M45 Halos

Postby christian » Mon Dec 05, 2016 8:51 am

Hello together,

one week ago i tried to capture M45 with my little E-PL7

How could i handle with the halos around the big stars? They look so stairs like, don´t no really how to describe it another way. On smaller stars on the underside it´s blue and at the upper side the halo is orange/red.

Could it be i made some mistake in precessing in startools, or this is because of bad data?

Very much thanks in advance.

Hi Christian,

What lens did you use to acquire this data? Would you have a processing log (in the StarTools.log file) to show us how you processed this?

Hi Ivo,

yes i must look when i´m at home, i processed this image several times, because i like it ;)

I made this picture with an TS 65Q Quadruplet APO and an astromodified Olympus E-PL7, think around 4-5 hours with each exposure 8 minutes.
