Van den Bergh 14 & 15 along with SH2-202 in HaLRGB. This is a 2-panel mosaic from data I finished capturing a few months ago but hadn't had the time to sit down and process until now. I am properly proud of this image, more so than any of the others I have made since going remote. The stark contrast of the blue reflection nebula and the hydrogen alpha emission from the Sharpless cloud juxtaposed next to each other make this an extremely dynamic region.

I have not seen that many images of these objects in particular on Astrobin and thus wanted to shoot it in the hopes of inspiring others to make even better images of it in the future.

-------------------------------------------------------------

Processing:

For each pair of masters per filter:

- DynamicCrop

- MureDenoise

- DynamicBackgroundExtraction

- ImageSolver script with distortion correction enabled to platesolve each panel

- MosaicByCoordinates script to create mosaic master templates

- PhotometricMosaic script to stitch panels into masters for each filter

RGB Processing (apply to each master):

- DynamicCrop to remove mosaic edges

- DynamicBackgroundExtraction

- StarAlign G/B/Ha to Red

- Combine RGB linear masters into color linear image with ChannelCombination

- DynamicBackgroundExtraction

- SpectrophotometricColorCalibration

- StarXterminator to remove stars for processing and save star_mask

- NoiseXterminator x2 for noise reduction

- BackgroundNeutralization with preview for color correction

- NoiseXterminator at 0.25 for further NR

- HistogramTransformation for initial stretch and then further green channel tweak

Create Continuum-Subtracted Image for non-linear Ha Addition:

- StarAlign Ha master to Red

- PixelMath to assign Red and Ha to HRR as RGB respectively

- BackgroundNeutralization using background preview and ColorCalibration to isolate Ha signal

- StarXterminator to remove stars from linear image

Luminance Processing:

- DynamicCrop

- DynamicBackgroundExtraction

- StarAlign to Red

- StarXterminator to remove and extract stars - save stars_only image

- GeneralizedHyperbolicStretch for intial stretch

- HistogramTransformation x3 for further stretch

- CurvesTransformation for contrast

- UnsharpMask with luminance mask applied to sharpen reflection tendrils

- ACDNR with luminance mask applied for slight noise reduction

Combine Luminance and RGB:

- LRGBCombination with chrominance NR enabled

- Extract luminance mask and CurvesTransformation to super stretch

- Apply luminance mask and invert mask

- MultiscaleMedianTransform with inverted lum mask for chrominance noise reduction

Add Ha to LRGB:

- NoiseXterminator on linear Ha image for noise reduction

- HistogramTransformation x3 to stretch

- CurvesTransformation for extreme contrast curve to suppress background and isolate Ha signal

- PixelMath to add Ha to LRGB

- ColorSaturation to saturate blue reflection nebulosity

Further Processing:

- CurvesTransformation for slight contrast adjustment

- HistogramTransformation x3 on RGB stars to stretch to non-linear

- Invert -> SCNR green -> invert to remove magenta from stars

- SCNR green on stars

- CurvesTransformation to saturate and bring up blue point for stars

- HistogramTransformation x2 on Luminance stars to match size of RGB stars

- LRGBCombination to combine Luminance and RGB stars with saturation at 0.35

- ColorSaturation to saturate blue stars

- PixelMath with re-linearization technique to combine stars with starless nebulosity

- NoiseXterminator for final noise reduction

- SCNR green to remove slight green tint

- MorphologicalTransformation with luminance star_mask applied for slight noise reduction

- CurvesTransformation for final green reduction/'c' curve adjustment, and contrast boost

- DynamicCrop to crop edges

- Save and export

On this week's episode of find the train: the STMA Plummer Turn returns over Benewah Lake on its eastbound journey back to St. Maries.

I got to wander along Burrard Street yesterday while my parent's furniture was being removed, couldn't watch, too painful. Anyways, it was hot out, but thankfully there was a breeze and I had taken a pill for my lurking migraine so I just lollygagged along, taking in the sights and spotted the Vancouver Telescope Centre on the corner of 10th and Burrard ?? when did that appear ?

Eventually I returned to the apartment, was too hot and tired to wander anymore, and I got to witness the last of the furniture being fitted into the truck like puzzle pieces by a very nice young guy named Daniel, a university student with a shitty summer job. Now all we have to do is gather up the remaining bits and bobs and close the door on another chapter of my life, but, you know what? I'm doing all right.

On top of the world....always a favorite spot to visit when we're in the Tetons; great for sunrise or sunset with views of the Teton range in one direction and the Teton valley in the other. Enjoyed the company of a blue grouse on this particular evening as well as an interesting storm front brewing in the distance. Mike was scoping while I was photographing, one of his favorite things to do when we're out west; and I couldn't resist a shot of my favorite model :-) He told me he's going to start charging a modeling fee....LOL!!!!

Have a great Thursday, and as always, thanks for visiting and commenting!!!!

Appreciation to the Jackhammer's designer =]

I thought t this scope was very interesting.

Puting up the code for the scope in a few.

A fun experiment with my old Canon 700D which I haven't used for astro for a few years. I enabled LENR and shot under 3 hours of data (82 x 120s + 59 x 10s) but these objects are so bright and fantastic the resulting image is still quite pleasing. I was impressed how effectively LENR blitzed the noise with the camera sensor around 30C. The camera was on a WO Zenithstar 103 scope, no filters were used. Image acquisition was managed via SGP and PHD2, all post-processing was done in PixInsight.

A ski mountaineer checking out the many options for a perfect day of #skiing at #Tuckermans from Hojo's. This guy proceeded to head up to the Hillman's/Dodge's area and I headed up into the bowl where I had the place to myself for 2 hours! The first run was still icy but the next 5 were amazing!

I'm on facebook now!

Alright this is the second beautiful scope I made for Sweetwater, I hope you like it!

Here's the full code: www.mediafire.com/?w9giahejh65br3h

The size is deduced to 1.9MB, so there's 600kb gone =]

Thanks again, Jake!

Please credit me and the Sweetwater team if you've used this scope. There's no need to take off the Sweetwater logos anymore. Just make sure to credit us.

Thanks to The Wezzy for the scope mounts!

Feel free to comment.

One shot I got from tonight, after an incredibly frustrating day trying to scope out a spot. Tried to do a composition shot during the blue hour, but I was off by about an inch from where the fireworks went off. Grrrr

Every get the feeling your looking the wrong way?

The Xeno Hovercar Company, formed in the late 2030's as a conglomerate of several small hovercar startups was the first company to successfully sell hovercars in mass. Small, quiet turbines made them usable within cities, and their sleek design made them irresistible to consumers. They were sold for exorbitant prices, and very soon after release three words were commonly heard across dealerships- "Bill Me Later"

As the otter was eating the small fish it just caught and the mother Mallard was escaping with her two ducklings (two previous posts), this eagle flew overhead and carefully scoped out the events transpiring below before continuing on it's way.
