Fed Up At The PumpPosted By Floyd Blue |
Unfortunately the gas prices in California will never be equitable. The gas taxes are not linked to roads and things like that, it is a way to boost revenue. As long as we have politicians in Sacramento that are wanting to spend money on just about everything, like the stupid High Speed Rail project, we will be paying through the nose.
The problem is, you can't have a liberal state and not have the people strapped for the cost of every bleeding heart liberal agenda. We spend so much money on things that we could cut back on, but that is not about to happen as long as the Democrats run the state.

DIY Thermoelectric (Peltier) Cooling ModulesPosted By Floyd Blue |
The biggest issue with cooling is to keep the chip for getting condensation, so you have to have a sealed chamber flushed with an inert gas preferably. But using desiccants you can keep the interior of a camera relatively dry, SBig has sealed chambers and a desiccant plug.
Then the next problem is keeping the CCD window free of ice and dew, this requires either a sufficient space between it and the ccd chip or a dew heater to keep it clear.
Also, it is not just cooling that makes it nice, it is controlled cooling, so that the chip stays an exact temperature throughout the session. This allows you to use a master dark frame that is taken at this temperature. As it cools the hot pixels shrink or lessen in brightness. So it will change all night if it is not controlled.
So yes, cooling will help. But getting that cool -28c will invite icing or dew if the camera in not properly designed.

"Let's cut the UFO crap" can of wormsPosted By Floyd Blue |
OK, now that I understand the post a little better I can comment. 
I am not sure that anything is impossible but there are things that are highly unlikely. In my youth I thought that the ability for a ship to travel to earth was more likely than I now realize.
Of course if someone out there has figured out how to travel faster than light, then the likelihood increases. But so far it seems unlikely that this type travel is possible outside sci-fi.
The biggest problem for me on ancient astronauts is the improbability that they would pick this star in this remote area of the galaxy to visit. Again, if they have advanced techniques to find planets as we are developing this this would increase there ability to find us and maybe even decide to come visit.
But then again, even at light speed the distance between our world and theirs is not to be taken lightly. It would require either generations of astronauts that never return home, the ability to enter into stasis to allow long trips without aging or the species would have to live a VERY long time indeed.

nagler 7mm type 6Posted By Floyd Blue |
If your description is a smooth barren without the large folding eye guard, then this is not a current model of type 6. The only type 6 7mm Nagler is found at this link.
