The Double Cluster (comprising NGC 869 and NGC 884) is a beautiful pairing in the constellation in Perseus, located only a few hundred light years apart. The clusters have a combined visual magnitude of 3.7 and 3.8 and are visible to the naked eye as a fuzzy patch between Perseus and Cassiopeia.

Bonus points for spotting the small fuzz of a galaxy in the field

Great picture, coatesg!

Is the galaxy the small gray diffuse smear at far right?

Yes, well spotted - it's PGC168300 glowing at mag(B) 16.2. The whole area is quite low on the number of catalogued background galaxies - maybe not surprising as we're viewing through the disc of the Milky Way.

Here is my version of M42 in Narrowband. I have many versions of the processing trying to get the color the way I wanted it and learning new processes in PixInsight and trying those. I think it turned out rather well. I have pretty dark skies except in the south where all the pretty nebulae reside, it is washed out due to living next to an international airport. I hope you enjoy!

Bicolor image of the Jellyfish Nebula in Ha and SII

The Jellyfish Nebula found in the constellation Gemini, also designated IC 443, is a large supernova remnant. The emission of the nebula is due to the excitation of hydrogen atoms as the rapidly expanding shell collides with the surrounding molecular gas. The bicolor mage taken with a Takahashi CCA-250 f/5 astrograph and QSI683wsg CCD camera (Astrodon 5nm H-alpha & 5nm SII filter) on a Paramount ME in Mayhill, NM on the nights of the 23, 24 January 2018 and 7, 8 Feb 2019. Total of 15 hr 20 min exposure (Ha 21 x 1200 sec lights @ -20 degrees C; SII 25 x 1200 sec lights @ -20 degrees C; 24 darks; 128 bias; 128 flats). Processed in PixInsight 1.8.8 Ripley (x 64).

Tell me, though. In the caption you wrote the following:

The overview image shows the constellation of Cygnus and shows where the remnant is found.

Where is the overview image? I can't find it.

Ann

Thanks so much. The overview is in the bottom, but it is really, really small. This is better I think

This image shows the extended nebulosity around IC59/IC63. This nebulosity is very rarely found on imagery, and as far as I know only a handful of images showing this nebulosity can be found, where most of them only show a very weak impression of the nebulosity. With this image I hope to challenge people to image this beautiful region and maybe even bring out more details. It's really worth it!

The image was processed with astropixelprocessor and after that the starnet++ script in pixinsight was used to separate the stars from the nebulosity. Using Niktools the nebulosity was sharpened and stretched to show more detail in the final image.

North America and Pelican Nebulas
Copyright: Drew Evans

My first processed image off the 11" RASA. Amazed at what data can be collected in under an hour of imaging with this OTA.

The North America Nebula (at left) is a large emission nebula located in the vicinity of Deneb (top right), the brightest star in Cygnus. The nebula is famous for its shape, which bears a striking resemblance to that of the North America continent. It lies at an approximate distance of 1,600 light years from Earth. It is listed as NGC 7000 in the New General Catalogue. The North America Nebula is part of the same glorious H II region as its smaller neighbor, the Pelican Nebula (at right, IC 5070).

Description: we are in the asparanus sea area located in Syracuse, the sea is really rough, in this photo I caught a star trail pointing towards the North Star.

Equipment: sony a7iii, mc 11, canon 16 35 f4

We need to look more to the sky!


It caught my attention this photo by some points:

1) Fall of a meteor at the bottom of the photo
2) Capture andromeda over the larger screen, with a cloud high above it showing andromeda during photo enlargement. Detail, this cloud took too long to get out.
3) That peace and feeling of freedom that astrophotography causes.

This an image of Red Sprites and the milky-way. The image was captured from my front yard in Hereford, AZ. The image faces the Coronado National Monument in the Huachuca Mountains.
The thunderstorm occurred on August 31, 2019. I was taking a time lapse of the Storm and milky-way using an astro modified Canon 6D and a Tamron 15-30mm lens @f2.8 and15mm.
Individual stills were obtained using a 13 second exposure time at ASA 1600. This was my first attempt to capture a thunderstorm using time lapse. I think had some beginners luck.

G65.3+5.7 Ha_OIII- bicolor 2019 starnet-v2 location.jpg

Thank you! Very interesting! I had no idea that this remnant was so large. In fact, I had no idea it existed. The Veil Nebula sticks out like a sore thumb, but I have never noticed this one. It must be an old supernova remnant to be so large and faint. Surely it can't just be comparatively nearby, so that it is "diluted" compared with the background?

Thanks again!

The Double Cluster by Nico Carver, on Flickr

I have been experimenting with capturing broadband data using a DSLR and narrowband data with a cooled mono camera at the same time on the same field. I then register all the photos to a single reference, remove the stars from the narrowband data (h-alpha in this case), and overlay the DSLR image on top. This image is my first result. It shows the familiar Double Cluster with the less familiar clouds of Hydrogen (HII regions) only visible through deep exposure with a narrowband filter.

Clear skies, Nico
