["Tom Mozdzen" <tjmozdzen@xxxxxxxxx>]

Hi everyone,
Last night, transparency was very good. I'd rank it definitely above a "7".

Seeing has been pretty horrible both last night and a week ago Friday. Warm
gusts of air in the freezing night can only mean trouble.

We had two visitors last night around midnight - 1. a car passing by very
slowly. 2. 20 mins later, a search helicopter with the full spot light
turned on. At that point, I decided it was time to take a last look at
Jupiter and Saturn and then pack up for home.

On a side note, Mike Mello and I took a few looks at NGC 7635 with both our
scopes, no filter, UHC, and OIII filters with the 31mm Nagler. My notes from
the all AZ star party listed this object as not very impressive - a bright
nebula.

After trying both of our scopes, it turns out that this object looks very
nice with an OIII filter with low magnificaiton. I don't know the specs on
Mike's scope, but he gets a bigger field of view than I do with the 14.5"
f5.1 dob. The UHC filters and no filters with a 31mm Nagler on both scopes
produced a so-so object. Only the OIII in Mike's scope produced a truly
detailed "mottled" looking nebula worthy of being on the EVAC list.

As a suggestion to enhance the various lists we have, I would like to see a
column describing what type of instrument, mag and filter shows the object
best, especially if there is only one setting that truly brings the object
out.

Tom
