Sun in Ca H, Ca K and H-Alpha

This morning a clear sky for solar observation. After focussing my Sol'Ex pictures were made of the Sun in Ca H, Ca K and H-Alpha.

Setting:

TSAPO60/360 with ASI290MM

Sol'Ex with Hoya 1.6 SSD 

Ca H , Ca K and H-alpha 

Speed : 8x, Capture Area, 1936x276, MONO16, binning 1x1, capturing with SSD

CaH and CaK Exposure : 10.23ms ,tilt -10

H-Alpha Exposure : 3.75ms, tilt -3.9
Software : SharpCap4, Inti, IMPPG and CS4

Sun in CaK

Sun in CaK using my Sol'Ex instrument. Details of supergranulation and CaK prominences are clearly visible.

TSAPO60/360 with ASI290MM
Sol'Ex with Hoya 1,6
Area: 1936x114 (CaK) 
Ca K: 70fps, gain 49, 14,2ms, Mono 16, binning 1x1, Camera temperature 34°C
Software: SharpCap 4, Inti, IMPPG, CS4
Use of false colours

Sol'Ex second session

My second Sol'Ex session after adjustment of the slit and slit edge. The edge of the slit was sharpened by pulling out the collimator bloc. Important is to keep the lens fixed and only pull the collimator with the slit out. It's only a mm. After sharpening the lines you will see that both lines and edge are sharp.
My first time I captured prominences in Ca K wavelengt.

Some other learnings: 

1. allignment of the Sol'Ex; the plane of the Sol'Ex is parrallel with the equatorial plane
2. at start the tilt was about 4°; when slightly adjusted this was reduced to -0,4°
3. calculating the exposure time based on a speed of "8". this is about 8ms

Setting:

• TSAPO60/360 with ASI290MM
• Sol'Ex with Hoya 1,6
• Area: 1936x114 (CaK) and 1936x276 (H-Alpha)
• H-Alpha : 115fps, gain 0, 8,6ms, Mono 16, binning 1x1, Camera temperature 32°C
• Ca K: 70fps, gain 49, 14,2ms, Mono 16, binning 1x1, Camera temperature 34°C
• Software: SharpCap 4, Inti, CS4
• Use of false colours

What to see on Jupiter

Imaging Jupiter GRS and Moon transit

A visual observation of Jupiter with it's Great Red Spot (GRS) is already a beautiful view. Using Winjupos I simulated when Jupiter's GRS is showing up together with a Moon Transit. This combination is even more beautiful both visual as photographic.

See below images with dates of  GRS and Moon Transit combinations: 

Sept 29 UT1h

Oct 3 UT3h

Oct 6 UT2h

Oct 16 UT18h

Oct 20 UT21h

Oct 23 UT19h

Oct 27 UT23h

Oct 30 UT21h

Nov 5 UT5h

Reworked Jupiter with Calisto Sept 8, 2023

 

Reworked picture of Jupiter from Sept 8, 2023. Use of 500 out of 10.000 frames using AstroSurface U4.

Saturn Sept 8, 2023

 

Very good conditions on Sept 8, 2023. This results in my best Saturn picture this year with a lot of details.
