Mars Magnification?

Posted By Dave Mitsky
Mike,

Mars does indeed look good at magnifications of 400x and above.

North American Nebula

Posted By Dave Mitsky
The North America Nebula is usually visible with binoculars from dark sites. At the best ones that I frequent it is also visible through a rich-field scope such as a 101mm Tele Vue or 80mm Orion ShortTube without filtration. A narrowband or O-III filter will greatly enhance the view.

IC 1296 in Lyra

Posted By Dave Mitsky
I have been unable to see this galaxy through a 20" classical Cassegrain and a 25" Newtonian although sharper-eyed observing companions have.

What could I see with a 33" ?

Posted By Dave Mitsky
I've looked through the 36" Tectron Yard Scope a number of times as well as a 36" Obsession at a recent Stellafane convention. The Antennae were unbelievable through the Yard Scope.

At the 1996 WSP I had an opportunity to observe through a 33" ATM Dob. My view of magnificent barred spiral galaxy NGC 1365 was almost of photographic quality.

I've also spent a fair amount of time at the eyepiece of John Vogt's excellent 32" ATM Dob and another 32" using John's first 32" mirror. The central star of M57 was easily held directly on one occasion. M27 was ridiculously bright. Stars in globular clusters such as M15 took on a distinctly yellowish hue.

This past Friday I had the opportunity to use a 30" ATM Dob at the Laurel Highlands Star Cruise. The bridge between M51 and NGC 5195 was easily visible as were M20's dark lanes.

Mars Observation (June 26, 2003)

Posted By Dave Mitsky
Carlos,

My views of Mars that morning from the Laurel Highlands Star Cruise were similar but without quite as much detail using a 14.5" Starmaster Dob, apodizing screen, Wratten #21 filter, and magnifications up to 520x.

TeleVue Nagler Zoom 3-6mm/Pro or Con?

Posted By Dave Mitsky
I have mixed feelings about my 3-6mm Nagler. Most of the reports that I've seen state that the best orthoscopics provide better images (I haven't had a chance to do any direct comparisons myself) but the convenience of the zoom is hard to beat. I find the eye relief to be adequate.

Astronomy...safe?

Not as much as walking headfirst into a 50 pound counterweight I'll wager.

Barnard's galaxy bagged...

Posted By Dave Mitsky
Jim,

As it turns out two of the many objects that I observed from a dark site in Pennsylvania's Tuscarora State Forest on 7/30 UT were NGC 6822 and NGC 6818. The conditions were excellent. I used my Tele Vue Geneis sdf refractor for those particular objects and many others as well. Also employed on that very busy night was Tony Donnangelo's 14.5" Starmaster.

Prior to this my smallest aperture observation of NGC 6822 was with a 114mm Newtonian.

Calling Mars experts.

Posted By Dave Mitsky
That's quite a nice recent image, Angel.

Have you been using the 18mm Ultima much lately?

Why is Hellas shown as white?

Posted By Dave Mitsky
Perhaps because the Hellas basin is frequently the site of frosts and clouds?
