DESCRIPTION: Cloudy nights = more time for learning post processing skills… I reprocessed older data from June, 2020. The same photo were posted on June 2020. I am not so satisfied with stars shape and quality, maybe it caused by optics. I would very appreciate your comments or tips.

OBJECT: NGC 6888, Crescent Nebula, Constellation Cygnus (Swan), apparent magnitude 7,4, apparent dimension 18 x 12 arcmin, FOV 3,6 x 2,5 arcdeg, cropped 1,25 x.

GEAR: Nikon Z7 Kolari Full Spectrum + Nikkor 500/5,6 PF, Rollei Astroklar Light pollution filter, tracking mount iOptron CEM60EC - 3 star alignment, no auto guiding, dew heater.

ACQUISITION: June 24, 2020, Struz, CZ, Exposure 240s, f 5,6, ISO 400, Light 15x, Dark 5x, Bias 5x, Flat 10x. Total exposure time 60 min during Astronomical twilight.

STACKING AND POST PROCESSING: AstroPixelProcessor, Pixinsight, Adobe Photoshop CC 2021.

First Orion and first interaction with Pixinsight, this programme is a whole new level!

Shooting in -12 degreec C didn't turn out to be easy, though clear sky and long nights are a big opportunity for good shots.

This is a 17 image composite of the total solar eclipse taken from Madras, Oregon. All exposures used were taken in short succession during totality and the diamond ring phase.

In addition to the impressive corona and some prominences, the structure of the moon is visible as well. This is possible due to earthshine: reflected sunlight from earth is illuminating the dark side of the moon.

Also visible are two stars: Bright Regulus is obvious in the lower left of the frame and 5th magnitude Nu Leonis is dimly visible on the upper right of the sun.

The total lunar eclipse of November 8, 2022 was a wonderful sight to behold! High clouds added a soft diffusion to the reddish moon, giving the scene an etherial quality.

During my astrophotography trip to the Canary Islands the Tajinaste rojo were in full bloom.

Standing between these strange looking flowers in the barren volcanic landscape of the Las Cañadas caldera and seeing the starfilled sky unfold above me, evoked a feeling of being in a completely alien world. One of the spots that almost gave me goosebumps was this sloping hill, where the terrain nicely matches the angle of the rising Milky Way.

As a Swiss national I found it interesting to learn that the scientific name of the Tajinaste (Echium wildpretii), honours the 19th century Swiss botanist Hermann Josef Wildpret, who was head gardener of the famous botanical garden Jardin de Aclimatación de la Orotava (also called Botánico for short) near Puerto de la Cruz on Tenerife.

My last post from the Teide National Park on Tenerife showed the stunning Tajinaste Rojo. While they are the most obvious endemic flowers on Tenerife, they are not the only ones. The Rosalillo de Cumbre (Pterocephalus lasiospermus) pictured here is another example.

This beautiful shrub, coloring an otherwise barren landscape, immediately caught my eye and I was glad to find that it nicely aligned with the vertical Milky Way.

September is a special month for astrophotography in the mid northern lattitudes. The memories of the warm summer nights are still fresh and we have the last chance to capture the Dark Horse and the Milky Way core for a few hours in the evening. Winter is approaching fast though and the rise of Orion, the hunter, in the morning hours is an unmistakable sign for this. Between the MW core and Orion, Cygnus is riding high in the sky, giving even more options for nightscape compositions.

During a perfect night out with Benjamin Barakat, we had the chance to shoot this little chapel from different angles, taking advantage of all possible astronomical alignments. My favorite capture is this one with Orion, Barnards Loop, Rosette Nebula, Meissas nebulosity, the Hayades, the Pleiades, California Nebula and Mars shining brightly on the upper right.
