Good evening, everyone,
some pictures of this morning under a sky (it's not usual) blue
you can see the good weather is back, my cow friends are back
At the fs60 equipped with its sm40 double stack with glasspath x1.25, BF10 and zwo178mm around 09h UT
powermate x2.5 in single stack (75%)
and an animation not very convincing (especially that the camera badly fixed rotated on the end) with 41 films every minute between 11h26 and 12h10 HL
gif reduced to 35%
XVid at 5fps at 75%

Re: halpha sun of April 21st
thanks to you
the rendering of the discs is not tip top, especially according to the scale we display them (in full, it still passes): streaks can appear.
I kind of missed my flat...
as for the powermate, I still can't make correct pictures of the surface (among other things, because of the newton rings that don't want to disappear with the flat... but I still have a second tilt ring to put on and adjust! )
Note that for the anim, the first 20 images were made at gain 100 and 55fps, while the next 20 are at gain 200 and 120fps! (for 900 images per film on arrival).
With the same treatment for the 41 (autostackert3 with 33% retained images), I did not notice significant differences at the end...
cordially,
