The January 2019 Challenge is now open. The target is Barnard 33, Horsehead Nebula. To reduce the number of stickies, please submit your entry to this thread.

 

The Rules will remain pretty simple:

  •       Your Equipment
  •       Your Data, Captured This Season
  •       Your Processing
  •       One Entry Per Member

To increase participation over such a diverse group, the winner will be selected by random drawing. Please feel free to start a thread requesting guidance on your entry prior to submitting it, the whole purpose of this challenge is to learn and compare on a common target. Entries must be submitted by midnight eastern time on January 31, and I will try to announce the winner early in February. Note: If I am late announcing, gently nudge one of the moderators in a private note, it helps wink.gif .

 

Please display an image in your post, not just a link!!

 

I hope everyone has fun with this one, and with that,

 

Let The Games Begin

My version of the Horsehead Nebula:

 

Equipment, AVX mount autoguided with PHD2 and touptek cam, SharpStar 65EDQ quadruplet refractor, Canon T2i LP2 removed.

Data: 36 x 300s ISO1600, using in camera LENR due to the high temp, Astro Photography Tools as my adquisition software, captured Nov 30 2018

Still learning how to use Astro Pixel Processor, increased contrast with photoshop.

Thanks Goofy for choosing this beautiful object, which I had imaged on 12/13/18 and 12/15/18.   This picture comes from an ASI183MM Pro Camera and a Stellarvue 70mm refractor at 330mm focal length.  There were 48 4 minute subs of H-alpha used at a 30% blend with 70% luminance, and a 50/50 blend in the red channel.  LRGB were 30 second subs with 53 min of L, 17 min of red,  31 min of green, and 31 minutes of blue.  The camera was set at 160 gain, at -30C.  The pictures, with calibration files were  processed in DSS, StarTools, and Gimp.  The mount used was a CEM-60, auto-guided.  Had fun trying a lot of different versions of the object, but settled on a dark sky, colorful version.

With a break in the clouds in Copenhagen, used a QHY 183M with 7x300s in RGB to capture this with a 102mm refractor at f/5.6 ish.

 

Integrated and processed with PixInsight and finished off with Photoshop CC 2019.

I took this one the night of December 17th, 30x 180s at ISO 1600 on the astro modded Pentax K5, TMB92, ATFF2, ZEQ25, and MGEN II for guiding. Then stacked in DSS and processing in Photoshop CS6.

This is 4.5 hours of data over two nights, 1.5 hours of 300s subs at ISO 400 and 3 hours of 300s subs at ISO 800. Imaged using my WO Star 71, HEQ5 and unmodded 550D with CLS filter, guided using a 290 Mini and PhD2. Integrated and processed in PixInsight.

 

I'm slowly working my way through "Inside PixInsight" as well as the Light Vortex tutorials. I think I went too heavy handed with noise reduction but it's 30C-35C during the day and not much cooler during the night, BYEOS has recorded the sub temps around 39C-44C! I didn't like the colour image for whatever reason, no fault of the CLS filter, PI does a pretty good job of balancing the colour, I just felt it was off. So I extracted the luminance.

My attempt at getting close to just the horsehead in H-alpha.

 

Taken from Tokyo with EdgeHD800 with 0.7x reducer on October 22nd 2018 (I hope that qualifies as the same season!). Vixen AXJ mount, and Astrodon 3nm HA filter, 15 x 480s exposures with ASI1600MM-C.

The Horsehead Nebula (also known as Barnard 33) is a dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because its resemblance to a horse's head.

1/5/19: 50X RED
1/5/19: 50X GREEN
1/5/19: 50X BLUE

 

Data Used (Integration time per filter & exposure time after stacking rejection):

HA 10MIN: 6HOURS 40MIN INTEGRATION
HA 1MIN: 51MIN INTEGRATION
OIII 10MIN: 1HOUR 10MIN INTEGRATION
OIII 1MIN: 27MIN INTEGRATION
SII 10MIN: 6HOURS 40MIN INTEGRATION
SII 1MIN: 51MIN INTEGRATION
RED 1MIN: 1HOUR 37MIN INTEGRATION
GREEN 1MIN: 53MIN INTEGRATION
BLUE 1MIN: 51MIN INTEGRATION

 

TOTAL INTEGRATION: 1200 Minutes / 20 Hours

 

Processing:
Data for each filter/exposure time was initially calibrated and 2X drizzled through Deep Sky Stacker.
Final stacks were registered and further processed in Pixinsight.
Super luminance was generated from stacks in Pixinsight.
Stars were removed from narrowband stacks to create tone maps.
Tone maps were exported from Pixinsight as 16-bit TIF and cleaned up in Photoshop.
Fighting strong halos from filter reflections, bright stars were blended over the halos; i.e. stars from Red replaced halos in HA, etc.
Tone maps brought back into pixinsight.
RGB image created in Pixinsight and stretched to be non-linear.
Tone maps were mixed with the RGB image through pixinsight's NBRGBCombination Script.
Curves transformation was used to further adjust colors.
Result was brought back to Photoshop for further noise reduction and color adjustments using the Camera Raw Filter.

Full size finished image is 6743px wide x 8602px tall at 72 dpi.

Posted image has been resized to 803px wide x 1024px tall at 72 dpi.
