Barnard 150 is an interesting dark nebula located in the constellation of Cepheus.

This is more than 7 hours of exposure taken with my AP 130EDFGT at f/4.7 and an unmodified Nikon D5300 and a modified Canon 600D.

There’s also some stars recorded in the field, the faintest of which is magnitude 8.7.

This is a single 1 second exposure at f/6.5 at ISO 200 at 420mm of focal length.

The exclamation point is the new period!

HDR Solar Corona

This high-dynamic-range image of the solar corona that includes about 16 seconds of total exposure took 18 hours to process manually.

http://www.astropix.com/2017_Total_Solar_Eclipse_Corona.html

Click on the image or link to see a larger version with more information.

It is a composite of 14 exposures from 1/4000th second down to 2 seconds at one-stop intervals.

It was put together with special sharpening techniques to reveal detail in the corona.

My latest book, "A Beginner’s Guide to Astronomical Image Processing", has just been published!

http://www.astropix.com/bgaip/bgaip.html

It is available now for download at a special introductory price of just $29.95. After May 1, 2017, it will be priced at $39.95, so don’t delay – order now!

It will teach you how to process your long-exposure deepsky images to produce beautiful results.

Taking the image is just the first half of the job. Processing the image is the other half.

This book is written in HTML5 with Responsive Web Design (RWD), the format used for web pages, so it can be viewed natively on a variety of devices such as Windows and Mac desktop and laptop computers, iOS iPads and iPhones and Android tablets and smart phones.

And now for a blast from the past.

Today is the 20th anniversary of Comet Hale-Bopp’s (C/1995 O1) perihelion, or closest approach to the Sun.

I’ve put together a layout of pictures with a couple of my best photos from that apparition.

I don’t know if you remember that comet, but it was really something!

These were shot on film. I don’t know if you remember that either... :-)

A comet, a planetary nebula and a galaxy walk into a bar...

http://www.astropix.com/Comet_41P.html

Here's a shot of Comet 41P/Tuttle–Giacobini–Kresák passing near planetary nebula M97 and galaxy M108 in Ursa Major on March 22.

This is a composite of 52 x 120-second exposures.

The images were first aligned and stacked on the star background with a Kappa-Sigma average to remove the comet. Then they were stacked again with the same Kappa-Sigma average, but this time they were aligned on the comet to remove the stars. The results of both stacks were then composited together in Photoshop.

NGC 5033 and NGC 5005 make a nice pairing of galaxies in Canes Venatici.

http://www.astropix.com/NGC5033.html

This was shot over the course of two nights at the end of February and beginning of March this year.

A total of 6.66 hours of exposure was taken through an Astro-Physics 130EDFGT working at f/4.7 with an AP 0.75x focal reducer. An unmodified Nikon D5300 was used for the lights at ISO 400 with only bias frames for calibration. Images were Kappa-Sigma average combined in DeepSkyStacker and then the color, contrast and brightness was enhanced in Photoshop.
