Retired many
years ago, I live part in Jerusalem, Israël and
part in France.
Today, my main interest is the Sun
-
for the full disk:
-- in many wavelenths
like H-alpha, Helium D3, CaK, CaH, etc... with the Sol'ex
-- a
single or double-stack
H alpha PST eventually with a front 2.2x 60 mm diameter lens
-
in high
resolution H-alpha with:
-- a 150mm diameter Cosmos achromatic refractor
equipped with a 160 mm D-ERF front filter, Quark Chromosphere for sunspots
and prominences
-- a Fluorite Perl
Vixen 102/ 900 mm refractor with a Coronado
SM90 BF30
I am also equipped and interested by:
-
ISS
Hires tracking (C8 Edge and recently 125x Coolpix P1000)... I use
a dedicated modified EQ-G mount and Videos Sky software, both developped
by Emmanuel Rietsch !
- Planetary imaging with a Meade 12" LX-200 GP S and 10" Classic,
-
The Moon with the
Coolpix P1000,
-
3D stereoscopic imaging especially landscapes, birds, insects (macros),
- Near infrared (NIR) including 2x A7s
MK1 with one Halpha defiltered,
- Thermal infrared
(TIR) at medium resolution,
-
UV nature photography (using a full spectrum Canon EOS 1100D),.
-
High Speed photography up to 1000 FPS producing slow motion movies with
different cameras and base values, at best a stereo rig of 2 RX10
IV (up to 600 mm zoom !),
-
Lightnings photography
...
To see some result of so many activities, I recommend having a visit to
my YouTube channel https://www.youtube.com/user/sweillerYT and
for ,the Sun, having a look at spaceweather after spectacular events....
I
am day after day grateful to the authors of FireCapture, SharpCap, RegiStax5&6,
Autostakkert!4, AstroSurface, PIPP, VirtualDub, GIMP2,
Deepskystacker, SER-Player & PIPP, Inti, JSolex, WEB site tutorials, etc
...
They
are some of the best amateur astronomy tools !
With Gilbert
Grillot we have developed some utilities in Delphi !
More recently I do this on my own with the help of ChatGPT and Copilot
!
Long time
ago, I have participated
to the beginning of the webcam adventure in astronomy, a time (~year
2000) where
we were
modifying
all
the Philips ToUCams
we could put a hand on.
I was
most active in RegiStax5/6 development, a bit in SER-Player and was a member
of
the SCF (french 3D stereo club).
Even some of my imagery of the Sun has led by
chance to scientific publications
