EAA and Startools

EAA ( Electronically Assisted Astronomy) is not traditional astrophotography, for some it is not even an astrophotography. For me it is a mixture of visual observation and astrophoto light

I like to share this photo so that someone interested can see what can be done with just 12 x12 seconds ( 2,4 minutes exposure total) stacked (Darks and flats applied) and Startools.

I am delighted with this tool that is Startools, without it perhaps I would have been bored by taking photos with short exposures. A thousand thanks to the author, Ivo :bow-yellow:

This is the process that I usually follow:

Bin / Crop / Wipe / Autodev (ROI) / Flux (Noise) / Color / Flux (Sharp) / final Denoise

Since I always serve the same camera, the processes are always the same, even the configuration values are almost always the same.

In total, it doesn't take more than 5 or 6 minutes from the original file to the final result.

In this version I have reduced the Flux / Sharpen and applied a Shrink. I think the bright stars are a little less saturated.

Suggestions for improvement are welcome :thumbsup:

you are getting a lot from your images.
I prefer your last image as the background is less harsh to look at.

I am very grateful that a person with your experience gives me their opinion. The background of the last photograph is not so dark nor the stars so contrasted. The Flux / Sharpen tool must be applied very carefully!

A modern and not very expensive camera can capture many details with short exposures but only good processing can reveal them.

Startools is a soft very easy to use and with impressive results, one of my favorite tools is Color. It is amazing how you can get a real color of the objects so easily.

These three tiny, distant galaxies form a perfect equilateral triangle. The three form a homogeneous group since they are located at the same distance, about 390 million light years, from Earth and their redshift (the speed with which they move away from us) is very similar and reaches 5,200 kilometers per second for the whole group. I have baptized them as Carlos's Triplet. :lol:

Distortions in their spiral arms and areas of intense star formation can be observed in the two largest, which could suggest that at least these two could be interacting. The two are approximately 60,000 light years in diameter, while the smallest is only 18,000 light years in size.

The shot: TSOptics RC 8 + Risingcam IMX294 ( no cooled) + Risingtech soft capture + 12 x 25" stack with máx. Gain


The process has been as follows: Bin > Crop> WIPE> AUTODEV (ROI)> FLUX (Noise) > Color >final DENOISE

Arp 319, Stephan's Quintet, as its name implies, is a group of five faint galaxies (NGC7317, 7318A, 7318B, 7319 and 7320), all within an area of 4 arc minutes in the constellation Pegasus. Four of the five galaxies in Stephan's Quintet form a physical association, and are involved in a cosmic dance that most likely will end with a galactic merger.

The shot:

TSoptyics RC 8"+ Risingcam IMX294 uncooled+ UVIR filter. 12x25" stack ( 5 min. integ. total), Gain máx. Capture soft Risingtech

The work flow:

Bin / Crop/ Wipe/ Autodev (ROI)/ Filter (Noise)/ Color/ final Denoise
