A slight haze nearly stopped me setting up, but seems like it was worth it.

Excellent animation Alex!  Well done!

Thank you! The animated gif looks better, but the forum doesn’t like the file 😞

Dead link  !

Replaced the avi with and embedded mp4

This is from 10am till 11:50 today, 2000 frames then a 1 min wait (nearly ran out of disk space!). 81 frames total in the animation

Stacked in AS!3, processed in PixInsight & aligned in imPPG

Earth added for scale...😮

Daystar quark, 2 image composite of AR 3032 heading over the limb and AR 3038 in the image centre

Slightly lacking inspiration on my one clear night, but this seemed like something that might be reasonable boxed off in a night

Great image and excellent colour balance.

Thank you! I find balancing the colour takes up most of my time in processing.  

Captured as 2 panels per channel in LRG&B with an asi178mm @ 700mm

Stacked in AS!3, then sharpened in PixInsight before mosaic merging with MS ICE, aligning in imPPG then off to Photoshop for colour balancing and saturation etc

Morning! I had another bash at your data, this time stacking it from the raw data (PixInsight Weighted Batch Preprocessing, Maximum preset)

 Once stacked, I did a background extraction, stretch then Starnet2 to preserve the colour

Beyond that it was mostly curves works and a rotation (sorry!)

A grab before work (and clouds!). 2 panels: AS!3 -> PixInsight -> Photoshop (manual alignment, blending and colour)

My processing workflow amounts to trying stuff and seeing if I like it 🙂 This is my take:

Dynamic Crop
EZ Soft Stretch
Histogram transform (Rough colour balance)
Curves (Colour balance)
DarkStructureEnhance script twice. One at .40 and then one at .20
NoiseXterminator (just a light touch)
SCNR to settle some remaining green
ArcsinhStretch a tiny amount (1.4, I think )

Thank you for the data!

Very nice capture, and excellent colour balance.

Thank you!

Last nights (14th) 95% waxing gibbous moon. 8 part mosaic at 700mm with a QHY5iii462 colour camera, which is usually my guide camera. What a delight to process after doing so many with a mono camera!

A different kind of task, compared to mono. With my 178m this would have been a 2 part mosaic, but still 8 stacks (LRG&B).

Nicely done! It's very clean and crisp at 100%

This was shot with a ProPlanet 642BP in lieu of the red channel, as the red seemed a little soft when processed (PixInsight, ICE, imPPG)

2 panel mosaic @700mm with the asi178mm. 1000 frames per channel / panel, 30% stack

10 x 240 sec of luminance dusted with 5 x 240 RG & B. I few sat trails sneaked through the pixel rejection, but nothing too bad

It feels different to capture something so vanishingly fleeting as 62/63 million year old light zipping past in a tiny window of time

I assume you're using a largish aperture scope? I ask as I've taken a similar level of exposure with a WO Z61 in a bortle 7 but have very little cloud/dust detail at all, just the initial patch around the bright centre, nothing beyond the internal cloud/dust surfaces.

The scope is an APM 107/700mm. It took some effort to drag it out of the background

Awesome, is that 4 hours of each l, r, g, b or 4 hours total?

Thanks! It's 2 hours of Luminance, and the rest is 40 min each RG and B

The Iris Nebula, dredged out of the background sky of bortle 6, around 4 hours worth of LRGB

Pinwheel Galaxy, M101. Just over 4 hours of LRGB+Ha

Cheers everyone! Hoping the wind dies down before this group vanishes over the hill 🙂

Wow,  that is something to behold.

Excellent work all round.  161 separate movie captures (!!!!).   Your poor computer must be as hot as the Solar surface.

 

 

Thank you! I'm amazed that this sort of thing can be done as 'backyard' astrophotography. 

The computer chewed on the files over night - I off load them to a NAS so the capture PC drive doesn't fill, so stacking speed is further limited by network speed

Must get a faster PC this year with plenty of solid state space
