Sunday Shots with the 8" Airylab HaT - 18th June

Post by marktownley »

A very hot day on Sunday, but I was out and observing by 6am before the seeing started to take its toll. These shots were taken with the 8" HaT at ~7m focal length, using the double stacked Daystar Quark and the PGR Chameleon 3 using 2x2 binning to give effective 6.9um pixels more suited to the focal length, and, also nice short 3ms exposure time along with (for my laptop!) a nice fast 120fps.

Hoping you've all been getting sunny skies!

Very nice set of images with 8" aperture!

Hope you will have better seeing this season.

Those are very slick and beautiful Mark!

I understand about doing a bit of noise reduction to smooth out noise in processing, but the difference in slickness between your images (and many other here too), and what I'm producing is huge. As one who has been experimenting a lot, I don't get it.

Very smooth and sharp Mark.
You will need to get a bigger chip to bin with :-)
Best wishes,

Cracking images, Mark. These came out really well.

Hi Nick,
Could you post a hi-definition image (Tiff) somehow, so that people can give it a go to see what can be pulled out of your data?

Well done Mark!!!

More cloud and rain than sun here of late...basically May and June have been a write-off both astronomically and agronomically :mad:

Thanks all for the comments! I record 1000 frames for these, stacked 100, this is recorded in about 9 seconds.

In terms of processing it is an iterative process; in a combination stretch, sharpen, smooth. Whenever noise starts to emerge when stretching or sharpening I apply a blur at a radius equivalent to the noise artifacts, then, the process is repeated but small steps more often rather than one big stretch then one phase of sharpen...
