New Images from this weekend.

Posted By James Brown

Very dramatic Floyd. Did you flip the image left to right? In my refractor images of the same region, the horse looks to the left.

Why are my colors so weak!!!

Hello guys

has anyone an idea of why my color channels are so weak?

These are the average combine of 12 10min subs taken with my TEC180 at F7 with the SBIG STL11000XM unbinned. I know I should have probably binned the exposures, but I wanted to keep the star size as small as possible to match what I considered a good h-alpha luminance.
However, I thought that 2 hours of color would have given me a pretty good result, but I was evidently very wrong :C

Any help/suggestion would be greatly appreciated: I'm loosing sleep over it, while I should loose it imaging sad

Ciao
Luca

Hi Luca:

The linked article by master astrophotographer Robert Gendler helped me a lot. Often the luminance data initially overwhelms the color channels. This article is very helpful in dealing with this phenomenon, note though that the technique described is very Photoshop specific.

Good Luck, Jim

Sombrero - M104

Nice capture Jim. I love M104 images. The nearly edge on galaxy disk and halo structure are so 3D looking with the prominent dust lanes. Very nice!

M63 & M51 - First Light Images

Posted By James Brown

Tyler Allred said:

Hi all.
These images of M51 and M63 are first light with my new Starlight Xpress SXVF-H16 camera. I quite like the field of view and the square shape of the sensor. It makes for a little different composition. The links are below. Be sure to click on the images for the full versions. Comments and suggestions are always welcome.
Cheers,
Tyler

Hi Tyler;

You've been busy! all of these look great. Is this the camera that is getting a new filter wheel?

Request to remain on-topic !!!!

Posted By James Brown

Anthony Ayiomamitis said:

Folks,

Can we please try and remain on-topic within this group? During the past few weeks we have had a few threads surrounding equipment and which is most appropriate in other equipment-related groups including TeleVue and refractors.

I remind everyone that the description for this group reads "DEEP SKY IMAGERS have their own unique Imaging and Processing issues - Now they have their own FORUM" and it is both frustrating and tiresome seeing LENGTHY threads which not only do not belong here but have other groups here on Astromart where they are ideally suited.

No, I am not the administrator but an interested reader and participant!

Anthony.

Hi Anthony:

No disrespect intended, but the recent equipment threads seem to be right on topic to me. The discussion of various astrograph varieties was/is very informative and specifically targeted at the suitability of these various telescopes for deep space imaging.
