Because it was such a beautiful evening last night, I decided to take out my 102mm, f7, 714mm fl Explore Scientific and with my ZWO ASI120MM camera, try to get something of the moon and Jupiter. I took quite a few shots of both as it was so pleasant outside. Here is Jupiter with Ganymede's shadow on it using Registax6 and Photoshop CS5. I'll look at the moon images later to see how they came out.

Result of using a Duo Band Ha-Oiii filter

Al Ernst writes:  
Club members might be interested in this experiment.

I recently purchased a duo-band Ha-Oiii filter. It was installed on a STL4020cm one shot color camera and used with the telescope at St Joseph HS observatory in Metuchen, NJ where the light pollution yields an SQM of 18.3.

Thus, a worse case scenario.

Images were tried of a star cluster, a galaxy and a planetary nebula ~ M97.
Only the latter came out well.

Club members with DSLRs or OSC cameras might want to give this approach a try.

23x5 minutes
1x1 bin
-20°c
Processed in Nebulosity and Photoshop by Al Ernst and Rick Kelly

Thanks for the heads up Al.
I also read in the current Sky & Telescope that Lumicon has released their "new and  improved" Generation-3 Oiii filter.... and the price seems right too ~ $100 for the 1.25" version and $200 for the 2 inch! Here's Al's image using the impressive duo-band Ha-Oiii filter.   - Keith

Images taken with the 5inch Takahashi in Luna 1 Observatory

Vlad Alexandrov uses the Luna 1 observatory frequently and offered these three images for the blog.

The first image is of the beautiful spiral, the Triangulum galaxy(M33), about 3mil lys away he used over three hours of Luminosity and 80 min Red, 80 min of Green and 80 min of Blue light taken in October 2017. He stacked the images in Pixnsight then processed in Pixnsight and Photoshop.



The next shot is of the Horsehead Nebula, also known as Barnard 33, which is much closer at about 15lys away from Earth and very difficult to see visually, especially here in New Jersey! 
He use 4 hours of narrow band Ha light over many nights due to various weather conditions during November and December 2017. Vlad also used darks and flats as well, stacking it all together using Pixnsight and then processing it in Pixnsight and Photoshop. 




And last but not least; he took this great shot of the even further away Coma Galaxy Cluster, at a mean distance of about 325 mil lys from Earth on January 26th, 2018. He using 3 hours of Luminosity staking with Pixnsight and processing with both Pixnsight and Photoshop.


This is impressive work Vlad, thank you for sharing!

The California nebula with a surprise!

Al Ernst took this image of the central area of the California nebula with asteroid Semiramis entering at the lower left.  Semiramis shows as a small streak in the lower left quadrant (at the left end of my red line).
  
Al tells us further that: "Semiramis was the much revered queen of Assyria who may have built the Hanging Gardens of Babylon".  
The image was taken with NP127is, QSI camera, and H alpha filter from Bridgewater, NJ.

 Thanks Al,
Keith

Threading The Needle (Galaxy)

At 10:40pm EDT on April 28, 2019, long-time member Perry Arts was imaging in his backyard in Branchburg, New Jersey. He was taking a series of pictures of the "Needle Galaxy"/ NGC4565 when an airplane tried to improve his view!
Here's the result:

The plane's presence kept Perry from trying to post process the image further, but he thought that "sometimes the fates align", so he presented it at the club's Astrophotography/Research meeting last week and everyone loved it!
After all, he said, "what are the chances that he would capture a fast moving plane precisely at that very a small part of the sky and be perfectly aligned with the galaxy"?
We all couldn't agree more, so here it is....
Hopefully Perry will send the finished image of the Needle so I can post it here with his artsy photo.

(PS ~ we think the two red "things" are the twin jet engines lit by the flashing red light.Unless, of course, it's the USS Enterprise NCC 1701-D entering warp!)

2019 Lunar Eclipse of the Super Blood Wolf Moon

The January 20-21, 2019 Lunar Eclipse of the Super Blood Wolf Moon occurred almost at the zenith from my house in New Jersey. It also was a bitterly cold night of 13°F and wind chill of 3°F!
My goal was to get shots through the eclipse but my poor hands made me rethink that!
Here's the series of shots and exposures taken until my fingers warned me that if they fall off they will shatter, ending any further plans I may have of ever using them again in the future.
So I stopped at 23:50 20 Jan 2019.

This is an excellent shot (below) taken by Al Ernst of the same eclipse from his backyard using a 400mm Takumar lens and Canon 6d camera.

Thanks Al,
Keith
Another Tim Schott image. Well Done! I'm looking forward to more images taken from your new home observatory....
