Sorry no imaging from Rott’n Paws this morning, however visual observing of the morning planets has been going on.  Thursday was very, very good – but those pesky clouds made it difficult, sucker holes at best.

 

Friday morning was very clear, but the seeing was horrible, could barely see the cloud bands on old Jup.

 

This morning, OMG!  It was clear, steady and very transparent.  As soon as Jupiter cleared the trees at about 5:15 it was spectacular.

 

Saturn when she finally got above the trees was equally as stunning.

 

Eventually Mars jumped out of the top of the trees and was very good as well.

 

Jupiter was the “star” this morning though.  All four Galilean moons were visible as spheres in the 18”.  The GRS was in the top most cloud band and very distinct fully RED.

 

What was of significant note was the lower cloud band.  It had a very odd visual feature.  It took me most of the morning to get a good grasp on what it looked like to me.  First of all it was blue or a very dark blue.  When I first spied the feature, I thought two different moons must be transiting and I was seeing their shadows on the cloud tops.  Mr. iPad told me that was not the case, there should be no transits ta this time.

 

I fiddled with different eyepieces varying the magnification from 730x, 438x, 313x, 244x, 183x, 156x, and 129x.  The best view while it was relatively dark was 438x.  With this I was able to ascertain that these two blue round spots on the lower cloud band were actually connected through a faint blueish arch.

 

While I am by no means an artist, with the help of my Yeti cup I drew a circle to represent Jupiter and then sketched in the two cloud bands and the GRS.  I drew the above described feature, but it was much more faint than how I drew it, and the left hand portion of the arc was more angular in the eyepiece.

 

Anybody in the dawn patrol image Jupiter this morning?  Perhaps caught an image of this feature?

 

On another note, tried in vain to get Mercury…

Ian...you just wrote the story of my 'imaging' life... "moon up clear skies, moon down - clouds" ....

Tks,

Hey Stu good shot. I'm struggling to find Ha targets with the moon. It always seems to happen - moon up clear skies, moon down - clouds.

Got a few minutes out last night and spent some time with The Tadpoles. Only able to salvage a few Ha frames due to Moon, passing clouds and an occasional gust of wind. Not enough SII and OIII frames made the cut to be worth while...Maybe another night! Just excited to see some stars again since about the first of March.

Re: Sun Activity

Been watching it for the last two days. Best in a long time. Other highlights: Venus Pleiades conjunction tonight and tomorrow. Three planets in the early morning in the southeast. I was up at 430 to catch those yesterday morning. Look at Venus tonight at twilight in a wide field.

If you have Ha capability, have a look at the sun. Very large prominence is evident!

I looked up the astronomer, Yuri Beletsky.  He's with the ESO in Chile at Carnegie Los Campanas observatory in the Atacama.  The images were taken with a relatively small telescope, then a year to process.  More info here:

Yeah Bob...I think it did say that it was multi years and it was 1400 images put togather in a mosaic. I think I figured it out correctly the other day and if my math is correct it comes out to about 10 minutes an image, (using rough figures about 9.8 minutes). That is about what a lot of images use for such bright areas of the sky. Also using ordinary software that could all be automated by programing so you could sleep thru the whole thing. Processing, on the other hand, would be a bear of a job. The same software would assemble the mosaic with the correct overlap and correct background colors.

Galileo started the image back in 1637. He became an imager after he went blind.

What a great overview. Often observing with a telescope you cannot get an overall big picture setting.

Oddly I have found that 20x80 binoculars in a dark sky reveal much that is hidden by using a telescope. The margin of Barnard's Loop is dead obvious in binoculars. Totally hidden in a telescope.  There is an open cluster that is perfect for seeing the boundary of the large loop. Using this as a guide in a small telescope sets the context.

Seeing M-78 in a telescope is interesting but seeing it in a wide field view is revelatory. Without an understanding of the background, the details are always incomplete and deceptive.

It is trend, understandable, for larger and larger telescopes with narrow fields to be used as primary observation tool. They do reveal details and faint objects that only a large aperture can do but they loose context due to design. Try looking at the entire Veil Nebula in a three inch telescope under a dark sky with a wide eyepiece. It puts it all in context.
