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.


This Tulip Nebula Image image was taken by long-time member Al Ernst

This is a mosaic image of the Tulip Nebula (Sharpless 101) taken from Al's backyard observatory in central New Jersey.
Sharpless 101 is a HII region emission nebula located in the constellation Cygnus and is about 6000ly from Earth.
He used a C14 telescope and a QSI-583 camera with a 6nm Ha narrow band filter. Due to the scope's limited field of view he stitched together two images using five minute subs for each.
Thank Al,

Kah Wai Lin's latest image of the North American Nebula

 I know Kah Wai has a new camera and he's been hard at work getting to learn how it handles. I believe this image was taken with his new ZWO ASI1600MM with a new LRGB filter wheel.

Nice results.

Kah Wai Lin's first attempt at LRGB ~ the Pleiades (M45)

 Kah Wai was imaging on the grounds of the observatory during yesterday's late-night hours, taking advantage of the darker skies. He was testing his new equipment and figured out the set up ~  below is his first attempt at LRGB imaging ~  Looks like everything is working pretty well! ~ Keith

Pleiades (M45)
Telescope: Willam Optics RedCat 51
Camera: ZWO ASI1600MM Pro
Mount: Sky-Watcher Star Adventurer
Imaaging and autoguiding: ZWO ASIair Pro
Total Exposure Time: 2.5 hours; 30 minutes each for LRGB channels (10x3min subs)
Post -processing: DeepSkyStacker, Photoshop, NIK Color Efex Pro, Noiseware

Member Max Pike Imaged the Iris Nebula on Oct 17th, Nov 4th and Nov 5th

Located in the constellation Cepheus, the Iris Nebula (NGC 7023) is a reflection nebula, where a close bright star illuminates the gas and dust around it. It's about 1300ly from Earth.
Thanks for sharing Max.

Max's Image is 25x5min L, 20x3min R,G,B
