Proxima project

One of my imaging projects for several years now has
been to capture Proxima Centauri's motion against the background
stars over the course of a year.

Years ago I started to accumulate data at various focal lengths and
the data is quite a huge set. Pretty hard to manage and calibrate into
an animation without a lot of manipulation...and time.
One day I might get to it.

Until then I decided this year to do a set at an exact image scale every
month, the purpose being to have a set that is easily calibrated
and turned into an animation quickly.
So far I have 6 months worth.
I'm not quite sure how long I can go, I suspect at about the 9 or 10
month stage Centaurus will be in some sort of twilight or dawn so the
full year might have a 1 or 2 month gap.

This set has an imaging F.L. of 1524mm and uses my home cooled DSI II mono.
Only filter used is a Baader IR.
This is a crop of a fairly narrow piece of sky.
Understandably, a lot of curve manipulation and normalising is needed
to make up for imaging differences each month. Seeing/Moon/CCD temp etc.
