General / Re: Is your weather off, this year?
« on: January 08, 2013, 12:29:02 PM »
I'm blaming it on the Mayans...

Seriously though...yeah it seems to be strange here as well.  This week we are supposed to get in the upper 60's (and perhaps 70) with THUNDERSTORMS!!  Sounds like Spring - and the prediction is 2-3" rain in as many days!  But the long-range forecast is calling for some incredibly cold air to pour down (they are talking single-digits - highly irregular here).

Hey Bob - oh I have a solution for your framing!!  Flip the filter over to L and frame with it.  When you are ready to go, flip back to Ha and take off!

Outstanding Bob!!  The new rig looks great and you appear to be well over the learning curve!

That looks great Les!  Lots of really interesting nebulosity (out wide) that isn't normally seen!

That is very bool Bob!  We were setting up a few weeks ago, when the Geminids were peaking, and I got to see a VERY bright one that lasted a good 2-3 seconds...slow mover too.  Unfortunately T missed it.  Those are great moments!

Very nice David!!  Love the wide field presentation - lots of outer nebulosity.  Wonderful detail too, and the tadpoles show up very well!
Mod HST looks great on this one too.

Image Challenge / Re: Extend the December 2012 Challenge?
« on: December 28, 2012, 04:18:39 PM »
Looks like we'll extend the challenge to January

74
Thanks Bob!!  The 30min. subs were nerve-wracking to say the least!

75
It actually doesn't look like "blooming" in the traditional sense... it looks more like a pimple on one side of the brightest stars.  It will be on the same side of all of them too (in our case, it's always on the right side)

76
Thanks David & Eric!!!

@Eric - we noticed what we could best describe as "horizontal blooming" in our QSI583 (KAF-8300 sensor).  A quick internet search confirmed what we were seeing.  Here is a write-up by Bill Shaheen, where he did some experimenting on the subject: http://theworldofastronomy.blogspot.com/2011/05/horizontal-blooming-in-kodak-kaf8300.html

77
Here is the result of our latest endeavor - M1 The Crab Nebula.

Taken with our 8" EdgeHD at f/10 and QSI583wsg.  This is the first time we've tried 30min. subs!  4hrs. each in Ha, OIII & SII all binned 1x1.  We generally bin 2x2 when using the Edge @ f/10, but noticed what looked like horizontal blooming.  Turns out this is a known anomaly with the 8300 sensor when binning > 1x1.

Anyway, here are the results - click the images for larger views with full details.  Thanks for looking!!

Image Challenge / Extend the December 2012 Challenge?
« on: December 18, 2012, 10:01:11 AM »
Wanted to get an idea of everyone's thoughts about extending the December Image Challenge through January...
Not sure if folks are getting enough time to spend on the challenge with the holidays.

Respond to this thread with your comments...

Mounts / Re: Help with my Atlas
« on: December 10, 2012, 08:40:12 PM »
Hi Roberto - I see no reason you couldn't get 30min. guided subs.  We get 20min. guided regularly with just a quick polar alignment and have round stars.  If you go the extra mile and drift align, you most certainly can go 30min.

Eccentricities / Re: Will I Ever Image Again?
« on: December 10, 2012, 02:12:00 PM »
The thing I fear the most,
Our skies will never clear.
Last we imaged was a ghost,
Maybe I'll just drink a beer.

We've spent all these bucks,
To capture images of the night sky.
Dang this weather sucks,
I may just break down and cry.

One night the stars will shine,
Of this we both forsake.
But we seriously must draw a line,
Our backyard is not but a lake.

Challenge Rules:

1. Objects are to be captured and processed entirely by the user.  Equipment on loan to a user is allowed providing the rig is setup and aligned by the user and the target is acquired, framed, focused and captured by the user.  Internet and/or rent-a-scope remote imaging services are not allowed.

2. Data acquired 90 days prior to the challenge deadline may be used to create the entry.

3. Images are to be posted to the corresponding monthly thread with max dimensions of 800 by 800 pixels.

4. Images must be in jpeg format and may not exceed 1 Megabyte in file size.

5. Images must be attached to this challenge thread.  Direct linking to an image on a server is not allowed.  However, adding a link to a larger image is allowed.

6. The contest will run from the 1st of the month to the last of the month and submissions are due by 11:59pm est.

7. Once an image has been posted to the monthly Image Challenge thread, it is considered final and can not be modified in any way.
