M1 - Crab Nebula in Taurus

Dear Friends,

Finally a small break in the bad weather we have been experiencing the
past few weeks with a brief 3.5-hr window of opportunity after the moon
had finally set to image the Crab Nebula in Taurus. I regret not
pursuing the luminance portion in h-alpha (live and learn) and I will
follow-up with a repeat visit which will most certainly include a heavy
h-alpha component.

For those interested, please see
http://www.perseus.gr/Astro-DSO-NGC-1952.htm .... the higher resolution
version available by clicking on the hyperlinked image includes a
"misplaced" asteroid on the upper left quadrant.

The seeing was quite horrible (FWHM 2.9 to 3.6 arc-secs) and a far cry
from my usual 1.7 to 2.3 arc-secs.

Clear skies!

Anthony.

I would avoid going h-halfa for a luminance but then it is up to each
individual. As for the picture the colour balance isn't the best, the
central portion is a bit too bright (hence hiding the details within) ,
it is pretty noisy and the background is too dark (except for a faint
reddish halo around the central portion of the image). Were I you I
would go for a stright 3-hours luminance followed by the canonical rgb
in binned mode.

Hi Andrea,

individual. As for the picture the colour balance isn't the best, the
central portion is a bit too bright (hence hiding the details within) ,

I had a brief window last night (3.5 hrs) and I tried to make the best
of it by splitting time between the LRGB components. This is certainly
an image to be revisited when more time is available and with the moon
not dictating how long I have at my disposal for M1.

Thanks for the input and suggestions. It is obvious that there is lots
of room for improvement.

Anthony.

Thank you, Danke, Merci !
Pas "danke" en grec, ce serait plutôt du genre "??? ????????????" mais ils
disent aussi "merci"!

Oui en fait unicode "y supporte pas l'ISO 15924" (grec).... double Pfff.

Anthony a peut-être la réponse.

Hi Anthony, king of the starfire !
I cannot post a msg written in greek alphabet...I need the iso 15924 code
How do you write in greek in your post ? (I tried to write the translation
of "thank you" in greek, I gave up!). You need a greek version of your
mailing system as well to preserve the iso codes ?

Hi Anthony, king of the starfire !

I love and cherish my AP StarFire. Yes, six years on the waiting list
but what an instrument! The only mistake I made was not placing my name
on the list for two such instruments back in 1999.

I just picked up a Tak FSQ-106/f5 for widefield work and I am now in
heaven with these two wonderful scopes.

I cannot post a msg written in greek alphabet...

I just posted some Greek text above to see if it makes it through or
not. Using the Mozilla reader in Netscape, I select View-Character
Encoding-Greek (ISO-8859-7) and the message is now enabled for Greek
characters. Next, I then select GR in my Windows (XP) toolbar so that
the keyboard can write Greek letters using the existing English keyboard
on my Dell and I am all set.

I need the iso 15924 code
How do you write in greek in your post ? (I tried to write the translation
of "thank you" in greek, I gave up!).

In Greek, we say "thank you" with "Åõ÷áñéóôþ" or "Ó'åõ÷áñéóôþ".

You need a greek version of your
mailing system as well to preserve the iso codes ?

No I do not. I use Netscape V7.2 and the Mozilla reader that comes with it.

So long now ? I expected 1.5 years, 2 at bast (worst)... sad.

To make a bino to challenge Miyauchi or Swarovski ? ;-))

No. It doesn't.

Not better (or it is my application).

You do. See microsoft. I have the same problem and I cannot fix it. I need
to check all this.
it is not intuitive, as usual to MS :-((
I expected that new fixes and SP2 fixed this as the european users (with
pressure of the european commission and his greek member) are as numerous as
the US one and have all this problem of language.
But currently it is to the user to implement this option.

How do you write in greek in your post ? (I tried to write the
translation of "thank you" in greek, I gave up!).

In Greek, we say "thank you" with "Åõ÷áñéóôþ" or "Ó'åõ÷áñéóôþ".

"Ao..." Hum! Babelfish altavista give us the right answer too but we cannot
display it in this msg, excepted your friend Philippe.

No I do not. I use Netscape V7.2 and the Mozilla reader that comes with

Good idea but seems not enough... ! :-)
Of course it shoud be supported by the OS, not only by the application.
I haven't find an installation procedure online yet.
I could ask to some friends at E.C. is needed.

Although my usual newsreader, MT-Newswatcher v3.5.1, was able to
identify the encoding correctly, the Greek text was garbled in the
display. However, it looks just fine in Mozilla Thunderbird v1.5.0.7, so
I presume the fault is MT-NW's and neither my system's (Mac OS 10.4.8)
nor at your end.
