No more Newton Rings ... Easy and Free !!

Camera is simply tilted in Televue 4x, 2", Barlow !

Results (albeit poor seeing) :

Work with regiStax6 on the acquired AVIs is going on (more than a terabyte of uncompressed data !)
and here are the two first astromovies covering the time when the seeing was at nicest ...

Left click to see once or much better right click on thumbnail to download it in Divx and open it with Windows Media Player with repeat turned ON (tested Ok)
or other equivalent software
(Note : strictly for personal use only !)

click here for .MOV and parts 1+2 :

and also I converted a longer astromovie .WMV (note 14MB) and .MOV

20151111, StarMax 2.5 MovingMax result = trajectory visualisation inside the prominence : Right click AVI or MOV to download ([63 MBytes]

Latest development : A time resolution of 1s / image (2000 frames = 2000 secondes of real time (remaining 8000 more seconds to process !)
Each frame of this astromovie shown at 100fps is the result of the registration of 60 original frames with registax6
Multiple use of RegiStax5 with diminishing registering zones (256 then 128 then 64) and VirtualDub to create a rather nicely aligned final movie...

This amateur observation has been useful for a scientific publication :
https://www.cambridge.org/core/services/aop-cambridge-core/content/view/3F931255DABF5A497807D88BABB6315A/S1743921313011423a.pdf/div-class-title-3d-dynamical-structuring-of-a-high-latitude-erupting-prominence-ii-analysis-of-the-coronal-context-and-eruption-div.pdf

I have been asked a detailed step by step procedure ... here it is :)

BTW I am now redoing all the data processing (will takes days of computing) to achieve a 1s time lapse resolution ...
The goal is to have precise data ready to be used for research purposes in order to study movements and masses concerned
on this incredibly huge prominence I was lucky to be able to image !

RegiStax6 & Corono software to eliminate the extra white space
I hope to be able to present a long animation later showing flow of plasma (Many Gb of data to process !)

Fast evolving giant prominence "Lama" and "Alpine Ibex" prominences at 13:03 and 13:55 UT [more contrails in sky]

Two nice prominences (2011/11/13) . The one of the left I nicknamed "the Dancers" and the right one "Forest of Fire" !

Same prominence at 2250mm (Televue Powermate 1 1/4" 2.5x) at the start of acquisitions...
