Hi all,
been some weird weather here of late....(What's new with all of us!)
After a pretty long dry hot spell, we had lots of monsoonal feed down from
the north western part of OZ and finally got some rain.. needed it!
In between clouds on Tuesday night, I went out, seeing was quite iffy,
but took a chance that the transparency would be ok... it was!
Great what a sprinkle of rain can do to help settle things!
Unfortunately I didn't get my collimation spot on with the Catseye..
too much of a hurry, time was running against me but pressed on... get to bed
early... work commitments, beat the clouds, you know the story.
With the weather being so changeable here this time of year, it throws my collimation all
over the place and I need to sort it every time out.
Was a little pissed off with my impatience I can tell you.
But was very impressed with the amount of detail I picked up even with
the scope being out of collimation, unbelievable that FWHM got down as low as 1.25 at times.
The ghosting
and mushiness to the stars are a give away... with an undersized secondary and a fast
system, things are very critical as you can imagine.
Will get some more lum on this to fix the stars and some colour when, if this
weather wants to clear. But moon is coming again... but thankfully DLST will
be finished on the weekend. Jeez, have to be the worst thing ever invented for astro photographers hey
Details:
scope: 10" F4 home made Newtonian.
Main CCD: HX916 usb 1.1
Exposures: 20@ 3min subs guided(HX516 usb 1.1/ ED80)
Thanks for taking a peek John, Ric, Jase and Mike and for the nice comments!
Was out last night, had a 'sucker' hole in the clouds for an hour or so but transparency wasn't half as good as the other night.
Managed to get the red channel and it looks like a bit of a repeat night tonight so hopefully will put some colour to this lum and post it.
