Thanks for some new ideas to me.<quoted text>
We tried the H@ filter, once in a while on galaxies. We found it marginally functional on hot new stars in dark molecular clouds in some very near galaxies. But most often it raised contrast by eliminating lots of wavelengths. Generally, with our smaller scopes & desire to see far distant 12 to 15+ magnitude galaxies, that precluded the use of the H@ filter.
The H@ filter is spectacular on a star 8 light-minutes away......... not so good on stars 300 to 500 million light-years distant, even 100,000 stars burning in the ultra-violet.
Never got the opportunity to use the H@ filter on a 40inch Dobsonian telescope on some of those near-by galaxies.
There are 27 comments on the Sacramento Bee Newspaper story from Dec 30, 2012, titled Editorial Notebook: 'Chasing Ice' captures beauty and tragedy of melting glaciers. In it, Sacramento Bee Newspaper reports that:
Seeing "Chasing Ice," a new movie that chronicles the rapid disappearance of the world's glaciers as man-made climate change proceeds, I was reminded of Francis Ford Coppola's "Apocalypse Now." In "Chasing Ice," we watch transfixed at the beauty of ancient ice mountains larger than Manhattan falling into the sea even as we are struck by the horror ... (more)

We tried the spacedoutblues filter, once in a while on galaxies. We found it "marginally" functional on hot new stars in dark molecular clouds we visit in some very near galaxies. But most often it raised contrast by eliminating lots of you and I wavelengths. Generally, with your smaller scopes we desire to see the large makes us unconfortable in the far distant 12 to 15+ magnitude galaxies, that precluded the use of the spaceoutblues filter.
The spaceoutblues filter is spectacular on a star 8 light-minutes away hard to wait that long, not so good on stars 300 to 500 million light-years distant, even 100,000 stars burning in the ultra-violet.

WOW another precious momment.

Yeah, I'd like to see Promised Land. Van Sant's new movie, with Matt Damon.
Wish that greenies would stop attacking gas, however. Unless we get solid evidence that methane leaks are a major climate problem, gas is a very, very useful stopgap to replace coal while we wait for solar to become cost efficient and widespread.

New research seems to conclude that some of the latter decade rises in atmospheric methane WERE due to methane leaks. However, quite a bit of work by the gas industry lately, have slowed methane leaks. Atmospheric Methane increases have slowed in recent years, despite the increasing emissions from permafrost & Arctic Ice Shelf clathrate warming.

'Atmospheric Methane increases' should be:
'Global atmospheric Methane increases'

WOW, more "phud feces face" misspellings. When he keeps to copying my posts tho, his spelling improves.

Say what!!You lost control when the tina spanked you again.You couldn't save face if fairy lame and spacedoutblues gave you a helping hand.
