I put together a rather modest setup: the Canon EF 200mm f/2.8 L II USM telephoto lens with an ASI 120 MM camera, and the CaK filter that has given me so much joy while observing Venus, all mounted on the EQ3. The goal wasn’t to image something never seen before, but just to blow the dust off my astronomy gear. I am lazy so I don’t like moving the dovetails around, and I had a piece of hard wood — a dovetail it became.
I’ve seen some really nice prominences and, well, a dolphin :) I mean I was stunned to see a feature just disappear in front of my eyes while chatting (8 hours long recording sessions have their boring parts).
Instruments:
Optics: Lunt LS35T for hydrogen alpha, N 150/750 for Calcium K line
Camera: ATIK 314E 16 monochrome camera
Software: Artemis, AS!2, Registax 6, GIMP
Az alábbi képek a napokban készültek. Lunt LS35T naptávcsővel, 150/750-es tükrössel vagy 102/1300-as MC-vel. A kamera mindegyik esetben az ATIK 314E monokróm műszer.

Lunt LS35T hidrogén alfa naptávcsővel és Scopium webkamerával halásztam a felhők lékei között. A napkitörés-animáció képkockáit a véletlen alakította: amikor látszódott a Nap, filmeztem; amikor nem, hát nem.

The Sun in Hα
I imaged the Sun using a Lunt LS35T Solar Scope combined with a webcam for hydrogen alpha and a MC 102/1300 with ND3.8 and K-line filter combined with a Canon 1100D, both mounted on an EQ3. While far from ideal setups (like full spectrum sensor), I managed to capture some nice shots.
The Hα disk is a mosaic of 8 frames: the solar scope has a very annyoing vignettation. A total of 20 GiB video data was filmed. Eruptions come from the same raws, edited separately and then added to the disk.
The K line images are a stack of 15 photos shot with the DSLR powered by Magic Lantern.
I detail the process below showing the stages of the imaging session in pictures. Processig was done in Canon Digital Photo Professional (raw->tiff16), Registax6 and GIMP.
