Sun in H-beta - Sol'Ex with Herschel Wedge

The Sun this morning in H-beta. This time I used my Sol'Ex version 1 with Herschel Wedge in stead of Solar filter Hoya ND16.

Setting : TLAPO60/360, Sol'Ex v1 with ASI290MM

Filter : Herschel Wedge Lacerta (1.25")

Software : SharpCap 4, Inti, JSolex2.6.0 and CS4

Line broadening in Sunspots with Sol'Ex

 

Using my Sol'ex (version 1) I'm able to observe line broadening in sunspots. As shown in the image, the spectrallines in sunspot 3759 (upper picture) is bolder and broader that the line in the photosphere (below of the picture). The phenomene is due to magnectic activity in sunspots and becomes visible in metalic spectrallines; in this case Titanium, Calcium and Iron. 

Milky Way Bortle Class 3 - Chatillon sur Indre

Chatillon sur Indre, is located in the département de l'Indre (region Centre-Val de Loire). We stayed four days at the "La Domaine de la Poignardiere".

The first day was almost entirely cloud free and I took my chance to take some pictures of the milky way. The moon was low above the horizon and the domaine was luminated which resulted in a minor light pollution. No other lights from the surrounding (towns) were visible. According World Map 2015 Light Pollution Map the area is bortle class 3:

SQM 21.81 mag./arc sec2
Brightness 0.203 mcd/m2
Artif. bright.32.0 μcd/m2

Setting : Nikon D7500 10mm ISO3200 30-60s exposure tim

Mount : Skywatcher Star Adventurer 2i

Unfortunately, the other 3 days the sky was covered with high and medium clouds.

Visit NASA Space Center Houston - Shuttle OV-095

 

Last april I visited NASA's Space Center in Houston. With my VIP ticket I could visit some really cool area's :

* Crew Systems Laboratory
* Shuttle Avionics Integration Laboratory
* Apollo Mission Control Center
* ISS Mission Control
* George W.S. Abbey Rocket Park Tour with one of the 3 remaining  Saturn V rocket.
 

At the SAIL OV-095 "Shuttle"

OV meaning Orbiter Vehicle; number started with a "0" never flew, started with a "1" did flew. OV 095 was a shuttle to understand how to build one and to test both hardware and flight software. A fantastic experience standing insite of the first ever structure of a space shuttle.
