Wide Field Imaging In a Local Park In NJ

 Hillsborouugh Township. NJ is very supportive towards our use of the parks for astronomy and imaging. They let us use them after dark and in the past, I've had star parties with sometimes with as many as 120 members of the public showing up.

Recently, I used the darker skies with NJAA members Kah-Wai Lin and Len Cacciator to practice setting up our new equipment... I'll post images as they are taken.

Below: Kah-Wai is setting up his new Williams Optics 51mm and guide scope to his Sony Z6 for a shot.

Below: Len Cacciatore is polar aligning his AVX mount to his new Canon.

New member and professional photographer, Kah-Wai Lin's first attempt at imaging Mars

 Kah-Wai and I spent the early morning hours of 10 October 2020 in NJAA's Luna 2 observatory imaging Mars. Here's his Mars Portrait using the club's 14" Edge.

Thanks for sharing Kah-Wai.


Another attempt at getting better omages of Mars

 Taking good planetary images is much more difficult than I thought....

Here's my 6 October 2020 attempt and the post I put on my Facebook page. Not great but possibly better than my previous tries.

 Friday night, Oct 2nd, I got my camera out for a very close Lunar/Mars conjunction ~ only about 1.5° separation. I took these shots only 26 minutes before the actual conjunction.

Also, the moon is 98.52% illuminated, so it's just past it's full moon stage and on Saturday the 3rd, at about 2pm EDT, it will be at it's furthest distance from Earth in it's slightly elliptical orbit, at 406,282km or 252,451.9 miles.

NJAA Tonight - "Astrophysicist In The Making : A 17 Year old's plan for...

As a follower of this blog, you probably remember that NJAA hosted a party last year for Life Member Mitch Revoalski after he achieved his Doctorate in Astrophysics....  Now NJAA is proud to have student Athena York Basu discuss her love for astronomy and her future plans in astrophysics in a video streamed from the NJAA website on September 26 at 8:30pm   (NOTE: this is scheduled for Saturday the 26th of September NOT today as indicated in the link)

 Kah-Wai Lin saw an opportunity during last night's clear sky to test his new iOptron mount with his Sony A6 and Canon zoom lens. It looks like everything worked fine! I think the Pleiades (M45) image was taken at 300 or 400mm focal length using 30 second subs, while the North America Nebula (NGC7000) was taken at 150mm focal length using 40 minutes of 1 minute subs. Although he took a set of darks he said he didn't use them in post processing.

Excellent images Kah-Wai, especially considering these are your first try at "deep sky" imaging.

Thanks for sharing,

New Member Kah-Wai Lin's First Deep Sky "Test" Shot

 Welcome to new NJAA member Kah-Wai Lin. A biologist PhD with research experience at Princeton University, he shifted gears and began a career as a professional photographer/lecturer. Travelling to over 60 countries over the years, recently Kah-Wai purchased a new iOptron Sky Watcher Sky Tracker and while testing it out during partly cloudy NJ skies, he took the image below using his Sony A6 camera and Canon  400mm lens.

I wish my first try at deep sky looked this good!  We can look forward to many more of his images here....  Thanks,

Another great Tim Schott shot...!

 Tim took this great shot of the Cosmic Rosebud Nebula (NGC7129), a reflection nebula in the constellation Cepheus on the night of August 19, 2020

This was taken from his home observatory in Easton, PA, USA
using his 10"Third Planet Optics RC Truss scope on a Losmandy G11 mount with a Nikon D810a camera.

Nice job, Tim...


This is the same shot sent from Tim as he did some more post processing.... I'm leaving the original shot in the post so you can see the difference that post processing can make in astro imaging.
The last image shows that the nebula is actually much more extensive and colored.
Thanks for the extra work, Tim.

About the nebula; it is about 3,300ly  from Earth and is lit by a young open cluster of more than 130 stars. It's apparent magnitude is 11.7, so you would need a telescope to see it. The rosy-pinkish and gray color is probably "from hydrocarbon rich molecular material" while "three very young stars near the center of the nebula are sending jets of supersonic gas into the cloud. The collision of these jets heats carbon monoxide molecules in the nebula."

Comet C/2020 NEOWISE image shows movement over the night sky

Rick Kelly (a NJAA member during the 1970's) and member Al Ernst cooperated on this shot of Comet NEOWISE C/2020, showing it's motion over 2¾ hours. 

Al took the comet's image on the right through a blue/green filter on July 28th at 2:30UTC from his home observatory in Bridgewater, New Jersey while Rick took the unfiltered image on the left from Castro Valley, California at 5:15UTC.

It's a great comparison showing this great comet's movement over the sky during such a short period of time.

Thanks for sharing Al and Rick.

Comet Neowise C/2020 image improved by stacking.

Al Ernst improved his image of Comet C/2020 (NEOWISE) by stacking it in Nebulosity. Taken in Martinsville, NJ, USA with a Canon 6D, ISO 1600 using 12x 15 seconds.
Awesome close up Al, thanks.

N16/NGC 6611 "Eagle Nebula" looks great in NJAA's local area

M16/NGC 6611 - The Eagle Nebula is a star forming region in the constellation Serpens. The gas and dust clouds at the center of the nebula is known as "The Pillars of Creation" as seen by NASA's Hubble Space Telescope's images.
Tim Schott used his 10" Third Planet Optics RC Truss scope with a Nikon D850a on a Losmandy G11 from Easton, Pennsylvania. 
Well done, Tim, looking to see more of your work.

Comet C2020 (NEOWISE) viewed from a Somerst County Park

I took these images from the parking lot of a local park in central NJ... the important feature there is a view all the way down to the western - northern  horizon. Some small bushes block a little view but I think that adds to the photo! I used a Nikon DSLR with a 28 - 300mm lens at 28mm and 105mm. Exposure was ISO 1000, 10" at f5.6 on a tripod and the self-timer.

The Pandemic Has A Bright Side

The Covid 19 Pandemic has had a effect on us all, but Tim Schott shows there is still some beauty in the world with this image of the NEOWISE C/2020 Comet. No details of how he got the shot, but its awesome!
Thanks Tim,

The COVID 19 Pandemic Allows Time For Al Ernst To Get Great Images From His Home

Al Ernst took this image of M63 from his home in suburban Bridgewater, NJ. It's composed of a total of three hours accumulation of photos using Blue, Green and Ha filters with a C-14 and QSI 583 camera. It's amazing that filtered imaging can do in heavily light polluted areas.
Thanks Al

Thor's Helmet, NGC 2359

Al Ernst took this amazing image from the light-polluted suburban skies of Bridgewater, New Jersey. Being a long-time member of NJAA, Al knew exactly how to beat that problem.... by using Ha and Oiii filters he would block out much of that unwanted glare.
He took four hours of 10 minute subs to build up enough photons to produce this amazing image. Al's equipment for the job was his QSI-583 camera and his NP127is scope.
Thanks Al,

The new phenomenon; watch the "Skytrain" pass by your neighborhood...

With more countries and companies launching satellites to get on the new gravy-train, having a peaceful night with your telescopes, watching the stars, will mean frequent intrusions by skytrains sailing past your dark sky.
Here is a video of Starlink in the evening sky taken by member Tim Schott from his eastern PA observatory. You'll need to make the video full screen on a laptop or a larger monitor to see.  The stream is above the trees and below the small star near the center. If you don't see it , try again looking just above the tree line.
Thanks for sharing Tim.

Coronavirus has everyone being very cautious

The NJAA Board Of Governors has decided to postpone any immediate meetings at the observatory. Our one March lecture has been officially postponed and the club's website will reflect the changes and our regularly scheduled summer public Saturday and Sunday tours are still posted as being open. Duty QO's have been (or will be soon) instructed to only let groups of less than 12 people into any of the buildings at one time, favoring loose gatherings.
Obviously time will determine further action. We are optimistic that the onset of warm weather will minimize the effects this virus will have and allow us to return to business as usual.
Thanks for your understanding,
