Sun in H-Alpha

Some images of the Sun in H-alpha from this morning.

Imaging was done with an external SSD resulting in an avg frames per second of 81.

Setting: 

SolarMaxIII 70/400 f/6 DS BF15 ASI290MM x0,5 reducer

Software : SharpCap 4, AstroSurface U4, CS4

Na D1, D2 and He D3 line in solar spectrum

Using ASI224MC on Sol'Ex, I'm able to mark the Na D1 and D2 line but also the He D3 or d line. Capture done using SharpCap 4.

Sol'Ex Spectrum with ASI2600MC

This afternoon I connected my ASI2600MC to the Sol'Ex and TSAPO60/360 f/6. Using SharpCap 4 I made a couple of images of the solarspectrum.

Based on known line I calculated some more difficult lines :

    - He D3 or d line, 

    - H delta or h-line and 

    - Fe I G-Line. 

Sol'Ex - Exploded view

Building my Sol'Ex ... Exploded view. The slit has an angle of 15°. The grating has 2400 grooves/mm. Shortly I will be discussing the theory. 

Sol'Ex with ASI2600MC

 

Some further experimentation with my Sol'Ex. This time I'm using my ASI2600MC color camera. This camera has an APS/C sensor which results in a capturing a bigger spectrum. Getting a larger spectrum was easier to find the absorption lines: eg. CaK &H line, H beta, Mg triple, Na double and H-alpha. I was also able to find the slit, and thus the zero order. 

Saturn: First picture of 2023

My first picture of Saturn this year 2023. It's 17 days before opposition and after a long time a cloudfree night. Seeing was poor and good transparency. The image shows some destinction of the clouds.

First light with Sol'EX

My first light with Sol'EX with TS APO60/360 f/6 and ASI224MC. Capturing was done using SharpCap4 and editing with CS4. Still some learning to do but so far... real cool! I'm to trace back the Ca K&H line, hydrogen Beta and the triple magnesium. In the red spectrum I'm not sure what the elements are.
