This time, a rather aggressive processing, maybe for the better, who knows.

This optical tube is a marvel, at least with the Calcium K filter. Although there are some stacking-aligning issues left on the picture above, it is still the best I have ever made.

This is the first light of the APO tube I just bought, and put into the lunchbreak-heliobservatory: ASI 178MM (cooled), Baader K-Line Filter 1.25″ (double stacked), TS-Optics 76/342 TS76EDPH, mountpusher, EQ3-mod
I really like the design of the tube, how short it is, though its focal length needs either an expansion tube or the flattener, which I figured wouldn’t be a good fit for the Sun.
The tiny additions I put onto the tube: the focuser and the cardboard adapter for the ND3.8 filter I already have for the MC102/1300.
It was a really nice surprise to see the Sun in much more detail, than through the Canon EF 200mm f2.8L II USM

The Sun in CaK
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).

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.
