Helium D3 Line with Sol'Ex

Imaging the Sun in HeI D3 line with Sol'Ex Pro. Editing using JSolex and CS4.

Saturn Tilting Ring

The image shows how the rings of Saturn are closing. It also shows my imaging skills.

Sun September 21, 2024 CaIIK, H-alpha, H-beta and FeI(c)

Imaging the Sun with my Sol'Ex pro. It's getting better and better. The sawtooth is almost gone with the use of my EQ8 mount. Some images have it slightly but was due to seeing conditions. Not only is the Sol'ex more robust, finding the different spectrallines is also getting faster: H-alfa, beta, gamma, delta, epsilon, CaIIH and K, Sodium (Na D1 & D2), Helium D3, MgI b1, b2, b4, FeI(c). 

Setting: Sol'Ex pro on TLAPO60/360 and ASI290MM

Filter : Herschel Wedge

Software: SharpCap, Inti, CS4

Saturn Stack with IR742nm filter

Imaging Saturn with TAL200K f/8.5 with barlow x2 and ADC. This brings effective focal point to f/25.68. This time I used a bandpass filter IR742nm. The result was stacked with image taken with IR/UV blocker. The result shows much more details.

Setting:

Scope: TAL200K @f/25, ASI224MC on EQ8

Camera: ASI224MC

ADC, IR/UV blocker, IR742nm

Software: SharpCap4, AstroSurface, Winjupos, Stellarium, CS4

Sun September 20, 2024 Flare AR3831

Imaging the sun with Sol'Ex on sept 20, 2024. By accident a flare was observed in AR3831 but only in H-Beta and CaII H and CaII K.

Setting: Sol'Ex Pro, TLAPO60/360 with ASI290MM
Herschel Wedge

Mount EQ8: sawtooth almost gone compared with my EQ6

Software : SharpCap4, Inti, CS4

Sun in FeI(c) line with Sol'Ex

Imaging the Sun with Sol'Ex pro in FeI(c) line (495.761nm). Both traces of the photosphere and chromosphere are visible. Conditions were good.

Date : September 14, 2024
Setting: TLAPO 60/360 with Sol'Ex Pro and ASI290MM
Herschel Wedge
Software : Sharpcap 4, Inti, JSolex and CS4

Doppler Prominence

Solar Images with Solex and Sawtooth effect

Imaging the sun in the morning of september 14, 2024. I'm having some issues with sawtooth effect on the edges of the sun. The cause could be the mount scanning performance and/or turbulences. The figure out what the cause is, I used my bigger EQ8 mount. As a first conclusion: the sawtooth effect is much lower but on the other hand, the seeing was very good. This work will be continued.

My first Sol'Ex image as part of ProAM

 Today my first Sol'ex image is available on Bass2000 as part of the Sol'ex Pro-Am program of Observatoire de Paris.

For my image see this link (August 25) : https://bass2000.obspm.fr/get_obs_simple.php?id=325603

To upload my images, the ser files are prepared by Inti using the setting in the advance section.

To upload the file, Filezilla client was downloaded and connection was made with FTP server. Files are dragged from my local drive to FTP server.
