Adventures in collaborative planetary astrophotography part 2

No, there's no part one per se.  Last January Kevin Quin, a very accomplished astrophotographer had some issues with his color filter wheel.  He lost one filter's worth of data from the whole night.  In is asking around it just so happened that I had my own images from the same date and time.  We're separated by about 235 miles straight line distance but had quite similarly good weather.  His quest to fill the gap in his own data was met with a warm welcome from me.  I always share my data and methods with all and in this instance he rescued his own data with a small help from my own.

Now onto part two: In some odd twist, I suffered a loss of the whole filter wheel itself and not just a malfunction.  I lost the ability to change filters quickly enough for me to shoot a color image.  I didn't think to ask anyone else for other shots of my own missing colors but did think the weather was good enough to shoot at least one color's worth.  Red is always my goto and usually has the best seeing.  I unscrewed the red from the wheel and put it into my imaging train.  It wasn't until many days later that I found Kevin was again out at the same date and time as me!  What luck, he was happy to share his stacks of Jupiter with me and I was able to make this color image.  Using a single stack of Kevin's blue data that he got from a 5min derotated .ser file, I combined with my own Red.  For green I used his blue and my red at a 50/50 blend.  This technique is often called RsGB or a synthesized green (http://www.astrosurf.com/cidadao/red_blue.htm)

I found it amazing that despite our differences in locations, cameras, telescope types, styles and sizes we were able to bring out data together to make great images.

In discussing this type of coimaging work, we can't think of many folks who have done similar work.  Association of Lunar and Planetary Observers (ALPO), BritAstro, Planetary Virtual Observatory and Laboratory (PVOL) and Section Planets Italian Amateur Astronomers Union are all good candidates for such collaborative work.  All sites tend towards gathering images at separate dates and times and using them for study of changes over time or whole planet maps.

What Kevin and I are thinking would be a place to share raw or simple stacked images in an effort to learn and discover.  I'm curious to know what other's think about this.  If folks are interested we can setup a shared file repository and wiki to make it happen.

As a sample here is my raw red frame:

 and Kevin's blue

Special thanks to Kevin Quin for making my image really special!  Thanks Kevin!

2014 Solar System in Review

I can sit and complain about clouds being so bad this year all I want, but the fact of the matter is 2014 was a great year and I'm blessed to spend it with my friends and family!

Spanning from January 4th to December 30th (Never give up!), all photos are mine, including the Earth and all taken within the calendar year of 2014.

While last year was the year of the comet with 4, this was the year of the asteroid for me with over 12.  I say over 12 because as I learned to hunt these tiny and faint things amidst the stars I found some images of poor quality and sometimes iffy results.


Here's the high resolution version on imgur as google shrinks it.

October saw some great clear skies - part 2, the nebula edition

This edition is very nebula heavy.  Nebula are interesting in their aesthetics and beauty but are foreboding, inhospitable places.  In sharp contrast I love galaxies, they're tiny, life bearing universes unto themselves.  They are like turning up a rock and finding varied things of all kinds, rocks, bugs, worms.  Each galaxy too is unique, but i get ahead of myself thats post 3 of my wonderful start to fall deep sky observing!  Also be sure to check out part 1

IC 1848 the Soul Nebula

I had previously shot this area last year   One major difference that jumps out is the B&W vs false color from this year.  The color in all my newer nebula shots is false, created in photoshop where I turn the white areas of the nebula 'red' and the bright stars 'blue'.  The other things to notice are the duration of subs/total as well as the roundness resulting from better guiding, which is a combination of better guide cam and better overall polar alignment techniques.  Also the collimation was a bit better for this years attempt!


Second up is NCC 281 or the Pacman Nebula.

Here's a link to the 1920x1080 wallpaper edition!


Finally batting clean up for round 2 of my fall, clear and deep sky collection...

NGC 1499 the California Nebula.  I think this is the area around the San Francisco Bay area!  :)

Thanks for looking and be sure to check out all my Astronomy related images and follow me on Google Plus, Twitter or Facebook!

October saw some great clear skies -- Part 1

This month was full of many clear days.  I took advantage


First up is NGC 100, which according to http://cseligman.com/text/atlas/ngc1.htm has "a mere apparent size of 6.2 by 0.6 arcmins." It is also described as "exceptionally elongated galaxy, with a very small nucleus in comparison to its overall size. Such galaxies are sometimes called "superthin" galaxies." Nearby is PGC 1509358 a 17.9th mag galaxy.

Also in the lower left is UGC00219 a bright 15.5mag at a distance of 240,700,000 LY



Come poke around the full 1:1 resolution here


Next up is NGC 7814, another edge on galaxy. The one sports a nice dust lane and in contrast to the above galaxy, NGC100, this galaxy, NGC 7814 is a spiral. It "is sometimes referred to as "the little sombrero", a miniature version of Messier 104." (http://en.wikipedia.org/wiki/NGC_7814) Edge on galaxies are very fun and the reddish orange core might be slightly exaggerated in this photo unintentially as I had a color balance issue.






Here's a link to the full 1:1 resolution

In the high res photo, the most astounding thing I've found to date is SDSSJ000302.45 or PGC3377433 in another catalog. At mag 20+ this tiny galaxy has a measured recessional velocity of 115421 km/s in converted distance it's 5.3 BLY away!!! WHAT?!!

Between the galaxy NGC7814 and the three bright starts to its right is the faint galaxy in question. Here's a closer look.

Finally up a a face on galaxy and part of the Messier catalog, M74.  It's two main spiral arms make it a Grand design spiral galaxy (http://en.wikipedia.org/wiki/Grand_design_spiral_galaxy ).

Full res here!!!

A refreshed Little Dumbbell - M76

I had previously shot this target on the same telescope ( +Akule  ) last year but used a DSLR.

Here's my more recent effort with a CCD.

Astrobin has the full 1:1 resolution


The full 1:1, HD (1920x1080) resolution for your desktop wallpaper 

Now for the somewhat unfair side by side CCD vs DSLR

The DSLR, a Canon 7D is on the left from last year.  The new SBIG STF-8300M is on the right.

What is really unfair is that the integration times are MUCH different.

Still to me, there is a HUGE difference and I wouldn't want to use a DSLR as my main camera for this type of work.

The most fun was that I was inside playing games while the image was taken using Sequence Generator Pro and monitored via teamviewer.  The clouds started to pass but the guiding held up so I kept going!

Uranus and 5 moon animation

Taken over the span of 36 minutes on September 28th, 2014.  I was able to image; Titania (mag. 13.9), dimmest Miranda (mag. 16.5), Ariel (mag. 14.4 ~Pluto's brightness), Umbriel (mag. 15.0) and Oberon (mag. 14.1).

First here is the untouched animation showing Uranus at the same exposure of 1sec.

Next I added the color and properly exposed Uranian disk.  I shot at a nominal focal length using the 2.5x powermate and the soon to be older Flea3 camera.  Next time I'd love to get the QHY and 5x Powernate!

Also relevant, my 4 year old sounded out Uranus to...

YOU

RAN

US

I love it!

Also the fact i can image down to 16th magnitude at this focal length has me wondering about splitting Pluto and Charon!

And then there was ONE

I'm rolling through the Messier Catalog.  It's 8 or so years in the works but I now have images of 109 of the 110 objects!  Only one left is, M79 in Lepus the constellation just south of Orion.  I will hopefully image it before the end of the year.

Total list and progress is on my home page - http://maphilli14.webs.com/mike-s-deep-sky-photos

On a single clear night, mind you there haven't been many, I shot 3 more.

Here's M72, which I thought I had shot previously, but mis labled it so I had to shoot it for real this time!

Next up is either an asterism or open cluster, it's listed as both in different places, but M73 is the simple group of 4 stars in the upper right.

 M30 came out very nicely after a few battles with software and alignment issues in the previous two shots.  Here is the full field.  But click here on Astrobin for the full res

Here is the full res cropped at HD res.

While I waited for my targets to clear the trees I found a small group of galaxies, NGC 6702 & 6703.  Amongst them are many other galaxies, mag 15-16+  I found no measure of distance or radial velocity, which I initially found intriguing but am no annoyed I don't know how far away they are!

Here's a overlay with labels.
