile,transparent skies and ok seeing.I decided to give this one a try.

I get pretty harsh gradients in my subs that are longer than a couple minutes from the neighborhood lighting so I made an extended light shield for my scope adding about 16" to it's length,nicely flocked the inside in hopes it would help keep some of the porchlights at bay.
Unfortunately I see no differance in the amount of gradient :C
Back to the drawing board.

Anyway here is the image of m82.
Taken with my VC200L and ST10xme at F9
34x180s Luminance
12x300s RGB

I was hoping to get a bit more of the out gassing but I guess that would require some longer subs and some Ha added in.

Thanks for taking a look,comments always welcome.

Posted By Jason Boyce

Hi all,

I got somewhat clear skies the other night,pretty hazy so I went after this cluster to keep exposures short.

I think it came out ok but I'm not sure on the color balance in the background so opinions on how that looks are much appreciated.

It is a LRGB consisting of;
L-26 minutes
R-23 minutes
G-23 minutes
B-30 minutes

Taken with my ST10xme on a TMB115 at F7

Thanks for looking,

Jason
