Colors and Shadows of Dust with Lodestar(Live)

 

Below is a capture of the colorful reflections and dark shadows of dust in the Antares / Rho-Ophiuchi region from yesterday night with my Lodestar x2c and LodestarLive v.0.11.

Attached File  Colors.of.Dust_vert_2015.4.21_00.40.37.jpg   123.67KB   3 downloads

 

The double star on the bottom left is 22-Scorpii, the triple star on the top right is Rho-Ophiuchi, the black areas are part of the Barnard 44 dark nebula. The orange glow in the lower part of the image is a result of reflections from Antares that is below the image frame, outside of the field of view.

 

The optics used is a 135mm SCM Takumar lens at f2.5 with an UV/IR cut filter. The exposure was 30 seconds.

 

Clear Skies!

Hi All,

 

Here's a few captures I got last night at the Mauna Kea visitors center with my portable setup and the Lodestar X2 mono and NB Ha filter.  What was interesting was that were a number of visitors there who stopped by to see what I was doing and really enjoyed the computer screen views of the emission nebulae I was viewing.  Many liked it better than looking through the scopes they have set up there.  The MK VIS doesn't use EAA, but I think it would be a big hit.  Later after things cleared a bit, I got these captures.  The Running Chicken Nebula is one I haven't seen before.  

 

Don

Don,

 

Great shots ... and I have to keep reminding myself that they're take with "just" a 50mm scope.

 

With astronomy outreach I find that while there are always a few folks who appreciate the eyepiece view the vast majority seem to connect far more readily with a live view on a screen. You have to be clear about what is going on but as soon as they understand that you are not just displaying some static image pulled up from the internet they seem to buy into the EAA concept. Especially if you have another scope for the simultaneous live eyepiece view. 

 

I find EAA generates much more conversation and a far more positive initial experience than the eyepiece. "That's so cool", and "That looks so much more like what I was expecting" are the most common comments I usually get.

Thanks, Mark.  Appreciate your comments.

 

I had the mini scope mounted on my Meade LS8 with an eyepiece in it.  Some people thought I was getting the screen image from the 8".  When I explained that it was the little scope, they were amazed.  I think I'll speak to the MK VIS people to see if we can do this on a regular basis.  They have over a hundred people a night come out, and being able to see DSO's in this detail will compliment their already excellent program.  Together with what I've seen others on CN, NSN and SGL do, EAA has a great future for outreach.

 

Don

Below is my newest attempt to capture the elusive colors and shades of the dust in the Antares/Rho-Ophiuchi region.

Attached File  Rho.Ophiuchi_85mmf2.8vert_2015.4.23_01.15.12.jpg   143.07KB   0 downloads

This is a wider but shorter shot: 20 seconds with a 85mm SMC Takumar lens stopped down to f2.8.

In addition to 22 Scorpii and Rho Ophiuchi, this field also includes Sigma Scorpii in the lower right.

The orange illumination comes from Antares and the black spots are part of the Barnard 44 dark nebula. North is up.

The camera is my usual Lodestar x2c with LodestarLive v.0.11.

 

Clear Skies!

Nice capture Maurice ... any idea what the magnitude of E is in the 20min exposure?

Thanks Mark but no - I can't provide fainter mags but others on SGL in thread have marked some mags. However in one example (star/gx duo) lower left no mention is made of the star! And stars record easier than gx :-)

To add some jazz to the otherwise color deprived galaxy season, I include a sequence of multi-spectral images of the carina nebula ranging from the green if pure Oxygen-III to the red of pure Hydrogen-alpha. Due to file size limitations, it will stretch over two consecutive posts.

The captures were made with a Nikkor 180mm lens, Baader 7nm and 8.5nm Ha and Oiii filters and Lodestar x2c. H-alpha frames were added in 2.5sec increments. The superposition of the frames were made possible by the unique and excellent stacking routine built into Paul Shears' free LodestarLive program. (The last frame is from an earlier night as after image #6 my mount hit the tripod and needed a meridian flip.)

Hi All,

 

Had a good night last night viewing galaxies with my Lodestar, and it got so late I was able to see some old friends.  I switched to my wide FOV set up with the NB Ha filter.  I had never seen these in such a wide view, and it really gives a different perspective of them.  The Trifid is a bit small, but includes M21.  I included a screen shot of the Lagoon because some LS users had asked about my settings in LL.

Nice shots Don!

 

You seem to have stayed up until the end of the entire summer...

Thank you for including the screen shot with your non-linear settings.

 

Clear Skies!

Images from Astrogates NSN Broadcast 4/24/2015, with his permission.  The Integration information is noted on the top left of each image.  These are screen captures, so resolution is what is it.

While solar broadcasting this past Saturday on NSN I came across this Prom that totally took me by surprise.  I thought I would share it with the group.  The image is a single frame screen capture without any processing.  The equipment used was an 80mmED @f7.5 fitted with a chromosphere Quark and the camera was a MalinCam SSIc with an IR filter and approximately .4x focal reduction all on top of a MiniTower Pro.
