Hi Paul,
many Thanks for your congratulations.
I am wondering too, why faint stars seem so red
in most cases. Is it because the film is faster, more sensitive in the red
layer? Or is it the same effect as the red sunset, because M8 is quite near to
the horizon? I prefer the first thesis. Faint stars at all have either no color
or the tend to red, especially on negative film.
About flexure, I found a place during the last
session. My excenter was not tightened well, so I got star trails on the film.
But this was my fault, not from the equipment. Both focusers of the guiding
scope an of the VC200L are well designed with plastic strips in the opposite of
the focuser shaft and both can by fixed in position by a srew.
Translating my text into English is necessary,
because there are so many more astrophotographers outside the German speaking
area than inside. And the idea of a web site is the possibility to discuss with
others, not only presenting the images. But it is funny, because I
Know some foreign language web sites, where I can understand the technical
informations, without knowing this language.
bye,
Manfred

Hi all,
I´ve just uploaded a new image of M8. This is my
first image with the VC200L at f/6.3, using my focal reducer and my new
custommade mounting rings.
The image of M8:

Dear
Manfred,
Your image of M8 is lovely! I am wondering why so many of the
fainter stars also appear red. Is this because some of the H II emission from
faint tendrils extending out from the body of M8 is giving them a false
color?
I also admired your clamping rings on the Vixen which were
machined to contain integral rings for your separate guide scope. They appear
extremely sturdy. I did notice a place where I get flexure in a similar scope:
at the focus adjustment and telescoping tube. How are these reinforced to
prevent flexure from occuring here?
Finally, I appreciate your
translating the German text into English. However, not all of the German text
was translated into English. I was able to use my ancient German to read most
of what you didn't translate and appreciate the additional information you
placed there. Thanks for being so
complete!
Aufwiederhoeren,
Paul
