first project, 10" vs 12"

Posted By Jake Jacobson
Hi Mary -

I don't think there is so much a difference in weight if you are making a truss dob. If you were making a tube dob, there would be a more significant difference.

The kits might be a good idea if you have no carpentry skills.

Vehicle Recommendations

Posted By Jake Jacobson
1976 Toyota Chinook

Holds all my gear and sleeps 2 comfortably. It is built on a small truck platform, and can get to many hard to reach places, and is much lighter weight than a cabover (also with a lower center of gravity.) Heater keeps me warm at 0 degrees. 17mpg. It is quite old, but still very reliable.

Hi Eric -

That is a very nice photo.

As a suggestion, you might wish to post your photos over in the "CCD imaging" forum instead of here on the "equipment talk" forum.

What order to do processing steps?

Posted By Jake Jacobson
Hi John -

I am by no means an expert, but FWIW I have had much better luck performing all the processing (curves, etc.) after the stack. If you process each image before the stack, all you do is help to bring out the noise in each image.

Also, I believe the gradient should be subtracted out of each individual image prior to the stack.

You might want to ask the question again on the imaging forum where the experts are.

Triesnecker and Hyginus area

Hi Johannes -

Looks quite good. Your focus is exceptional, and the detail is marvelous. It does seem, however, that the brighter areas to the right are slightly burnt - is this from overexposure or processing?

Nice work,

Jake
