Some nice colors in the sky If you’re north enough. Sadly I doubt this will be as strong as the aurora back in May, but maybe one day well get them down in Atlanta again

Oh no! Where will I go to see OF spam bots now???

Bye, Bob :-(

Finally done with classes and I got some time to at least star processing my pics. Gonna be a while before I figure out all the HDR stuff, so here's a pic of the prominences about 10 seconds before C3. It was absolutely nutty seeing them naked eye during the eclipse, and visually through my other telescope. Captured on April 8th, 2024 from Sikeston, MO.

You'll have to install AltStore (or Sideloady) on your computer + phone to resign the app each week (this can happen automatically if they're on the same wifi network). You can make your own personal API key at https://old.reddit.com/prefs/apps/ (It's limited to 100 requests per 10 mins, which you wont run into browsing by yourself). Also as long as you moderate a subreddit (I think even if it's just an empty one you make), NSFW content wont be blocked on the API.

Also while you're sideloading, I'd highly recommend uYouPlus for a better youtube app

Well I guess that’s one way to be a smart-ass

Astrophotography. Hell, just photography in general.

Refreshing the ublock caches work most of the time however if it doesn’t, clicking the share button and then ‘embed’ just brings up a regular non-blocked video player

This is a photo from a lunar transit of the space station a few years ago. I had another telescope setup to take a video of the pass, and here's a composite of the frames it took (the whole thing lasted less than a second).

I really enjoy the scale of this image, with the ISS being 540km away, and the moon some 380,000km in the background. more detailed info on the ISS Transit ISS transit can be found here courtesy of transit-finder. Captured on the morning of June 24, 2019 about 30 minutes after sunrise.

Equipment:

• Meade ETX125-EC

• AW 71" Camera Tripod

• Canon Rebel T3i (astro-modified)

• Meade #64 adapter

Acquisition:

• 1/800" at ISO 800 single exposure

Capture:

• I just held down the shutter button a second before the ISS pass occurred, and got 3 frames containing the ISS

Processing:

• AutoColor and Levels adjustments in Photoshop

• MLT noise reduction and annotation in PixInsight

They actually just got rid of the stars, now you just tip people

This is one of my longer projects, with 84 hours of long exposure time over 2 seasons going into this photo. Sh2-224 is an extremely faint nebula, and this is what a single 10 minute long exposure (through a Ha narrowband filter) of it looks like. I ended up getting ~83 hours of narrowband exposures like this, plus about an hour of RGB images for the stars. Because it's so faint, if the moon was up at all I did not shoot it, which cut the number of clear nights I could reasonably image it in half. The nebula itself is false color (although the HOO palette I used is fairly close to natural color), the stars were taken with RGB filters and are true color. With this project I finally managed to learn how to do some starless processing techniques for combining the stars+nebula

Captured over 27 nights between February 2021 and April 2022, from my Bortle 6 driveway

Capture Software:

• Captured using N.I.N.A. and PHD2 for guiding and dithering.

PixInsight Processing:

• BatchPreProcessing

• SubframeSelector

• StarAlignment

• Blink

• ImageIntegration

• DrizzleIntegration (2x, Var β=1.5)

Narrowband processing:

• DynamicCrop

• DynamicBackgroundExtractions

• NoiseXTerminator

• StarXterminator to completely remove stars for starless processing

to be later replaced by RGB stars. doing this allows the nebula to be stretched without worrying about blowing out stars

• HistogramTransformations to stretch nonlinear

RGB Linear Processing:

• DynamicCrop

• DynamicBackgroundExtractions

• ChannelCombination to combine monochrome R, G, and B frames into color image

• PhotometricColorCalibration

• Slight SCNR Green

• HSV Repair

super useful for putting color back into blown out star cores

• StarXterminator to generate stars only image

basically just getting rid of the background

• ArcsinhStretch + Histogram transformation to stretch nonlinear

Combining Channels:

• ChannelCombination to combine stretched Ha and Oiii images into color image

Ha mapped to red channel, Oiii to Green and Blue

• HistogramTransformation to re-linearize HOO and RGB stars images

• PixelMath to add RGB stars only image to starless HOO image

HOO + Stars the math was simple

• HistogramTransformation to bring HOO+Stars pic back to nonlinear state

Nonlinear:

• Shitloads of CurveTransformations to adjust lightness, saturation, contrast, hues, etc. with various masks

• ColorSaturation to selective saturate/desaturate specific hues

• More curves

• Slight SCNR Green

• NoiseXterminator

• LRGBCombination with extracted L as luminance, used for chrominance noise reduction

• even more curves

• color saturation again

• SCNR to remove some green star color

• EZ star reduction

• NoiseGenerator to add noise into reduced star areas

• LocalHistogramEqualization

• guess what baby more curves!

• Extract L --> LRGBCombination again with mask for larger scale background chrominance noise reduction

• Resample to 70%

• Annotation
