Re: astrometric indicator on calibrated images

Hello,
thank you for the suggestion.
It's not available, but it's easy to do. I've added it to the "todo" list.
Fabio.

astrometric indicator on calibrated images

Hello, When an image is astrometric calibrated, a Nort/East indicator is visible in the image. I was wondering if this indicator can be expanded with direction of the sun - as an option. This is very useful for images of comets (and maybe other objects) -> see example below. Maybe it is available, b...

Re: Time series Photometry

Hello Jens,
Sorry I don't know any english tutorials for Fotodif.
But it is pretty simple to use (and remember to use US format for separation & decimal points - otherwise it won't work - strange for Spanish software...).
Yet again, may I offer another possibility :D

Re: Time series Photometry

I agree it could be improved.
So for now I use mostly Fotodif software to do photometry.
AstroImageJ is another tool but it is just seems to be too 'scientific' approach for my taste.
Did use AIP4WIN too in the old days (the 'Book' was awesome).

Re: Time series Photometry

Hello Einari. This certainly does some of the wished features. I am missing an option to check out how the apertures are configures. It also seems like this feature only allows ensemble photometry, since there is no reporting of V-C1 and C2-C1 magnitudes. Also, the reporting is only in ADU'sn not in...

Re: Time series Photometry

Have you looked at batch photometry ?
And then you can use option "Follow minor planet" .

Time series Photometry

Hello. First, thank you for creating Astroart, it is such a nice tool for astronomy! I am looking how to do time-series Photometry in Astroart. Time-series is a method where a long series of exposures are examined for variable stars or asteroids, to determine their rotational period. Currently I am ...

Re: Red star borders

Hello Stefan, the halos caused by the glass optics seems normal to me. Compare it to this image:

www.astroeder.com/b33_eder_en.html

Instead, the overall background seems too bright and too reddish, this should be corrected and made similar to that image.

Best regards,
Fabio.
