Hi all,
We are glad to announce version 1.1 of the MARS DR1 database, which can be downloaded from our Software Distribution System. This new version comes with important improvements:
MARS DR1 1.1 Coverage Maps
Here you can see the current MARS coverage maps.
Examples with [O-III] Images
The new [O-III] data can be used to correct HOO images. Below you can see the correction of an image acquired with a mono camera:

The addition of this band also enables the correction of images acquired with OSC cameras and dual-band narrow filters, as seen below:

MARS does not currently include [S-II] data, but the correction of this filter can be done in some cases by decreasing the manual factor ( to very low values around 0.2) of the red channel in SHO images. This should be checked carefully as this solution is strongly dependent on the object we are imaging:

Enjoy!

We are glad to announce version 1.1 of the MARS DR1 database, which can be downloaded from our Software Distribution System. This new version comes with important improvements:
- The exposure time for the Orion fields has been increased from 68 minutes to 11 hours.
- New fields have been added covering the Auriga and Monoceros constellations.
- [O-III] data for all the fields included in MARS DR1. This enables the correction of images acquired with mono cameras and narrowband filters, as well as OSC cameras with dual-band narrowband filters.
