StarTools

Otra versión de Arp 319, el Quinteto de Stephan, con algo más de trabajo en el procesado pero con el mismo tiempo de exposición:

15x30 segundos con ganancia máxima
RC 8"+ Asiair 294MC+Asiair PRO

Cool! But man, Stephan's Quintet is that tiny even through an RC8?

Thanks for the comment!. The FOV depends on the telescope/camera combination, I use the ASI294MC. This combination gives me enough details with short integration times (EAA). For larger fields, I use a shorter RF refractor, with the same camera as well, this allows me to observe large and small objects.

Startools allows me to get good color and maximum detail from these short integrations, I don't want to give up seeing my "photos" as well as possible!

The shot: TSOptics RC8+ ASI585 MC+ UVIR filter. 15x30" stack, Gain 450. Capture soft and hardware ASIAIR PRO.

The ST basic work flow: Bin / Crop (stacking artifacts)/ Wipe (Uncalib1)/ Dev/ Flux (Noise) / Color (Artistic+RGB adj.)/ 1st Denoise ( 5pixels)/final denoise (15 pixels)/ Sharp (mask)/ enhance Filter (mask)/Synt some stars

Very pleasing image
How are you liking your new camera?

It combines well with the equipment, it gives a slightly lower Fov that allows to capture more detail, within the possibilities of the EAA. It is a bit more sensitive than the ASI294 MC and that helps too. I am very satisfied with her.

At EAA you always have to deal with a high dose of noise due to the short number of stacks we usually use. Getting rid of noise is very important to us, even more so than for astrophotographers who have better SNR. Startools has some very convenient tools for that and they are also easy to use.

You're on a roll!

Pretty amazing I have to say, considering these are small faint targets and the integration is about 7 minutes.

A couple things I notice in the workflows - no SVD or deconvolution? Is the integration not up to it? Also first denoise/final denoise. Are you going back and running it twice somehow? Or is that just Screen 1 / Screen 2, which to my knowledge isn't really a stage of denoise but just passes over the pixel grain setting as your starting point.

Thanks for the feedback

I never use Deconvolution, I don't notice any improvement
My English is Google's, so excuse me if I don't quite understand what you're asking...

I use Denoise three times as a general rule, at 5/10 and 15 pixels. This tool allows me to blur grain of different sizes and I apply it selectively according to the characteristics of the object.

My first part of processing is always the same:

Bin/Crop/Wipe (uncalib1)/Develop (Dev)/ Flux (Denoise-2pixels)/Color (artistic-RGB adjust)/ 1st Denoise (5 pixels)

The second part varies depending on the type of object, but I don't spend more than 3-4 minutes to finish the job
