quickie M94

Posted By Mike Clemens

Down to a couple hours of mediocre darkness! I'm still hanging on.... Next Winter I'm going to collect so much data that I process through the Summer. Sort of the inverse of squirrels collecting nuts for the Winter I suppose. Collecting Winter photons for the Summer, I suppose that makes me the nut...

Here is M94, this is 40L 33B 16G 16B on the ST237 on the TEC200ED.

This object has ridiculous dynamic range to it. ?This would be a good one to try some HDR Photoshop techniques on?

sky brightness, signal depth

Posted By Mike Clemens

If you've got multiple series of exposures of the same object, captured on multiple nights, so the sky brightness varies between them (and their exposure length varies also) these frames can not be simply combined, the average of them would be meaningless, correct? What happens in the combine in an application like Maxim when the base background brightness varies a lot?

Large Hadron Collider Videos

Posted By Mike Clemens

Not sure what forum these would go in, these are really excellent videos.

I like the big bang history and Sagan quote in this one:

huge stinging insects

Posted By Mike Clemens

I like to sit in the (otherwise useless) observatory these last few months of sunlight and work in the nice cool temps, or surf astromart etc. I can count on the tar paper above my head all the failed attempts to build nests this Summer.

Of all these attempts only one hornet was able to get a cone going on the ceiling... his bad luck as he was forced to move to a Kenmore vaccuum cleaner, house and all within 1 day. As for failed attempts... easily 200 nests were attempted to be started this year. I geuss there is something about the tar paper they cant deal with. Maybe it's not that they ~can't~ build on it, maybe it's that the asphalt vapors or whatever is just undesirable after it gets warm the next day. (edit: no its probably not real compatible with their attachment mechanism, all the failed nests basically look the same, a single mm wide line of hornet-grout of an almost identical nature)

They make me mental.. I think it was the major stinging event in my youth involing a low bush nest, and then an impromptu creek swim.

They all bother me... it's hornet after hornet but once in a while its the nasty looking multi segmented looking wasp like things I have no idea what they are but I know they are still angry about the creek thing. I am NOT at ONE with them.
