Default ASTRO: Eagle nebula detail Pilars of creation

HI all,
Here a quick shot of the centre of the eagle nebula.
10 x 90 sec
H-Alpha filter
10" SCT.
Homebuild CCD cam cooled to -14degr.
the sky wasn't that clear (lot of moisture which makes the stars bigger).
Will try again with more transparent sky.
Processing was done in Maxim and CS3
thanks for looking,

very nice dirk! my mount has problems with tracking accurately for more than 1 minute, even at
f/6.7. What mount do you use?

Martijn thanks, i use the classic LX200 mount which i modified in many ways.
it's capable of tracking for more than 180 sec without using a autoguider.
I also trained the PEC last spring which also helps a lot.
But it still needs a lot of fine tuning.

nice

I recommend taking longer subexposures if your mount can handle it Dirk

The KAF3200ME you are using (correct?) can handle a lot more signal than you
are getting in 90 seconds through an Halpha filter

you will get much nicer detail in the background if you do that.

For a 10" SCT even at f/6.3 you need at a minimum 3-5 hours of exposure time
if you really want to get the detail and have a smooth image.

here is one i took a few nights ago: it is 7 x 20 minutes at f/7.2 roughly

Thanks Richard, in fact the chip i use is a Sony ICX083 same as used in the
starlight xpress serie 916.
The mount can handle longer exposures time but this evening i had a lot of
trouble with the transparacy of the sky.
So i hope to collect more info coming days, but that's also a big question
mark because it looks like the autumn has come early this year with lots of
clouds and rain.....

I like your version of the eagle. did you also get a closeup of the pilars?

hi dirk, you're in the netherlands I believe (as am I). indeed.... with the weekend
approaching, so did the clouds....
last weekend we had a few excellent nights, at least here in Elst (utrecht), which gave me the
opportunity to try out my new gear.
