This weekend I took my chance as a clear sky was predicted south of Belgium. My car was packed with all nescessary material including food and hot drinks. Special winter clothing due to freezing temparatures. I left early in the morning and picked of Walter to support the test. Destination was Spa-Francorchamps. Weather was perfect with a blue sky and an open space filled with snow.
For the test I used my EQAZ6 with Sol'Ex Pro and ASI678MM camera. My TS-TLAPO60/360 was also equiped with a Lacerta 2" Herschel Wedge. The mount was powered with a battery and PC with a Power bank Xtorm (in case of...).
Conclusion:
Weather conditions were very good, transparency and seeing very good.
H-Alpha and H-Beta images with a lot of details. CaIIH en CaIIK have more details but unsharp. I made aswell images of Na D1, D3 and He D3; Mg b1, b2, b3.
My first image of H-alpha had a redshift of a filament of an incredable speed of 470.000 km/h (131km/s)
Second generation slit of 7micron gives more and finer details.
Setting:
Software : SharpCap 5, Inti, JSolex, CS4
