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.

Nice work Steve, it's surprising how much movement there is. I look forward to watching your progress with this one.

Interesting work Steve.
The movement is a lot and it's incredible to see a movement so big...

Congratulation for this activity and thank you to share this work

Giuseppe

Well done Steve. I don't think that I've previously seen monthly movement shown. I read recently that Prox will occult a couple of stars in the next few(?) months, so it will be interesting to see your animation over that period if the background stars are bright enough.

Wow, top stuff. I would have thought you'd be wasting your time doing anything less than monthly!

Very interesting Steve - quite a lot of movement in only a few months.

Here is July's set added to another
sequence. July's image wasn't easy! Weather conspired to
narrow my "month interval window"
I was finally successful on the 26th July. That was after a rapid
repair on a '97 vintage laptop that drives the scope in DOS. This lappy still
manages to fire to life after all these years! Water had seeped in to
the keyboard and short some keys. Then the imaging monitor decided to
become a fishtank. When I removed it from the dome and held it upside
down, a stream of water poured out of it!
Winter in Adelaide is a cruel, evil mistress.......

The tracking of Proxima is now showing a slight curve. I expected this.
You can also see a background star being resolved that was obscured by
glare in a previous month's image.

August 18-26 will be my last opportunity to get another frame.
A river red gum is going to do me in next time.

Great Steve.
I like what you are doing.
Top effort. BY the way I have pretty good CHAINSAW not being used at present. Let me know. ( trim only).
