Pillars of Creation - Ha-SII-OIII-LRGB Backyard Version. KG Observatory, Julian CA.

Just an idea I had to do the Pillars of Creation in a more traditional way to help preserve the natural RGB with subtle Ha, SII and OIII highlights.

I was hoping to get 5-minute Ha subs significantly below 2" FWHM. That's primarily where the detail comes from. What you see here is 1.9" to 2.1". If things steady down over the next few days I'll upload a new revision. (-:

Some folks say the little "worms" on the right are more distant Pillars of Creation. I was happy to capture those little guys. (-:

SII = yellow highlight. OIII = blue highlight. Ha placed over the top as a hard light layer with no added color.

This is 2x drizzle with noise reduction only on SII and OIII. No noise reduction needed on Ha, L, R, G and B due to a very strong signal.

A very close conjunction between planet Venus and the Moon, both in the phase of thin crescent. A few minutes after, Venus was occulted by the Moon. Shot with a Canon EOS 6D and a Pentax 75 SDHF refractor from Oslo, Norway. One version straight from the camera and one with enhanced contrast.

Venus and Moon conjunction and occultation

Copyright: Stefano De Rosa Please find above three images (together with a collage of them) I took this morning, June 19, 2020, when crescent Moon and Venus put on a great show, first in the splendid twilight colors, then above the Church of Santa Maria della Neve in Pecetto Torinese (North-West of Italy) and finally with a broad daylight occultation.

The transit of the ISS one hour before the occultation of Venus by the Moon, June 19th from Parma, Italy

I was located exactly on the line calculated by Calsky (within 20m), actually I would have had to be 200m further South for a transit on Venus

North America, Pelican & unnamed bluish reflection nebula



One of the most popular summer's target, this area is mainly embbeded in reddish emission nebula; however, at bottom right of the image it is barely visible a bluish reflection nebula, surrounding a mag 7.3 star, SAO50102. You have to link to high resolution image to clearly see it.

I haven't been able to find an specific designation or catalog number for this reflection nebula. It isn't visible in most of amateur astrophotos, I think because H-alpha filters are widely used for this zone and they kill faint reflection nebulas.

Fantastic, Javier! To me, the diehard lover of blue things, this is a great find indeed!

Tatras Red Sprites



Picture shot at date 12.6.2020, 22:56 UTC in the Jeseníky Mountains - Czech Republic and captures the Red Sprites over Tatras Mountain in Slovakia.
The distance of the observed phenomenon is about 250km.
Technique: Sony A7S – full modified and lens Sigma 105mm/f1.4. Settings: ISO 2500, time 2,5 sec, f/1.4. Postprocessing was performed by a Prof. RNDr. Miloslav Druckmüller, CSc.
From this storm I caught more than 30 Red Sprites, here is link to my gallery on Facebook: https://www.facebook.com/pg/ScerbaDanie ... tn__=-UC-R

At this time of year, the Southern Cross is high in the sky as the evening starts, almost overhead for those of us living at temperate southern latitudes.

The Australasian Dark Sky Alliance are also running a world record attempt to measure light pollution by counting the stars that people can see in the Southern Cross on the day of the winter solstice:

The Cygnus Loop

Located near the "Swan's Wings" in the constellation Cygnus, the Cygnus Loop is a supernova remnant - left behind long after a star exploded approximately 5000-10000 years ago. The region is so large that it contains individually named objects such as NGC 6992 (the Eastern Veil Nebula) on the left side and both NBG 6960 (the Western Veil Nebula) and Pickering's Triangle on the right side. The swirling gas and dust continues to expand to this day and it is theorized that the supernova that created the nebulae could have been seen from Earth! This image is a 4 panel mosaic in H-Alpha and OIII taken from my backyard just outside of Houston, TX.

A stacked composite image of the Partial Solar Eclipse seen from Bangalore, Karnataka, India on June 21, 2020. The image you see shows the movement of the Moon, right from the start of the eclipse at around 10:12 AM local time, traversing the Sun until the end of the eclipse at about 1:31 PM local time. The maximum eclipse occurred at around 11:47 AM local time. The monsoon is here but luckily, I was able to see and photograph the eclipse for about 3.5 hrs.

Details :
Nikon D7000 + Nikkor 200-500 lens + DIY Baader Solar Filter
Location : Bangalore, India
Number of images stacked : 30

M91 (NGC 4548) is a barred spiral galaxy in the constellation Coma Berenices. It is one of the faintest Messier objects at approximately magnitude 11. M91 is about 63 million light-years away and has an apparent size of 5.4 x 4.3 arc minutes. Observations of Cepheid variable stars by the Hubble Space Telescope confirmed that M91 is a member of the Virgo Cluster [https://iopscience.iop.org/article/10.1 ... .text.html]. M91 is classified as “anemic” for its relative lack of star forming regions and gas, possibly resulting from ram pressure stripping as it passes through the dense galaxy cluster [http://adsabs.harvard.edu/full/1999A%26A...349..411V].

Hope you enjoy the image!
