Latest Images

OK, I admit it... I've been bummed because of the weather we've had for much of the summer.  I have been imaging, but perhaps once every couple of weeks.  Either its just been cloudy, or the evenings have started out cloudy and cleared late at night, and I've just been too tired to do anything with the scope.  I like to set up before the sun goes down, but if it's cloudy, I dont bother.

We have had a few good nights, and I've gotten pictures that I've been too lazy to post here.  This is one reason I put up the facebook page - you'll see many pictures just hours after I take them.  The blog usually goes into more detail about the objects that I image, so the two kinda go hand-in-hand.  If you have a facebook account, I suggest you like the page that that is linked on here to get the full story and a sneak preview of what I'm doing.

Now on with the images I've missed...

First, I'll start off with a Hubble Palette of NGC7380, the Flying Horse Nebula.

This is the one and only image that I've taken using  Oiii, Hα and Sii.  Sii is mapped to red, Hα to green and Oiii to blue.  all 10 minute exposures, 5 each.  This was imaged on 9/5/2013.

A little earlier (8/23/13) I imaged NGC7635, the Bubble Nebula in Cassiopeia.  I also did this in narrowband using 10 minute exposures.  This was shot in Hα and Oiii only.  I created 2 images, one a "realistic" and a false color version.

Here is the "Realstic" version, Hα mapped to red and Oiii mapped to blue and green.

The false color image, with the Hα mapped to blue and Oiii mapped to red and green with different histogram stretching applied to the red and green.  I also took a few star cluster images that evening, but there was haze, and the clusters were far to the south, and were not real impressive.

On 9/10/13, I got an impressive Hα of NGC6888, the Crescent Nebula.  I imaged this one before using 5 minute subs, but this time I used 10 minute subs and the image showed far more nebulosity.

I'm VERY happy as to how this one turned out.  It is one of the deepest images that I've seen of this object.

Then, on 9/28/13, I went to an astronomy club meeting, and the weatherman called for clear skies, so I imaged the Helix Nebula (NGC7293) with an audience present.  This one came out very nice also.

This too has been in narrowband.  Hα mapped to red, and Oiii to Green and Blue.

Also imaged Jupiter on a couple of occasions when the sky cleared late.  this was the best one.....

I have yet to get the more interesting side, showing the Great Red Spot.

Oh, and on 10/1/13, I imaged NGC6946, the Fireworks Galaxy which came out pretty good using LRGB.

On 10/18/13 a penumbral lunar eclipse occured, of which I got a picture towards the tail end of the event.  Note the bottom right is slightly darker, and the moon has a yellowish tint.  I did no color enhancement, only a little sharpening in Photoshop.  I took this using the Canon T3 and 70-300mm zoom at 300mm, f/9.

OK, I think this brings us pretty much up to date.  I did do some imaging, but not a great amount, being this post covers about 2 months or so.  The weather hasnt been that great, a clear night here and there, and its been like that all summer.  I hope this winter, this trend changes.
