VCiD,
Star pix on a DSLR? You need an A2 LED (Red) Aviator! I got mine locally <$100 on closeout 2 yr ago. Check around for old stock.

Thanks for the suggestion. :thumbsup:
Actually, I've got red, green and blue A2L's and a Kroma Milspec. But the low levels on the T1A and HDS Rotary are even dimmer to my eye and help keep night vision on a dark moonless night. The yellow-green on the Kroma seems to give me the best acuity in dim light. Whether red is best for night vision has been debated here for years and elsewhere for decades. Half a century ago many airline and military cockpits had red lighting, now I don't see it much on more modern flight decks.
Recent DSLR's can image stars and the Milky Way with an exposure of a few seconds with good results with a wide angle lens. Earlier you had to track the stars with an equatorial mount or get star trails with a long exposure.
That T1A emitter swap has really got me thinking. The heat sink looks similar to the one that holds the SSC P4 in the SF U2 and I was able to cut the XP-G board with a Dremel tool and make it work.
Then again, for low light, efficiency is not much of a concern and I've got a hundred aging CR123A's from free battery deals before SF allowed actual discounting and I switched to RCR's for most lights. :thinking:
