Recent Images

We've had a few clear nights in the past couple of weeks and when conditions are good, I'm outside with the telescope and cameras.  I'm going to share a few here, as my facebook friends all seem to like what I've taken.

This image of Jupiter was taken on October 1 at 0926Z.  Seeing appeared to be pretty decent, but a little bit of coma was detected still during a star test around the time this was taken.    I had just had the optics adjusted with a laser collimator, but I have yet to fine tune on a star before this was taken.  I have since tuned out the remaining coma, but I have not has the chance to image Jupiter again after this was taken.

One week later, on 10/8, I imaged the Iris Nebula.  It seems that everytime I've imaged this object in the past, its always been done during a bright moon.  This time I imaged it on a moonless night.  It seems there is a bit more nebulosity than I've captured previously.


After imaging the Iris, I thought I'd take a crack at Andromeda.  I did not spend a lot of time on this, but it seemed to come out pretty decent.

 On 10/9 I imaged 2 emission nebulae.  The first is the Wizard Nebula, NGC 7380 in Cepheus.  NGC 7380 is actually an open cluster, but it is surrounded by nebulosity.
This is a very dim object.  I am surprised to have gotten anything at all from my light polluted sky.  I used 3 minute exposures at iso 1600 with the Digital Rebel on this one.

Just after imaging the Wizard, I thought I'd try the Pacman Nebula in Cassiopeia.  This image fared a bit better.
Although not as deep as I probably could have gotten with 3 minute shutter, I switched back to 2 minutes after imaging the Wizard.  I just wasnt sure what kind of quality I was getting with the 3 minute exposures.  I will have to attempt 3 minute exposures on this one sometime.



Then on 10/11, at 5AM I imaged the Horsehead again.  I wanted to see the difference between what I could get at home versus what I got from Cherry Springs.  I was surprised actually when I processed this one, as there really wasnt that much difference.  I just wonder how much better my Cherry Springs image would have been had my mount been working properly.
