Gemini - Brothers

After we had all the excitement about the wonders of orion constellation, we move to Gemini, which is located north east, next to orion's right arm.

Castor is a visual binary, it is seperated nicely under 220x.
Eskimo (NGC 2392) and M35 open cluster are the enjoyables among my 16" in santa clara, to find Eskimo, we start from the torso star of the elder brother (delta), in the finder, there should be three bright stars (5 mag) north east ward, they are forming a 'L', move scopy among the upper part and start to scan within EP. Eskimo is a grey/bluish planetary nebula, enjoy!

M35 is near left foot of younger brother (eta Gem), center the finder on it, M35 is on the east edge of the finder, there are several dim nebulas within finder circle, IC443 is between eta and mu, IC444 is around north of eta, SH2-247, NGC 2174/2175 are in south area, they are just dim, requires 5-10 hours of exposure to capture
