General / Software binning 2x2
« on: 2019 October 18 08:24:49 »
What is the correct way to software bin 2x2 in Pixinsight.  Is it the integer sampling tool, or the resampling tool?  I am using a CMOS sensor that does not support hardware binning.
Thnaks,
Rodd

TOA 130 with ASI 1600--about 24  hours of data.  It is surprising what details  a 5" scope can pick up.

Thanks Rodd. It’s 3 hours data through 12.5” Planewave. (1 hour each of R, G and B)
  I think if you triple that you will see a huge difference

Looks good--how much data is there?  is this the 12.5 planewave?

General / Re: Adding high resolution data to lowere resolution image
« on: 2019 September 08 10:48:07 »
How about using high resolution data to insert as a luminance?  That's a bit different--its not adding pictures together.  It is insering the data into a single channel--the Lum channel (or lightness channel).

How to do this?

This is a close in of the famous zoo (llama, dog, elephant, leopard, monkey etc....etc.  This is a crop of an image collected with TOA 130 and .7x reducer with STT-8300. I am used to working with more data--because my sky is not very good. This came out OK considering.  This another target I want to capture with the ASI 1600 and compare, as I feel I over processed this data a bit.  Full resolution is too much.  I guess I should have down-sampled after I cropped so that no further enlargement was possible.

TOA 130 with ASI 1600 and Astrodon 3nm Narrow band filters
Ha 136 300sec
OIII: 70 300 sec
SII" 127 300 sec

I shot this previously using the STT-8300 and felt I over processed the image (there were sharpening artifacts).  So my goal was two fold, 1) it was a direct comparison between the STT-8300 and the ASI-1600 and 2) I wanted to improve the processing.

My goal with this image was to emulate the resolution that Hubble achieved with the core--to reveal space between the stars and not just a blinding glare--kind of like some of the excellent images of globulars taken with very large scopes when the cluster fills the FOV.  Image particulars in the links

I just noticed the particulars are not with the images so: TOA 130 with ASI 1600 and Astrodon Series E Gen 2 filters.  This is an RGB composition with a synthetic luminance made with the green channels stack (The green stack  had a FWHM of less than 2.0, which is good for me, so seemed appropriate).
Red: 25 5 min
Green: 40 5 min
Blue: 32 5 min

2 versions--not sure which I prefer--number 1 for normal mviewing and #2 for full resolution I think.  Let me know if you concur.

Thans Juan--if I am included in the comment.  PI is amazing and I get teh feeling I have just scratched the surface.

Beautiful image--though it looks like a broadband picture.  I have always shot this target in HaSHO--but I like the natural look of broadband for nebula.
