Eiffel Tower of the sun. it's quite interesting seeing solar activity especially when it reminds us of things on our home spaceship. what's mind boggling is this eiffel tower of fire so so big it could easily engulf our tiny planet.

Hi everyone!

This picture of the Rosettte Nebula was taken in Portugal on 27-01-2022. A cold night where I shot 3h10 minutes of data.
I used an Astro STC Dual Narrowband filter in order to capture more details on the Ha and OIII wave lenght.
This huge and beautiful molecular cloud lies about 5.000 light years away from us, and can be seen in the sky on the constellation Monoceros.

Lunar volcanic activity: Hyginus region
Hyginus, Triesnecker, and Ariadaeus by Tom Glenn, on Flickr

Full size image

Hyginus crater and its associated rille system is located near the center of this image taken along the sunset terminator of the waning Moon. Hyginus is unique among lunar craters because it is not the result of an impact event, but rather by lunar volcanism. The crater itself is thought to be a caldera, and the rille was formed by lava flows that also experienced collapse. The prominent rilles Triesnecker and Ariadaeus are also visible in the image, to the south and east of Hyginus, respectively. Significant regions of dark pyroclastic deposits are visible throughout the region, notably to the north of Hyginus in Mare Vaporum, and to the west (left side) of the image. The very smallest craters visible in the full sized image are just under 1km diameter.

Messier 51 - The Whirlpool Galaxy in the constellation Canes Venatici

The Whirlpool Galaxy, also known as Messier 51 is a grand design spiral galaxy located about 30 million light years away. It appears face-on when seen from Earth and was named the Whirlpool galaxy because of its swirling spiral structure. These spiral arms are star-formation factories, compressing hydrogen gas and creating clusters of new stars.

Messier 51 is gravitationally interacting with a smaller dwarf galaxy, NGC 5195.

Total exposure: 20 hours
Location: Georgetown Texas

39-Panel Solar Mosaic
https://live.staticflickr.com/65535/518 ... 3cba_k.jpg

This is a high resolution, 39 panel, solar mosaic captured on February 1, 2022.

A total of 78,000 individual frames were captured and 10% of the best were selected. After stacking, 39 panels were hand aligned over the course of 6 hours. Each panel was calibrated in exposure to ensure that every one matched in brightness. Each panel was blended together using "Auto-Blend" in photoshop, then an inverted stretch was performed to enhance chromosphere features and to add contrast. Afterward, deconvolution and sharpening took place, the image was converted to RGB color working space and colors were synthetically added. The image was exported as JPG.

Featured in the image are sunspots: AR2940, AR2938, AR2936, AR2939, and AR2934. Additionally seen are solar prominences found on the solar edges.

Integration:

10% best frames selected and stacked in AutoStakkert

Cloud iridescence or irisation is a colorful optical phenomenon that occurs in a cloud and appears in the general proximity of the Sun or Moon. The colors resemble those seen in soap bubbles and oil on a water surface.
The colors are usually pastel, but can be very vivid or mingled together, sometimes similar to mother-of-pearl.

First light at night?

I don't know if that's fair but this is the first light with the Lunt LS100MT in night mode. Quite a simple switch from day to night and I was up and ready to image in minutes. Finding the moon without being properly aligned without a guide scope during the day proved to be another difficult task though. Attached is a 6 or 7 panel high resolution mosaic, I wanted a little more flair to it so I added some stars from my previous rosette nebula session. I hope you enjoy it!

"Two Galaxies"

Two worlds comming up together. In the background you can see slowly setting Scutum, Ophiuchus and Aquila regions of Milky Way. During this time our closest large neighbour, The Andromeda Galaxy, was rising on the opposite side of the sky. I used a mirror to capture it's reflection. Reflection is 100% real and I didn't interfere with it.

The Fishhead Nebula in Hubble Palette 

The Fishhead Nebula is cataloged as IC 1795 and NGC 896 and islocated right next to the Heart Nebula, in the constellation of Cassiopeia.
I thought of photographing it in a narrow band aiming to compose a Hubble Palette that would enhance the abundance of ionized gases present in this highly star-forming area of the cosmos.
Here, about 7,500 light-years from our planet, tall columns and clouds of gas and dust generate new stars in a constantly renewing cycle of birth and death.
The composition in Hubble Palette foresees to assemble three monochromatic channels dedicated to three chemical elements abundant in thiskind of emission nebulae: ionized sulfur SII, ionized oxygen OIII and ionizedhydrogen H-Alpha. By assembling the channels with a sequence SII:Ha:OIII, a combination of colors is obtained that generates a lot of depth and highlights the different distribution of the elements. 

Integration:
Ha 3nm 36x600’’
OIII 3.5nm 25x600’’
SII 3.5nm 49x600’’
Total integration: 18.3h

This is a 3 panel mosaic of the Rosette nebula (NGC 2244).

I shot this from my backyard with the following equipment:

Total integration time: 46 hours 40 minutes.

Happy Saint Valentine's day to everyone!

I captured all the stars in one night with exactly the same exposure time and focal length to really compare them. (10x5s exposure on each color layer RVB)

I just love it! Thank you, thank you, thank you! Thank you so much for really comparing the visual color of stars, and, not least, really showing us that bluish stars truly are different shades of blue!
