Friday Sun, Hα & CaK, 50 and 90 mm

Post by GreatAttractor »

I've started the imaging season.

Material from Friday, shot with Lunt 50 mm and my 90/660 mm achromat, also using Lunt CaK module (straight-through, B600). Everything processed in Stackistry and ImPPG, colored in GIMP. Camera: PGR Chameleon 3 mono (ICX445).

Full discs from the Lunt 50 OTA:

CaK using the Lunt objective and its white tube, to which I attach a 2" eyepiece holder accepting the CaK module (I can barely reach focus, there's no room for a focuser; focusing via sliding the CaK module in the holder). Image quality is mediocre (there's a streaky pattern in the direction from 1 to 7 o'clock); perhaps the objective has aberrations in CaK, or the module is inserted too deep/shallow.

These are incredibly good, great attractor. Your Lunt 50 is excellent, and your processing also.

Some nice images, Filip.
I'm sure you're happy to be imaging again, especially with this action on the Sun.
Cheers.
