First Shots-- Need Some Advice

Posted By Tapio Lahtinen
First, it's a great image!
Red nebulas stand out clearly.

I just adjusted curves (in Photoshop). I'm sure someone could do better than I did.
Took also snapshot of the curves and I can send it if someone wants to see what the adjusted curve looks like. Usually I adjust histogram.

However it would have been close to a record from Europe. Did anyone in Europe capture this event?

I tried but did not succeed. However on the following day I did make my personal record (46 hours 40 mins).

Have not updatet my english pages yet.

I know that at least one person here in Finland observed (and even imaged) younger moon (21 h 2 min), but have not seen images yet.

Webcam Files

Most people are using K3CCDTools or some other special software for capturing.
You can convert mpegs to avi with software (google mpg to avi).

I'm lazy so I just use Noel's Astronomy Tools actions (hard color gradient removal).
Another solution is Gradient Xterminator.

Anyway, I think it's grat shot.

Comet Boattini

I really like this image.
There seems to be faint tail pointing lower right.

Must image this when the weather finally cooperates.

My first image shooting RAWS

Posted By Tapio Lahtinen
You don't have to convert raw files to tiff because DSS can handle raw files from most of the DSRLs.

M31 Attempt - advice needed

Posted By Tapio Lahtinen
Looks normal to me.
You just need to take flat images to remove vignetting and dust bunnies.
Now it's too late for this image but you could try Gradient Xterminator for this:

Saturn

Color looks good to me but it feels a bit soft.
If it wasn't focus issue it must have been the seeing.
Some of the stars in corners are multicolor.

Just do a Google search for Dr Clay Sherrod and his service comes first.

Advice / information on CCD

Posted By Tapio Lahtinen
If you are going to do mainly planet imaging then best for these are Imaging Source DMK or Lumenera cameras.
These cameras able you to get fast frame rates which are essential for planetary imaging.
These are not so well suited for ds imaging so if you want best of both worlds you need two cameras or have to do compromises.
