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.

The bottom image was produced using a RCOS half meter telescope, Apogee Altra U16M camera ($13K) camera and Astrodon E-Series Filters.

Exposure times: 1,710 minutes Luminance, 120 minutes Red, 120 minutes Green, 120 minutes Blue (all 1x1).

Luna 1 & Luna 2 Current Status

Luna 1 & Luna 2 are operational at this time.

The Covid-19 Pandemic has hurt many people, including astronomers. However, the one thing amateur astronomers are very good at, is being outside ~ alone, in the dark. Then later, often working many hours inside (again, often in the dark) during post processing of any images he takes. With the weather now getting warmer, it is always an ideal time for learning to use a new scope, mount, camera or just looking up for Milky Way objects that you may have not seen in a while. This is the time to explore within our galaxy! There is always so much to see, so still dress warm until the temperature gets high enough for comfort ~ the summer will get here soon and being outside in the fresh cool air can be exhilarating. Then if you haven't already, try taking some pictures of what you see or just look for that new sight that you may not have seen before. For instance, closer to home, conjunctions or the nearness of planets and the Moon to each other as we see them is one of the rarer events that occurs only once in a while and sometimes it will only be witnessed once in a person's lifetime. This is the "Milky Way Season".... enjoy it!!!

Also Luna 1 and Luna 2 are calling for you!

Now that our park has reopened, although slowly to the public, members can always use the on site observatories. Please remember to keep personal distancing a priority and wear a mask unless otherwise specified.

As a strange by-product, the sky seems cleaner and clearer as the volume of New Jersey highways still are experiencing less vehicles than before the pandemic. Even though the bazillion forest fires in California and around the world have definitely added to the high altitude haze. Still, cool, clear nights mean great observing and are more inviting for our member astro-imagers. Especially for those of us that use narrow band filters to cut through any remaining ambient light pollution. As temperatures rise the various air temperature cells between you and the objects in space will seem to be a little less-steady... stars still twinkle ~ an indicator that the sky is unsteady. New Jersey is not known for it's great seeing, but video cameras will help get the best planetary pictures possible after stacking from thousands of short exposure images. Also, try something new like imaging just before dark ~ the reduced contrast makes some interesting planetary pictures. Venus' crescent shapes often stand out better in the low contrast sky.

As the weather gets warmer, be sure to drink a lot of water ~ and of course still wear layers to be comfortable.

The 5" Tak telescope in Luna 1 is now totally automated, with the roll-off roof now motorized. Special training for our members is ongoing and producing great results.

The Celestron Edge 14" telescope in Luna 2 is working well and is a pleasure to use. If you aren't trained for it yet just ask. We'll be happy to teach you.

The Celestron 11" telescope in the Schirra Observatory may be getting a new purpose ~ time will tell.

We want all members to be able to use our other available equipment too, including the roll-out Celestron 8" Edge and C9.25" scopes in back ~ which are also great for imaging planets and the moon as well as the various types of things within the galaxy.. The novice as well as experienced amateur's can use the numerous Dobsonians (up to 12") and are handy for quick observing.

Also, this is excellent time to use the Solar Ha scopes during the day. The surface sunspots seem to to increasing considerably as the sun is now heading toward the cycle's maximum. Occasional larges sunspots and prominences prominences are very impressive in this wavelength. We now have three great Ha specific scopes as well as various white-light filtered scopes.

Finally, remember that the club has a number of excellent loaner scopes (including a go-to) that you can take home for a period of time to learn and practice on.

Take pictures and share your images with the NJAA Astro-Photography blog. Contact Keith at KRMarley_1999@yahoo.com

Also, the large NJAA Library has a number of excellent astro-imaging books for loan, free to members in good standing (a cc will now be required to take a book home).

A link will soon be on the NJAA website home page or ask a QO on duty for help (check the website calendar for public/duty days www.njaa.org) or contact Keith at KRMarley_1999@yahoo.com for library questions.

NJAA Astro Photography Group Mission

The "Astro-Photography” committee has merged with the Research Group, forming one Research & Photography Committee. It shall also be responsible for the administration and coordination of the Astro-Photography program at NJAA.

Through educational events, public outreach and publication, the committee will continue to serve as a technical resource for emerging and advanced Astro-Photographers.

The Astro-photography/Research meetings (currently and until further notice, all member meetings will be conducted on ZOOM. Member requests to be included ARE AVAILABLE ON THE ASTROPHOTOGRAPHY PAGE ON THE NJAA WEBSITE) are held at the observatory on the first Friday of the month at 8:00pm. All members are welcome to attend. Confirm the dates on the club's website calendar (www.njaa.org).
