The Colors of the Pelican

Copyright: Bogdan Borz

Living in a Bortle 8 zone, I am really glad that the summer nebulae are up in the sky and the narrowband season can begin. I shot the Pelican Nebula from my backyard, with the Altair Astro 115mm refractor and the ASI1600MM, using 3nm narrowband filters for a total of 17.8h.

Best regards.

Every 19 months, Venus passes between the Sun and the Earth. And, once out of 5 (that is, every 8 years), Venus looks particularly close to the Sun in the sky (exceptionally, it can even transit the Sun, which happened in 2012 and will happen again in 2117).

This image was taken this morning while Venus was only 2,4° from the Sun. As it is backlighted, all we can see is its thin atmosphere of CO2 that scatters light and gives it this shape of complete ring.

Chambord Castle (France) with the Milky Way, Jupiter and Saturn

A beautiful night spent around the castle, in mid-May 2020.

There was a lot of humidity, with the canal and the forest surrounding the building. It can be seen on the sky, the yellowish horizon and the heart of the Milky Way yellow instead of being white.

Jupiter and Saturn are visible just above the castle, very bright.

BEAUTIFUL SPACE CLOUDS
Copyright: Alan C Tough

The summer months are the best time for seeing the high-altitude, electric-blue clouds known as Noctilucent Clouds (NLC). NLC form on the edge of space when water vapour condenses and freezes onto small meteoric dust particles. These eerie and extremely tenuous clouds can only be seen under the right lighting conditions: i.e. when the Sun is between 6 and 16 degrees below the horizon and the temperature in the Mesosphere is low enough. Therefore, in the northern hemisphere, the best time to view this phenomenon is from the last week in May to the first week in August (between the hours of 11 p.m. and 3 a.m.).

I captured this beautiful early-season display, at 00:34 UT on 2020 June 1, from a field near my house in Elgin, Moray, Scotland.

Crescent Venus and the Ring!


You see these irregularities in the Venusian atmosphere ring arc?
I had the idea of using a Herschel Prism from Baader Planetarium and a RG-610 filter. It worked perfectly for the images of the inferior conjunction.
I also used the refractor (AP Traveler) without a prism. The irregularities can be seen in all image series.

Snake Nebula ---THE BLACK SNAKE IN THE SIDERAL SPACE

BEST DETAILS AND QUALITY:
https://www.astrobin.com/full/u5y66k/0/

Dark nebulae are a show apart, some visible with the naked eye in places with low light pollution, these regions are a type of interstellar cloud so dense that it obscures the starlight in the background.
Dark clouds appear like this due to micrometric dust particles, coated with carbon monoxide and frozen nitrogen, which effectively blocks the passage of light at visible wavelengths.

THESE DUST MOLECULAR CLOUDS PROBABLY CONTAIN SUFFICIENT RAW MATERIALS TO FORM HUNDREDS OF THOUSANDS OF STARS

Here we can see:
1) the serpent nebula in the center (B72),
2) Lower right corner (B261)
3) Three small nebulae from top to bottom on the left side of the healthy snake (B68, B69, B70)
4) In the lower left corner is B74, in the shape of a heart.

'LoTr 5 and its galactic neighbors, NGC 4725 & NGC 4747'

Copyright: Sabine Gloaguen
https://en.sabinegloaguen.com

At the top left of the image, LoTr 5 is a bipolar planetary nebula with two round lobes giving it a peanut shape.
Near the middle of the image, the galaxy NGC 4747 (or Arp 159 in the catalog of peculiar galaxies) has long tidal tails following strong gravitational interactions.
Its neighbor is the galaxy NGC 4725. Its yellowish center is formed by old and cool stars, while hot young stars colored in blue its outskirts. Note the special presence of a single main spiral arm.
On the far right, NGC 4712 ends this diagonal of objects.

It's great to see a female deep-sky photographer! And I really like the picture. I particularly like the color contrast between the planetary nebula and the galaxies. That blue-green color of LoTr 5 seems just right for an OIII-rich planetary. I like the tidally distorted galaxy NGC 4747, too.

Interestingly the center of the planetary seems yellowish. Any ideas as to why that is so?

Thank you so much for your nice comment Ann. Indeed I would be happy if more pictures were submitted by women, I hope they will follow our way!

Indeed I really like this field with so peculiar objects. Regarding the center of the PN, I read that its center is a binary system of stars, the color is as a result.
