When a supernova was discovered in NGC 1637 in 1999, it immediately became the focus of very large telescopes...

https://www.eso.org/public/usa/images/eso1315a/

Today NGC 1637 is rarely imaged. Here's one from the Liverpool Telescope on Astrobin...

https://www.astrobin.com/108959/

And from Adam Block in a 16" RC...

http://www.caelumobservatory.com/obs/n1637.html

I was hoping to get somewhere between ESO's VLT and Adam. (-; FWHM on 15 minute subs was around 2.5" these nights, so not the best resolution. But I'm please to be able to extract the very faint spiral arms.


"NGC 1637 is a barred spiral galaxy that lies about 38 million light-years away in the southern constellation of Eridanus (the River). The galaxy is lit by the glow of about fifty billion stars. In its center lurks a supermassive black hole.

In 1999 scientists discovered a Type II supernova in this galaxy and followed its slow fading over the following years. Because of its relative proximity, SN 1999em got bright enough to be seen even with small telescopes, and it became one of the best observed supernovae of its day."

"Solar Storm"

This is a 180° Panoramic Photo with a strong Northern Light, M31, and the Pleiades on the left and Ursa Mayor on the right, the photo was taken during my trip to the Lofoten Islands in February 2019 with a temperature of -16 degrees. Excellent aurora forecasts, intense aurora predicted during late night, perfect for having dinner and leave calmly to take some shots.
With the sun just setting we left our accommodations, we make the first kilometers and we begin to see a green glow that pierced the sky, just started the blue hour, it was obvious that the apps we use for predictions (always very accurate) had missed the timing ... The solar storm was stronger and faster than expected, the sky was literally exploding. Luckily we were driving along one side of a very nice fjord, I quickly found a rest area and got out of the car, 
I have reached the shore of the sea, I thought quickly on the first floor, I saw the mirror on the water and choose 30 seconds of exposure at 1600 iso f2.8 (using my Canon 5d Mark4 with Samyang 12mm f2.8) ... There was so much light that I could read a newspaper quietly, never seen such strong aurora during the blue hour's ending, I was so impressed. Here is also a link to my photo on the website: https://alexwides.com/#iLightbox[gallery_image_1]/4

"The New Year"

This is a 360° Panoramic Photo which I captured during a solo trip to Corse looking for the dark sky of this beautiful island. It is a composite of two different 360° panoramas: one for the sky made during the deep dark with a 6d astromod and an astrotracker, are 8 photographs of 300 seconds, 800iso f/4. The foreground was shot during the daylight at 1/10 of a second, 400 iso, f4. In the editing I did also digital art (bonfire is forbidden in that area, so during the shooting I placed the stones and then I rebuilt it on photoshop). The sky of Corse is really amazing, the cama has captured all the details of the Milky Way and the constellation of Orion, with Barnard's ring clearly visible, surely one of the darkest skies I've ever seen. Here is also a link to my photo on website: https://alexwides.com/#iLightbox[gallery_image_1]/16

Lagoon Nebula (upper left), Trifid Nebula (lower corner) and Loreta Nebula (upper right)

Located about 3,500 light-years away in the constellation Sagittarius, the nebulae are clouds of interstellar dust and gas. Its red glow comes from ionized hydrogen gas and lit by young hot stars with nebulae. The blue part of the Trifid Nebula is a colder cloud of dust that reflects the blue light of the hot stars. Several small, round and dark areas are seen within the Lagoon Nebula. They are known as Bok globules and are clouds of interstellar gas and dust undergoing a contraction phase that can lead to star formation.

Horsehead and Orion Nebula in Narrowband
http://www.woodlandsobservatory.com
Copyright: Alistair Symon This is a 4 image mosaic of the Horsehead and Orion Nebulae taken with a Takahashi 4 inch refractor and an SBIG STXL-11002 CCD camera. Approximately 50 hours of data was collected through H-alpha, SII and OIII filters. The data was combined using the Hubble palette. You can see a larger copy of the image here.

MIlky Way while flying 570mph
www.mdieterichphoto.com
Copyright: Matthew Dieterich Here's a single photo view of the Milky Way setting over the South Atlantic from 35,000ft in an United Boeing 777 when returning from Chile. I had some funny looks hunched over a tripod with a blanket covering myself to prevent glares on the window, but so worth the excitement! I used a Nikon D850 with 14mm lens at F2.8, 15 second, and ISO 20,000.

Rosette Nebula

Copyright: Matthew Dieterich https://live.staticflickr.com/65535/495 ... dc3c_h.jpg

Pictured here is the Rosette Nebula near the constellation Orion. The image is a combination of 3 separate filters that pass sulfur, hydrogen alpha, and oxygen wavelengths. Shooting through these very narrow bandpass filters is awesome because one can image during the full Moon with minimal impact to the photos. These filters also help cut through light pollution if you image near a bright city! I captured this image from ObsTech in Chile with a PlaneWave Instruments CDK24 and L-600 mount. Total exposure time through each filters was 8 x 10 minutes. Hope you enjoy the view!

Centaurus A
www.mdieterichphoto.com
Copyright: Matt Dieterich I imaged the Centaurus A Galaxy from the pristine dark skies of Obstech in Chile. The galaxy is an estimated 10 to 16 million light years away. Amazing to think that the galaxy is also 60,000 light years across! So that means the light takes 60,000 years to travel from one end of the galaxy to the other end! Considering 1 light year is 5.8 trillion miles I can't even fathom that scale! Imaged in collaboration with Nick Dunckel and PlaneWave Instruments CDK24 with the L-600 mount. I used 10 x 5 minute exposures through LRGB filters.
