Re: Processing Seestar S50 images

Hi Fabio They are fits images. No derotator, the system takes 10s images and stacks them. Works fine for elevations less than about 80 deg. You can download the individual 10s fits images to use in image processing software such as AA8. The images are also corrected for darks. I’ve done astrometry o...

Demosaic - extracting green channels

Hi

The command "Demosaic RGB" allows the user to extract a single colour channel. However for Bayer patterns with 2 green channels, does AA8 sum or average these two or just pick one?

Re: Processing Seestar S50 images

Hi Fabio

They are raw FITS files. I’d just be interested to know what’s recommended to simply process the images to make them look pretty :D

Cheers

Processing Seestar S50 images

Hi All

I was wondering whether anyone has used AA8 for processing images from Seestar S50. If so, do you have any helpful tips or main processing techniques that should be used to improve the image quality.

Regards

Re: Plate solving parameters in Telescope control Centering

Excellent, thanks Fabio. That’s exactly the process I follow. I was just unclear what catalogue the astrometry was based around but you’ve clarified that it’s the one used by the Star Atlas.

Re: Plate solving parameters in Telescope control Centering

Fabio, Thank you for your rapid and fulsome response - very clear now. If one does a GOTO using Jnow coordinates it makes sense to me to plate solve to Jnow coordinates during the Centre process. In fact after a GOTO using Jnow coordinates, if Jnow is not selected at the Centre page a warning is gi...

Script for plate solving

Hi All Apologies if this has been raised before but is there an existing script (or is it relatively easy to develop one) to make AA8 plate solve multiple images of the same field opened and one time and then save these to the same directory as FIT files? I have a large number of photometry images t...

PNV J17224490-4137160 - Nova in Scorpius

Hi All I was fortunate to discover this bright nova (https://www.aavso.org/aavso-alert-notice-821) a few days ago and once again AstroArt 8 played a big part in that with the discovery and followup. What I find very useful (and somewhat surprising) is that performing astrometry on a 150 square deg f...

Nova Sgr 2023

Hi I was lucky enough to co-discover Nova Sgr 2023 (https://www.aavso.org/aavso-alert-notice-813) and I just like to say that AstroArt 8 played a big part in that. I use the blinking functionality to discover the transient and performed astrometry with AA8 to confirm the position. I use an 85mm lens...

Blink Full Screen negative mode

Hi Fabio Can I make a suggestion for the next Service Pack. When in Blink Full Screen negative mode with the file names displayed, the text colour for the file names is too light a colour and it's hard to distinguish against the negative (white) background. It would be better if the text colour for ...
