Dark sky observing site choices - What would you do?

Posted By Judson Mitchell
Based on your description and apparent residence, it appears you are talking about the Alpena area as your observing location. If so, my guess is that the difference in light pollution and therefore observing quality is marginal between the two locations, assuming they are only a few miles apart. Have you compared the two sites? Regardless, having a dedicated observing site that you own is a plus. Just watch out for the porcupines.

Where can I get bulk foam, pluckable or not.

Posted By Judson Mitchell
Same as John says. Easy to cut and holds its shape well. Talking about the 2.2# 2" black polyethylene foam.

12MM Nagler T4

Posted By Judson Mitchell
Not sure, but the one I borrowed a 12 T4 from a friend did have a moveable eye guard. In fact it startled me when first used making me think I broke something. What about a T2?

Okie Tex 2009

We also were there Saturday through Tuesday and just skipped out on Wednesday due to the prognostication. To add insult to injury, we drove 2900 miles total to get there and return and did not pass anywhere that we thought the sky decent enough to stop and observe, even with binos. What a way to christen your first star party and trip to a truly dark site.

Not sure where we have the right to that information unless there is something criminal involved.

Climategate a right-wing conspiracy?

Will we ever find the truth and recognize it when confronted?

Political Science

Posted By Judson Mitchell
One thing that has always bothered me was the depiction of global temperature change on a rectangular map with the north pole which is a dot having the same linear dimension as the equator. Thus reported temperature change appears skewed with respect to supposed area. This is not an accident. There are more accurate ways to show this data. Things like this are what make me believe there is intent to distort the perception of the information. Just me I suppose

Inconvenient

Posted By Judson Mitchell
What I have seen is an increase from the media in pointing out areas where environmental problems are occuring. The only explanation being offered is global warming, but in some areas other environmental issues exist such as over grazing, denudation, etc. It is parallel to some medical presentations which try to lead us to a preferred cause and effect relationship, when there may be circumstances that another selection process is acting. An example would be a group having an inherent resistance to a certain malady also having a preference for that which is suggested as the cure. Very seldom is that type of relationship considered. My point is that we must be very careful in establishing cause and effect relationships.

We may get a break tonight along the NC-SC border in the extreme west. We can only hope. Probably up towards the Parkway.

New to me OTA - Questions

Posted By Judson Mitchell
My 12" GSO dob gave very asymetrical star tests for in focus and out focus before Ed Stevens refigured it. Even though two separate tests indicated that the mirror was around 1/7 wave. Star tests are now very similar plus individual observers have noticed the significant difference of before and after for my mirror. Two independent tests showed that the mirror was slightly undercorrected and that my scope showed increased detail on Jupiter using an apodizing screen. That was interpreted to indicate that the apodizing screen was acting as a mask selectively reducing light from the edge of the mirror. After refiguring, the apodizing screen did not increase detail on Jupiter. To make a long story short, regardless of the stats that were provided with my refigured mirror, the proof was in the pudding and I am very satisfied with the results. I thank Ed Stevens for that.
