Received Astrodon Tru-Balance 3nm Narrowband 1.25" Filters

Here they are, the last set of filters needed for the filter upgrade. These are Astrodon Tru-Balance Hydrogen-Alpha and Oxygen-III 3nm narrowband filters.

Needless to say that the cash used to pay for these occupies more volume than the filters themselves!

These will be used to both, create 
Bicolour Palette narrowband images and to enhance LRGB images with narrowband data. Now all that is needed is for the clouds to part. Unfortunately, I seem to have attracted them to Gibraltar when ordering these filters, as seems to be the astronomer's curse.
