Witch Head Nebula

This is an object that I've been wanting to get for a long time, but havent had the equipment to do such a wide field shot until relatively recently.  The Witch Head, IC2118 is a couple of degrees long, and is extremely dim.

For this faint reflection nebula, I used an Astronomik CLS clip in Canon filter on the T3.  It consists of 25 - 5 minute exposures from my suburban sky.  I could not detect it at all with no filtering.

I'm sure that from a darker site, I would be able to get more detail in the cloud formation, but I was able to get the basic shape.

Orion Nebula and the Rosette

Some new images were taken last night.  We had a nice clear night, which we havent had lately.  I wanted to see if I could capture some of the faint dust around the Orion Nebula with some filters that I didnt have a year ago.

I was able to get some of the dust, but with little detail in the dust.  However I was not even able to detect it before using the filter.

This image was taken with the Astro-Tech AT72ED with the .8 field flattener.

After imaging Orion, I thought I would go for the Rosette a little to the East of Orion in the constellation Monoceros.  I've imaged this one a number of times before, but thought I'd do it again...

Nothing special with this one.  I used the same equipment as I used on Orion.

What better way to start a new year than to wake up at 4AM to take a couple pictures of Jupiter.  I saw a post on Facebook from a prominent planetary imager talking about a newly discovered outbreak.  If I'm not mistaken, this first image captured it.  There is another one in the SEB too, but that one is facing away from this shot.

Sorry the image is a bit soft.  I had problems attaining focus, but I believe he was referring to the bright white spot on the NTB near the CM.

The next image was taken about an hour later, with somewhat improved focus.  Seeing appeared to be decent, but I believe the scope's optics were out of collimation.  I hope I have that corrected now for the next imaging session.

There appears to be more detail on this one.  I am quite out of practice imaging planets, the last one was Mars and Saturn last summer.  I do try to get at least one early Jupiter image every season to see what changes have taken place.  This year, there are some big changes.  A number of belts are becoming more prominent this year.  We should be seeing some really good pictures coming up later in the year.

NGC772, The Nautilus Galaxy

Tried to get a din galaxy, something I havent tried to do in awhile.  These objects typically take a lot of exposures to get them to come out well.  This image however was taken using only 8 frames.  I had clouds move in which cut my session short.

What you see here is a really large spiral galaxy, about twice the size of the Milky Way, but its about 130 million light years away. The light we are seeing left this galaxy during a time when early dinosaurs were roaming the Earth, when the first freshwater turtles appeared on Earth.  The distorted spiral arm was caused by interaction with one of the fuzzy specks to the right of the galaxy, another satellite galaxy.

Various Objects Taken Under City Light Pollution

This post shows that you dont need to have dark skies in order to take decent astro photos.  The location this was taken, the 2nd magnitude star, Polaris was difficult to see.  Areas to the South were even worse, and most of these objects were taken fairly low to the south.

The most southern object was the helix.  These were taken in white light, with a Astronomik Clip in CLS filter.

Sure, its pretty dim, but with a few extra exposures, it can be had a little brighter.

The next object I tried was the Horsehead.  It too was quite do-able from within city lights.

The Orion Nebula is a bright object and is an easy target from anywhere.

The blue dust surrounding the stars of the Pleiades, although quite faint is still within the city dweller's grasp.

The Cygnus Molecular Cloud

A vast area of glowing hydrogen exists in Cygnus.  This image was taken using white light as well as a wideband hydrogen filter.  The small fairly bright nebula in the lower center part of the frame is the Crescent Nebula.

This area of the sky is quite large.  It encompasses the area around the North America Nebula, Pelican Nebula and the Crescent, so this is actually only a small part of the cloud.
