Lightning

Yesterday evening a cold front produced some sever thunderstorms across central Europe, lightning was flashing contiuously for a few hours, here are the best images I was able to take:

Active Region 2339

Today the sunspot called AR2339 featured prominently on the sun’s disk:

the images are single exposures using a Canon EOS 60Da, and a 127mm f/8 apochromatic refractor, using Baader Solar Film ND3.8 ISO100, 1/8000s

Springtime Galaxies NGC 4565 and Markarian’s chain

After I acquired the 127mm refractor I was on the search for an affordable mount suitable for astrophotography, serendipitously I learned that my astronomy club is in the possession of an old but working Meade LXD 650 mount. It turns out, the LXD carries the refractor quite nicely, here are the first images shot with that combination:

 

NGC is a long time favourite of mine, the galaxy is beautiful in the eyepiece as well as in pictures:

Today the sun had some nice sunspots and offered a good opportunity to test the new mount I have on loan from the VAA, my astronomy club.
