IC 1805, A Portion Of The Heart Nebula, In Cassiopeia
March 5, 2013 at 10:48 am

This is a complete reworking of this image from the last time I posted it. I think the colors are more balanced and smoother, and the stars are much better, though not perfect. It just amazes me how much stuff is in this stellar nursery (particularly the profusion of stars), which in this image is about 70-80 light years across. The Heart Nebula is about 7,500 light years away from the Earth.
Enjoy.

I've been around. I have had some recent illness, and trying to deal with that and move forward with my hobby as well. Big changes going on with the LAS, so busy with that as well. Hope to get some comet pictures either this weekend or the middle of next week, weather permitting.
Thanks, folks.

You should be able to see the last of Comet Panstarrs right now. Comet Lemmon is still high up in your sky as well. It's a pretty bug green right now, though you might need binoculars to see it. Here is a pretty image of both taken from South America last week:

Maybe not my dear orogenicman. at what latitude/ longitude are these at right now??

The Tulip Nebula, or Sh2-101, In Cygnus
March 5, 2013 at 12:25 pm

I finally got this image to look like something. It was a tough one:
From Wikipedia:
The Tulip Nebula, or Sharpless 101 (Sh2-101) or the Cygnus Star Cloud is an emission nebula located in the constellation Cygnus. It is so named because it appears to resemble the outline of a tulip when imaged photographically. It was catalogued by astronomer Stewart Sharpless in his 1959 catalog of nebulae. It lies at a distance of about 6,000 light-years (5.7×1016 km; 3.5×1016 mi) from Earth.
***************************
Other prominent characteristics of the region seen in this image are the dark lanes of dust with scattered ionized gas in a massive cloud of stars that are a part of the Cygnus arm of the galaxy.
The Tulip nebula is in close proximity to microquasar Cygnus X-1, site of one of the first suspected black holes. Cygnus X-1 is the brighter of the two stars (the right star) near and parallel to the top center of the edge of the image. It is the brightest object in this region of the galaxy in x-ray images, though it isn't the brightest object in this optical image.

Panstarr is probably too low on the horizon for you by now, but I suspect you can still see Comet Lemmon. You live down under, right? It should be viewable from where you live. It will be in or near constellation Phoenix on Saturday evening. It looks like it is about magnitude 4-5 right now, so you will likely need binoculars and dark skies to see it. But if you can get to a dark site with binoculars and can find it, it should look very good.

Those coordinates are for where you live? Because those are not celestial coordinates, which is what you would need to precisely locate the comet. You just need to know the general area in the sky to look, and then scan there with binoculars until you see it. Look in the area between Sculptor and Phoenix immediately after sunset on the 9th.
Here is a sky map that should help:
