Sun in H-alpha, Beta, Gamma en CaIIH line using 2nd Gen slit and TLAPO80/480

Images of the Sun from March 9th with Solex Pro and 2nd Gen slit. As a scope I used TLAPO80/480 with Herschel wedge and ASI678MM camera.

Software : Sharpcap, Inti and CS4

Images: H-alpha, H-beta, H-gamma and CaIIH

Solex and first light with TLAPO80/480 - Best ever CaIIH line

This morning I changed from my TLAPO60/360 to my TLAPO80/480. I tried this before but I couldn't get the spectral lines in focus. After adjusting the connection between the Herschel Wedge and Sol'Ex the problem was solved. According the theory the combination of a 80mm f/6, 2nd Gen Slit of 6mm height and ASI678MM the solardisk would be fully visible. And yes, this was the case. According the same theory the use of a bigger scope should increase details, mainly in CaII lines. And also this was the case. 



Above CaIIH image is my best ever image Calcium image with a lot of details.

Setting: Sol'Ex Pro with 2nd Gen Slit, TLAPO80/480 f/6 and ASI678MM
Herschel Wedge
Software : SharpCap, Inti and CS4
Tilt 1,8° and Sx/SY 6,1; the latter one is cause by the huge ROI for this CaIIH line.

Startrail with Star Adventurer 2i

Update Star Adventurer 2i:
After my colleague, Walter, fixed my issue on the bad "snap" connection, I was able to take again some images of the nightsky. 

First I completed the polarallignment; next I opened my app "SA Console" and connected with the mount. I selected Astro-Time Lapse and took 200 images of constellation Orion.
Postprocessing was done with Startrails and CS4.

When looking in detail, the mount is not always very accurate. But I found out I did nog fixed the altitude bold; not sure if this was the cause.



Setting
Nikon D7500 10mm f/4 ISO100 200x30s
Mount Skywatcher Star Adventurer 2i
Startrails and CS4

Sol'Ex CaIIK Line Stack

After re-adjusting my Sol'Ex time to test. Seeing was very poor but still, I made some images in CaIIK line. The 10 images were made using INTI and stacked uising AS4!.The result was edited in CS4.



Setting
Solex Pro version on TALAPO60/360 and ASI678MM
2nd Gen Slit

Preparation of Magnetogram Fe I 6173A

 One of the conditions of making a magnetogram is finding the right spectrum line. Not that easy. So finding the Fe I 6173 A line (which has a g=2,5) was the objective this morning. Comparing with the solarspectrum and Christian Buil's spectrum, I can say that I found it. Next time, I can start making the images for the magnetogram. I'm not 100% sure but the line split is visible.
