Dusty Perseus and Taurus,

please find my quite aggressive approach to dusty region between Taurus & Perseus. The picture was taken at the last day of August in southwestern Poland. It's a combination of 60x120s expositions taken with modded Nikon D610, Samyang 135 and aggresive processing for revealing the complexity of dust structures.
larger size available here: http://iro.net.pl/astrophoto/dusty-taur ... erseus.jpg


It's quite sentimental region of the sky for me as I used to live for about 16 years at Perseus Street walking to the school with colleagues from Orion Str. and Andromeda Str. :) [this is what happens if your city has Copernicus' district :D] I hope you like the picture.


Kind regards
:)

Eye of Creator - four narrowband channels Helix

The image is a blend of 0.55 HA_SNO + 0.1 HA_HNO + 0.35 HA_HSO. I know, not really scientific, but pretty.

Integration (203 hours of useable data in total captured during 40-50 sessions over several months across two winters):
HA = 194 x 900s + 157 x 1200s
OIII = 124 x 900s
NII = 88 x 900s
SII = 167 x 900s + 22 x 1200s

Data was acquired with a 105mm CFF on Mach1 and QSI 690 from our backyard in a coastal town 20deg South of the Equator.

The thin bows registered only about 1 photon per hour of exposure with my set-up, that's why a relatively long exposure was needed to allow for showing the fainter extensions.

Gum 85 in HA_RGB

In this image of a less familiar but interesting object, Ha was used for detail and RGB for colour.

Total integration is just over 52 hours, data was collected with a 105mm refractor from our backyard in a coastal town 20 deg South of the Equator.

Cygnus Loop Mosaic- 120 Hours of time across four months.

Image

Full Resolution and animated GIF of VISIBLE VS NARROWBAND: https://www.astrobin.com/full/yqajrh/D/

Full details:

Lots of work between two states and four months, but a worthwhile view into the heavens. I created a GIF to reveal the hydrogen and oxygen (black and white skeleton) present in the region; leftovers from an ancient supernova. 6 panel mosaic; 22hrs of integration per panel- 120hr project over four months. Shot both from my scope in a remote facility in Texas and in my driveway and local dark site in Tennessee. Time under clear skies is precious and I try to maximize it.

Images acquired in June, July, August, September and completed in October after finishing up the Oxygen channel. Framing mosaic wizard used to create a six panel mosaic. Acquired in Sequence
Generator Pro, calibrated in Pixinsight, and adjusted for levels in Photoshop; exported as a GIF in Photoshop.

Data captured on my dual system (currently split between two states)

- 2xWilliam Optics 132 w/ QHY 16200 CCD cameras; QHY MOAG w/5Lii
- AP Mach 1 GTO

Image integration:
40 x 180 L
40 x 180 R
40 x 180 G
40 x 180 B
40 x 600 Ha
40 x 600 O3

EARTHSHINE

It occurs when all sunlight is reflected away from Earth, and the Earth-facing side of the moon is almost invisible.
Sometimes the dark face of the moon captures the reflected glow of the earth and returns that light. The dark face of the moon has a faint glow, a ghostly version of a full moon. The phenomenon is called earth glow or cinematic light. It tends to be brighter between April and June, although it occurs at other times of the year.

A Bridge Not Too Far

47-hour-old crescent Moon is about to set behind Eastern pillar of Megyeri bridge. This bridge is the northernmost and youngest one of Budapest. Fun fact: it was opened on 30th September 2009 so the photo was taken on its 11th birthday. :)

"A magical ring of fire... our sun"
Total solar Eclipse
July 2, 2019
La Higuera town (La Serena )
IV Region, Chile

By: Luis Calle Rosasco (@luis_astrofoto)

Hi Guys !!...i'm gonna make you a direct question to all of you: ⁠

Is it worth taking a 4-hours flight to another country, driving 5 hours to the observation area in order to enjoy 2.5 minutes of total darkness and get some images about something that you will be probably living once in your life ??...In my opinion, It's worth every second !⁠

For that ocassion, i considered It was a great idea to try to do something different: capturing a solar eclipse in H-Alpha with a solar scope, instead of the classic Mylar filter / Baader film attached to a DSLR camera lens, getting more info about solar activity during partial/total phase.⁠

Here are the results...the stunning solar flames just a few seconds after finishing the total phase, were simply awesome, shocking, outstanding!⁠

Equipment:
- Coronado PST 40/400mm f10 H-alpha telescope
- ZWO ASI294MC camera
- Barlow 2x lens
- Skywatcher Star Adventurer
- Expo time: 2 secs (1 x 2 secs frame)
- Capturing/processing: Firecapture, Pixinsight, Adobe Lightroom

Ghost Nebula (SH2-136). KG Observatory, Julian CA.

Recently a few folks on Astrobin suggested I try the elusive Ghost Nebula (SH2-136). This is a challenging LRGB object with virtually no signal in Ha or OIII. Long integration in dark skies is very helpful.

My goal was to collect my normal 6 hours of L and 3 hours of each RGB channel (15 hours total) with FWHM on 15 minute subs <= 2".

During the 10-day dark window, the first 3 days were great and then it was cloudy for 5 days. After that, the night time air temperature dropped 20 degrees and the ground was still warm. That apparently was the perfect recipe for 3"+ FWHM seeing.

It steadied enough on 9/30 to collect another hour of L and to fill in some RGB.

Adam Block's excellent capture with his 32" at 9,157' was my reference...

http://www.caelumobservatory.com/gallery/sh2136.shtml

What you see here is 24" at 4,200' in 21.4 SQM skies. It was a long 10 days. I very much appreciated the requests and enjoyed the challenge.

Comments are very welcome!

"Spooky shapes seem to haunt this starry expanse, drifting through the night in the royal constellation Cepheus. Of course, the shapes are cosmic dust clouds faintly visible in dimly reflected starlight. Far from your own neighborhood on planet Earth, they lurk at the edge of the Cepheus Flare molecular cloud complex some 1,200 light-years away. Over 2 light-years across the ghostly nebula and relatively isolated Bok globule, also known as vdB 141 or Sh2-136, is near the center of the field. The core of the dark cloud on the right is collapsing and is likely a binary star system in the early stages of formation."

I love this image. It reminds me slightly of the APOD of October 2, which shows molecular clouds floating "serenely" against the backdrop of the energetic Carina Nebula.

Airplanes, satellites, Muon's, Worm's/ Gamma rays.... Normally we remove all the traces of cosmic radiation and human Engineering visible in the Sky. Radio-active particle traces and Gammy rays have to be removed also. It is kind of busy in the Sky these days as shown here in this stack of 223x300 second exposures made without fancy statistical cosmetic outlier removal.
