Star Testing

Posted By Dmitri Kulginov
At least a half of it is empty talk. The man illustrates diffraction of light through quantum diffraction of particles - used to be the other way round...

The other half is very useful (if you can stand with the first one - I couldn't).

Binoviewers and limiting magnitude

Posted By Dmitri Kulginov
Thanks for the answers! I was particularly happy that one doensn't need binoviewer for galaxies smile

To make a good mirror

Posted By Dmitri Kulginov
Thanks for all encouragement! Unfortunately I cannot follow the most frequent advise - to join a class. Here in Sweden there is one (perhaps two) mirror makers and a handful of people interested in making mirrors.

But it does sound like it's possible!

COPING WITH COLD

Posted By Dmitri Kulginov
Dress in layers, synthetic or wool closest to the body, always wear a hat (knit wool or fur), good mittens, as many socks as your warmest boots have place for, eat hydrocarbons, drink hot drinks and water, know your limits, exersise, use hand warmers, wear the longest down or fur coat you have, stay dry, have clothes to change, bring a cell phone. Easy, really.

COPING WITH COLD

Posted By Dmitri Kulginov
Actually the most annoying side of coping with cold for me is that to dress up takes much longer time than to setup the telescope.

Galaxies in APO

Posted By Dmitri Kulginov
OK, how about faint stars? Unlike with galaxies, I suspect that an APOCHRO will have an edge against an ACHRO here.

M46 and M47

Posted By Dmitri Kulginov
Awesome, Ivan. Reminds me my view at the eyepiece. Also two*) other NGC objects are here smile

Perhaps a shorter exp would show less field stars and make the clusters stand out more.

some galaxies in UMa

Posted By Dmitri Kulginov
I too went through the Messier galaxies in Ursa Major/Canes Venatici plus NGC 4490 and 4244 last night berfore the clouds rolled in. My aperture was five times smaller, but my LM was 5.5. I wrote here once that open clusters are more varied targets than galaxies, but now I begin to doubt...

The highlight of the night was M51 where I could see two bright cores, two separate halos of different sizes and a black space between them at 40x, and also conclude that the bridge connecting them (I knew about it but couldn't see it) couldn't be on the Western side, but could be on the Eastern side (which turned out to be correct). Another great view was The Silver Needle, NGC 4244, quite ghostly and very long at 40x. It reminds of NGC 891 but looks much larger.
