Pleiades and California Nebula widefield

A widefield image of the Pleiades and California Nebula taken with a Canon 550d 50mm 1.8 II lens at F/5.6 and ISO 3200 95 2.5 min. subs were registered and median stacked in Deep Sky Stacker, and processed in Photoshop CC

Tim's image of the M1 Crab nebula

Tim Schott took this image a couple nights ago when it was nice and clear as well as surprisingly warm for the season. The colors came out very well. 

Solar Test Using new Point Grey CCD Camera

Here's a stack I made of a Ha test that Vladimir Alexandrov did before I got to the observatory on the 18th.
This image has very fine detail right from the camera, making it easy for me to combine the images.
This is the same prominence mentioned in my previous post.... just some hours prior.

Huge Solar Prominence

I went to the observatory today to pick up a Ha scope for my outreach at a local high school this coming Tuesday. There was a huge QO team (8 people!) with all the solar scopes already outside showing the public the sun between clouds. It seems we have a lot of excellent new QO's in training.

When I looked through the 90mm Ha scope I was amazed to see this massive prominence coming out of sunspot (probably will be given #2436... it wasn't yet numbered at the time of this writing) and then crossing the limb to retreat back into the solar chomosphere on the back side. 
Beautuful! That view from the 90mm Ha filter on the Teleview 80 is v-e-r-y impressive.
I plan to have my 102mm ES with a Lunt Solar Diagonal alongside this scope for the kids.
It's supposed to be a nice clear day, but I'm still keeping the fingers crossed.
I took this image with my Samsung S5.

Tim Schott made a great SHOT!!!!

Here is an image he took this past week of NGC 891, a galaxy about the same size of the Milky Way and around 30 million light years away in the constellation Andromeda. His PHD Guiding software appears to be doing a fine job giving nice round stars for ten minutes on his mobile setup (INSIDE New Jersey for cryin' out loud). The dust clouds that block much of the galaxy's light are distinctly visible.
This is an great image for an 8" scope..... compare his image to the one at the bottom with 12x more time exposure and probably from a darker sky site. 
Excellent work Tim!
You've come a long way in a short time.

INSTRUCTIONS: For Re-calibrating Luna II

We all Make mistakes, weather it be forgetting to turn off the coffee pot, spilling a drink, or not hibernating a telescope. So if you have crashed Luna II or are going to use it and think you may, this is the instructions for re-calibration of Luna II our second largest telescope at NJAA.

So, you've crashed Luna II or you showed up and it was not calibrated, but don't worry this will only take 10 minuets or so! If you are already familiar with Celestron's three star alignment, don't Read any further, because you already know how to align the scope.

Step 1: Switch Position. Select a three star alignment using the 6 and 9 keys to scroll. It will now say "SET SWITCH POSITION". Press "ENTER" the telescope will now slew to the polar north. Since  Luna II on a permanent mount, it is already polar aligned, so you can just say "ENTER or ALIGN" to that; keep in mind that the Celestron paddle has instructions scrolling on it all the times and press the keys it tells you to!

Step 2: First Alignment Star. After you have completed the first step you should be on a screen that says "SELECT FIRST ALIGNMENT STAR". Using the 6 and 9 keys, scroll through the list of stars and pick a bright one or a star you are familiar with. Since this is the first star, the telescope will be considerably off mark. Use the attached Telrad finder scope and center the star with the arrow pad on the paddle. You can change the slew speed by pressing "RATE" and then the number you want. Usually I use speed 9 for centering the object in the Telrad, and 5 for fine adjustment in the eyepiece; anything below 4 is so slow that the movement will be unnoticeable- even at 3910mm! Once the star is in the center ring of the Telrad, it should be in the eyepiece. Center the object in the eyepiece in the same manor that you did with the Telrad, but with a slower slew speed. When you're done press "ALIGN"   

Step 3: Second Alignment Star. The procedure is the same as the first alignment star, but the telescope will be more exact, the Telrad may not even be needed. please REMEMBER TO TURN OFF THE TELRAD, because its annoying when you show up and the thing dosen't work!
When you're done press "ALIGN".

Step 4: Third Alignment Star: The procedure is the same as the Second alignment star however it should be pretty close to centered in the eyepiece. Center it and press "ALIGN". now you can press "UNDO" until you are at the main "CGE READY" screen, unless you want to add more alignment stars.

Congratulations! You Have Successfully Realigned Luna II! Now go go browse the cosmos with Celestron's most advanced mount and telescope!  Thanks for Reading,
Judson Graham

Lunar ~ Venus Conjunction was on 10 Sept 2015

Opps!
I almost forgot to post my shot of the conjunction of the Moon and Venus last week.
I was staying at the shore in Ocean Grove, NJ when I remembered the event was early that morning of 10 September 2015.
I ran outside and it looked great so I used the only thing I had to capture it ~ my phone camera...

Solar Activity Is Moderate

The Sun is currently in Cycle 24 and moving toward minimum which should happen around 2018-2019. We are still in the maximum half of the cycle but the sun seems a bit under-the-weather so to speak....
For those AstroPhotographers that like imaging the sun, a great link to identify the sunspots is: 
www.solarham.net/regions/september2015.htm

Moderate size sunspots 2415 & 2418 are approaching midway through the face of the sun at this time while 2414 is soon departing. I took these two days ago so it has rotated a bit from these images.

Sunspots 2415 & 2418:

Sunspot 2414:

White-light solar imaging is easy and fun so start imaging....
