Silver coin -first full picture

Hi Everyone,
This is my first attempt at a fully stacked picture with my
new 10" f4 carbon fiber Newt. with ONTC mirror.
It's over 3 times faster than my old 8" f6 Newt.
It's taken me 10 months from the time I decided to buy it
to get it fully operational.

It consists of 57 x 2 minute frames all binned 1x1.
There are 22 sub frames of Luminance - the rest in RGB -
flats, darks & bias frames applied -
from an outer suburb of Melbourne.
with a QHY9 mono camera, Astronomik 2" CLS-CCD filter in front of all 2" filters.
PHD2 guiding using dither with Lodestar & TS9 OAG,
Baader RCC1 coma corrector.
Processed with:
DSS, NASA FITS Liberator, PS CS5 & Fitswork4.


The full frame & a 2.2 MByte version is available on flickr here:

Rotated & cropped 1 to 1 pixels:
A bit noisy - needs more integration time:

edited to show a more blue flickr version.

There are many background galaxys just visible in the full frame.
I am pleased to be able to present something after such a long time.
I look forward to taking many more pictures & with a lot more integration time.

Any comments welcome.

cheers
Allan
