hi,

Otherwise know as the Packman Nebula. You did a great job getting and processing the
images.

"This is another object that I think has some interesting structure and nebulosity."

I agree wholeheartedly.

Hi,

Have not seen Jeff's image. I must say yours is very nice.

"The expression of the beautiful is in direct ratio to the power of perception acquired by the artist."

love the quote .... If I had said it I would have added the words "appreciation and" before the word expression. It is very true. Sadly, most of us do not spend enough time enhancing our powers of perception.

hi Johannes

That is a beautiful image, wonderful details and colors both in the nebula and stars.

One of the very very best images of Thor's Helmet I have ever seen !!!

hi Floyd

" Did I do the right thing by purchasing the best that I could find or did I waste my money in my rush to excellence?
This was the intent of my latest set of threads, to determine the truth and wisdom of buying the best of the best."

I would think only you can determine the answer to your question. I'm sure you belong to an astro club and attend star parties. Set up your scope next to others of the same aperture and without "premium" optics and look. Is there a difference and if so how much of a difference and if so was it worth the price ?

I learned a lot reading this thread. My take aways ... there are a lot of ways to measure a mirror, there a bad, good and great mirrors. At some point of excellence most of us, most of the time, can't tell the difference between a really good mirror and a great mirror.

hi,

Lots of factors are involved in picking a site and they differ for a single night viewing session ( with a return home ) and a weekend or more camping session.

Distance

I would say one hour or less for a single night session and up to 3 hours for a weekend session ( 3hrs enables you to observe both nights, any longer requires a 3 day weekend IMHO) .

For a single night with return home multiple sites may be in order on different sides of the light dome you live in or near.


Darkness

For a single night I'd settle for mag 5.5 skies at the zenith. For a weekend I'd want mag 6.5 skies.


Altitude

Darkness is a more important consideration. However if anything over 2500 feet is available then thats a plus. High altitudes ( 9000 feet ) can be somewhat of detriment visually as the low oxygen levels will decrease visual acuity and sensitivity.

Horizon


As I tend to look up more then sideways to get better seeing and less extinction ....30 degrees and up is fine.


Accommodations

A State park or National Park is better then the wilds for a camping trip.

Seeing

Try to avoid downwind from mountain ranges.
