Authenticity of Image

See attached



can this amount of detail and resolution actually be achieved using a SeeStar, the imager claims 45mins, bortle 4, S50. Processed in SIRIL, graxpert, astrosharp, and lightroom. Used the deconvolution on the graxpert beta rc2.

Hi Trevor, yes it can. I am very happy with the results that the seestar can produce from my front yard. I am a bortle 8 here, with very large lights in the surrounding area. Here is one of my seestar S50 pics:

Ok but the Seetar has a 50mm lens so the FOV would be a lot wider not this close up and a resolution is only 2mp, what processing magic is taking place -

It is due to the size of the sensor. Being very small, it give a much tighter field of view. I think I remember reading it was similar to a 1700mm f/l. The same as how a crop sensor camera give a more zoomed in view that a full frame camera with the same lens.

I have read otherwise re the Seestars FOV being a lot wider than shown in the image an image like this requires a fair bit of software manipulation to achieve.

Hi Trev,
Yes, it does require quite a bit of processing to achieve an eye pleasing result.
I think that the processing is no more difficult than processing with my zwo 533 MC or any other color astro image processing.
The field of view in the image you showed is about what you would get out of the Seestar.
When I did the Rosette nebula with it I use the mosaic mode and that way I was able to get the whole thing in.
