After A Slow May, M1 Starts June Off With A Winner


Al Ernst was working during January and March's occasional cool, clear nights using his Celestron 14 inch at f8 to get this great shot of M1... the famous Crab Nebula. The Crab Nebula's supernova was first seen and recorded in China in 1054 CE. Since that time, it has grown, spreading out through space to an average diameter of about 11 light-years across. That would make it more than twice the distance from the Sun to our nearest Star system, Alph Centauri!  

He captured its details by accumulating a total of 7Ha and 7Oiii filtered subs, with each sub being 5 minutes long. He used a QSI-583 camera, which was cooled to -30°C below ambient, and processed the image using Nebulosity and Photoshop.

Nice work, as usual, AL. Thanks for sharing.

The Edge-On View Of Galaxy NGC 891

 Recently, Al Ernst was kind enough to send me his work on the "Silver Sliver Galaxy", a.k.a. NGC 891. It's an unbarred spiral galaxy about 30 million light-years from Earth with a diameter of about 60,000 light-years.  Compared to our closest galactic neighbor, the "Andromeda Galaxy" which is about 2.5 million light-years away and about 220,000 light-years in diameter, the Silver Sliver is much harder to see from his back yard observatory.

NGC 891's apparent magnitude is +10.8 is best seen through a medium-sized amateur telescope of about 8" in diameter or more, making Al's Celestron C14 main telescope ideal for working out its details as seen in his photo below. The dark dust lane surrounding the galaxy's disk is easily seen.

The image was recorded earlier this winter from his home observatory in Bridgewater, NJ using his C14 f8 and QSI 583 Camera with Green, Blue, and Ha filters on 5 and 10-minute subs and processed in Nebulosity and Photoshop. Thanks Al.

The Dumbell Nebula M27 In All It's Glory; As Seen Through Clear New Jersey Skies


This image of the planetary nebula M27 (a.k.a. the Dumbell Nebula) taken by Ron Gattie,is about 1360 light years from Earth and at apparent magnitude +7.5 isn't quite bright enough to see by eye ~ even in the darkest skies. 

But the C14 scope at St. Joseph High School shows not problem getting these rich colors even in a Bortle 6 sky. At that distance, the Dumbell appears to be 3 light-years in diameter, or just a light-year short of the distance between Earth and our nearest star Proxima Centauri.

Nice shot Ron.

Al Ernst's image of NGC 1491, located in Perseus

NGC-1491 is a faint emission nebula approximately 11,000 ly from Earth. This image was taken in late November from Al's Bridgewater, NJ observatory, using a C-14/f7.7 telescope, a QSI-583 camera and narrowband Ha and Oiii filters, with one hour of 5-minute subs in each band.  Processing was in Nebulosity and Photoshop.

Thanks for the submission Al,

Al Ernst is getting great results during the winter's cold, clear sky

I love the faint tendrils visible in this great shot of the Horsehead Nebula taken in Al's backyard using a QSI-583 camera, C-14 scope. It consists of twelve five minute subs through each of Oiii and Ha filters,

 I haven't heard from anyone lately so I'll just add a few of my Moon shots that I took before Christmas.  I was rushing to set up the scope in my driveway by the road to get the Jupiter / Saturn Conjunction as the clouds were coming in fast. Low in the sky by the western horizon where the event was taking place was a small hole in the clouds that lasted about 15 minutes. But just as I got it centered in my scope, a few neighbor families and their kids came to see what I was doing. For the next ten minutes I showed everyone the conjunction, to "Wow! I can see Saturn's ring and Jupiter's moons too".

Then it disappeared!

The clouds covered most of the sky, but I spent about fifteen minutes getting these shots of the moon before it too disappeared for the night. Since then only one or two nights were cloudless, with another night that was clear but with a lot of haze.

Al Ernst and Ron Gattie Combined Talents in Capturing The Saturn Nebula

This image of the Saturn Nebula was taken by friends and amateur astroimagers Al and Ron, using two C-14's. One scope is located at the St Joseph High School's observatory, where Ron used a Canon 50D to take 10x30 second subs, then Al combined them with 20 Oiii and Ha subs with his QSI583 that he took from his home observatory about ten miles apart. This shows what amateurs can achieve, even within the confines of a Bortle 6 sky.... using good equipment,skill and practice.

Thank Al and Ron

Prepping for the rare conjunction of Jupiter and Saturn

I took this shot of Jupiter and Saturn on 10 Dec 2020 to prepare for the conjunction at my imaging site at a local town park. Mount set and marked.... cameras loaded and ready... astronomy equipment set aside... Township Parks and Recreation officials notified and attending...  local astrophotographers confirmed... batteries charged... Laptop set to go...!

This part of Hillsborough Township in central New Jersey is out in the country about five to ten miles from any small villages and boasts a wonderful  Bortle 4 to 5 sky! 

Here in this shot, the two planets are moving closer each night and hopefully, I will have everything set up and ready to go before the sun sets on the 21st. Otherwise, I may need to wait for the next time that these two planets will be this extremely close together again! 

Praying ~ No Clouds, No Clouds... NO CLOUDS!!!

Al Ernst's Elephant's Trunk taken in hydrogen alpha

 After seeing Kah Wai Lin's recent image of IC 1396, Al says he was motivated to take a Hydrogen alpha image specifically of  the Elephants Trunk. The targeted area can be seen in the lower middle of Kah Wai's image.  This required stitching together an upper and lower frame, each consisting of one hour of five minute subs.

He used his C14; a .7 focal reducer and QSI583 with narrowband Ha filter.

I find it amazing what persistent people are doing in Bortle 5 and 6 New Jersey!

Kah Wai Lin is making good use of his new astro-camera and learning the use of new software


This image of the Elephant's Trunk and surrounding nebulosity is a reprocessed image using both PixInsight and Photoshop. He says he is sure he will reprocess it again as he is continuing to learn more with PixInsight... each time getting more out of the image.

The Elephant Trunk Nebula was captured using RedCat51 and ZWO ASI1600MM Pro on his Sky-Watcher Adventurer with auto-guiding. The image totals 4 hours (1 hour each in Luminance, Red, Green and Blue). His site in central New Jersey is Bortle5.

Thanks for sharing your progress.
