Simeis 57, also known as the Propeller Nebula, is a captivating celestial object located in the constellation Cygnus.
It is part of the vast Cygnus X molecular cloud, situated approximately 4,600 light-years away from our Solar System.
This intriguing nebula resembles a spinning propeller, with opposing arcs of reddish light extending symmetrically from a common center.
Its unusual appearance has earned it nicknames like the Garden Sprinkler Nebula.
While challenging to observe visually due to its red emissions, astrophotographers have captured its beauty through long integration times.
With an impressive integration time of 96 hours at f3.3, the propeller shape within the nebula appears more diffuse compared to the surrounding regions. However, this extended deep capture reveals new intricate details around this renowned celestial feature.

Before concluding its mission on 15 September 2017, Cassini captured one last view of a lone ‘propeller’ feature, one of many such small-scale dynamical features created by small moonlets embedded in the rings as they attempt, unsuccessfully, to open gaps in the ring material.
The image was taken on 13 September 2017 with the wide-angle camera at a distance of 676 000 km from Saturn. Image scale 3.7 km. It is among the last images Cassini sent back to Earth.
The Cassini–Huygens mission is a cooperative project of NASA, ESA and the Italian Space Agency.

Any comments welcome :)
Tulip.
I think I must be addicted to this viewpoint for photographing tulips, and tulips themselves. My only excuse is that there is such variety in the flowers that each one is different and interesting :)
I took this at a garden I was visiting on an Open Garden day where I was playing with my 50mm lens… and the flowers. I rather liked the spiral and the stickiness of the stigma - it reminded me of a propeller, hence the title.
This is for 7 Days with Flickr Wednesday’s Macro theme.
Thank you for taking time to look. I really hope you enjoy the image :) Happy 7DWF!

Processed in DXO Photolab to emphasise the colour and detail in the centre.
Touched up in Affinity Photo to remove some blemishes; soft white vignette, long crop to give some context (and I like long crops!).]
Ever thought riding a bicycle is way too much environment friendliy and silent? Then this is for you!
