Simulation of Jupiter's October 12, 2013 TRIPLE TRANSIT

Using screen captures on Grischa Hahn's WinJUPOS (http://jupos.privat.t-online.de/) I put together this animation.  Starting at 20131012 0315UTC and ending 0815UTC this animation steps through in increments of 15minutes.

During the "Triple Transit" we will see three shadows on Jupiter's disk at the same time.  The shadows of Io, Europa and Callisto will all fall on the visible side of Jupiter at the same time.  After the shadows of Io and Europa move off the edge a true double transit will take place.

These events are rare so go out and enjoy this one, I have never seen a triple transit since I started to observer Jupiter back in 2007.

All times are in UTC and you will need to convert to your local timezone.  I hope these screenshots and animations help your planning efforts and clear skies to you.

Around Abell 262, a galaxy cluster in Andromeda

Abell 262 is a cluster of galaxies that are part of the Pisces-Perseus supercluster and approximately 205-250 million light years distant.  I cannot find good information on how many member galaxies are included in this cluster.  I set out to work on some deep sky object imaging fundamentals.  I started imaging the bubble nebula (seen here)  Then I moved to another part of the sky and I'm not sure why I did it but found all these tiny galaxies using my star charts.  In awe I took a photo and found as many galaxies as stars.  Flashforward weeks later and I finally get around to learning more about this fascinating part of the sky.  I imaged a part of the sky near, but not including Abell 262.  Here is the full view of a mosaic of two separate areas.  All told I estimate that there should be near 76 or so galaxies in this one mosaic image of 2 sub images.  Some  have distance/redshift measurements some do not!  Read on for some mind blowing facts!

And the glorious 15 MegaPixel view (Scrolling required)

Here is a labeled view, where each red area/dot is a galaxy!

------------------------------------------------------------

Now let's take a look at some close ups of interest. 

In this subarea, there is approximately 30 galaxies.  Use this mouse over for details.

Along the top of the full image is my favorite is this area, which includes the most distant object I've observed to date.

This one struck me with the different sizes, shapes and types of galaxies all in one area.  This field covers 10 galaxies in an area of about 13.5 arc minutes wide.  Of all of these galaxies I think I love the barred spiral on the right and the tiny spiral above the A in Abell on the bottom title bar.

Here is the mouseover to help find them.

Now for some mind blowing details....

-------------------------------------------------------------------------------

This happenstance image with some fact finding of my own includes the furthest object I've yet observed.  Let's see how I came to this conclusion.

My references to imaged fields are plate solved and overlaid in Cartes Du Ciel via the solved fits wcs header info.  Then using the CdC PGC catalogs I can reference the v (velocity - http://leda.univ-lyon1.fr/leda/param/v.html) information, typically expressed in km/s and measured via 'Compilation of cz (radial velocity) measurements' (http://leda.univ-lyon1.fr/leda/rawcat/a110.html)

Convert velocity measurements into redshift (z - speed of light in vacuum):

http://www.convert-me.com/en/convert/speed/km_sec.html

Convert z to distance in light years:

http://www.convert-me.com/en/convert/length/auredshift.html

For example our 'fastest receeding' or furtherst galaxy, PGC197602, is measured at 35444 +/- 36 (http://leda.univ-lyon1.fr/ledacat.cgi?o=PGC197602%20)

35444 km/s = 0.1182 (z)
0.1182 = 1,628,000,000 LY or 1.628 BILLION Light Years away from Earth.

You could compare this to the age of the Universe's expansion, 13.8 Billion years (http://en.wikipedia.org/wiki/Age_of_the_universe) and claim it to be 11.79% of the most distant objects yet known.  Think about that.  From the comfort of my home I can use tools to witness the photons leaving millions of distant suns at a time 1,628,000,000 years ago!  Well, plus or minus 1,654,000 years that is!

Concidentially nearby to this galaxy is, PGC: 3626780, which has no measured magnitude or redshift values. Not that I'm going to purchase a spectrometer but if anyone has one that they think would help measure these objects I'll willingly give it a try.

Jupiter 2013 is off to a good start...

And my automated processing is coming along nicely.  Here's a preview of the v10 routine using python and sikuli to batch the captures from AS2 to AstraImage to WinJUPOS

Here's to a good 2013/2014 for Jove and Mars!

Cat's Eye in HaRGB

I'm pretty happy with this one and for once the weather cooperated a bit!  In between some violent, flooding t-stroms I caught a whole night of goodness.  Here's the Cat's Eye, a planetary nebula that I shot in Ha + RGB.

EDIT: Astrobin has the full res for you, Google does NOT!

Also from this night are some iffy looking bubble nebula shots

I really didn't plan to take a specific object really just enjoy the weather and practice shooting.  Thanks for reading and enjoy the views

Neptune 2013 - 3hrs past opposition

I honestly have not been afforded the time or clear skies to be choosy about when and how I shoot the night sky most of this year.  I had intended to share Neptune with the +Virtual Star Party again this past Sunday, but it was not to be so, the clouds called me inside again.  I did get a break the night after, Monday, August 26, 2013.  Shortly after 1am or Aug 27, 0400UTC, I took this shot in very poor conditions.

If you pay attention to the star, labeled Collimation / Seeing in the lower corner you might notice that there is NO airy disk around the star.  A 2x series of collimations via catseyes and a round defocused star was best I can do.  This lack of airy disk is most likely the result of having quite poor seeing.  The star was jumping all over.  It was a dimmer star and the exposures were consistent or just faster than the planet Neptune itself.  It does reveal a sharp contrast between the resolved 2.4" disk of Neptune and the point of light from the star.

I was unable to get Triton due to the increasing cloudy and soupy skies.  And now back to our regularly scheduled M-Cloudy and 50% chance of rain!

Here is the growing list of all Neptune's I've ever shot.

And shout out to +Universe Today and +David Dickinson  for some Neptune info on opposition and finder charts!

Pluto 2013

If you didn't know it has been a terrible season for astronomy in the mid Atlantic USA.  I purchased a new CCD, but that had nothing to do with the bad weather!  Despite the weather, I managed to catch Pluto 3x times.  Overlayed on this animation you can see the movement from July 22 to July 26.  The middle and last frames is from the 25th and 26th respectively and only 24 hours of movement.  I cannot say for certain but I think if you imaged Pluto over an hour or two you could see movement against the background stars.  I hope you enjoy this animation and I only wished the weather allowed me to share with the +Virtual Star Party

Individual nights capture details are as follows.

Night 1 (top position is from July 22:
 3 x 60sec = 3min

Night 2 (middle position is from July 25:
 10 x 60sec = 10min

Night 3 (bottom position is from July 26:
 8 x 60sec = 8min
 +
 6 x 120sec = 10min
=================
20min total



And the rest of my Pluto captures from all years.

Back at the clearing of the summer back log - day 7

Yet another object I've already shot.  Here is M102, a small, edge on galaxy.  This time I decided a side by side comparison as it was taken with the same scope and different cameras.  The canon 7D is on the left and the SBIG STF-8300M on the right.  They were taken in different conditions and different nights.  Things that jump out at me are the image scale on the Canon is larger as it's 0.55''/pixel whereas the SBIG is 0.7''/pixel. Also, the Canon 7D is shot in bayered color mode and the SBIG being monochrome is only shot in clear / luminance channel. The other thing to note is that the integration time is quite shorter on the SBIG. You be the judge.  

Here's the recent work on M102

And the old shot

And the side by side

Not meant to be a real or honest comparison, just my happenstance results.
