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.

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,

Keith

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,

Keith

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...

Keith




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.
