Here is a photo of the same object that I took recently.

It isn't great, but it is only 36m exposure. I'll try to get
more on it if the sky ever clears.

Very impressive. I never get a sky like that near Boston. However,
here's a picture of the same object I took from a higher perspective.

OK, I was not the lead scientist, but almost all of the data processing
software, from decoding the telemetry to putting the picture on the
display was written by me, and I was at the keyboard when the NASA
photographer took this picture of the screen. In '78 color displays were
so uncommon that we didn't pass around picture files, we photographed the
screen, usually with Polaroids, but 35mm for publication. Each little red
dot is actually one x-ray photon, focused by a "grazing incidence mirror
system." Magic! This picture was one of the first we got of a nearby
galaxy showing individual x-ray sources, so it caused quite a stir.

I just don't get it. Why would anybody waste their time and money futzing
around with tiny little amateur lenses taking tiny little amateur deep space
photographs when there are millions of REAL large and detailed photos
available from Hubble alone? You could look at them your entire life and
not see them all.

Seems to me this amateur snapshot-taking becomes more and more of a waste of
time as time passes and anything but the very large and very large array
telescopes taking photographs is a joke.

But, even worse is when people start bragging about how great their inferior
little lenses are. There's nothing great about them. They're tiny and
they're a joke. The photos taken by them are tiny, inferior and a joke as
well.



Actually, you have a point, which is why I don't waste too much effort
on that type of shooting. I prefer artistic portraits such as this,

And I do mess around with macro, as in this shot where you can see me
reflected in the larger eyes....

But if you love shooting the stars then by all means go at it!
