Leo Triplet with 4 inch refractor
      #6459570 - 04/11/14 02:29 AM

Hi,

The same night I sketched M51, I went for Leo triplet.

M65 and M66 are really hard, I did detect an "S" structure inside M65 at high magnification, which finally was one spiral arm a bit more brighter than the other.

I think it has a lot more to offer, but that night the transparency was not at it's best.

Regards,
Manuel.

What? You've seen the dust lane in 3628 with a 4"? That's absolutely amazing! Congrats!

Nice work! You must have some lovely dark skies. I always love seeing this trio in the same field of view.

Hi,

Thanks!.

The dark lane is pretty small and not contrasty. With high magnification and patience, you can see it.

My skies are around 21.3-21.4 (old SQM) or 21.6 SQM-L. Not specially dark, but having a weekend house in such skies is something that was out of my mind some years ago.

Regards,
Manuel.

Manuel,

An excellent observation of the Leo Triplet using your 4 inch refractor. You recorded some detail over the galaxies. Thank you for sharing it with us all.

Regards,
Carlos

That is VERY, very deep for 4". Good use of magnification. I noticed that (although it is almost always clear when I go observing) between passing clouds one can occasionally achieve an unusually deep view. Possibly because of better dark adaptation - when the clouds look black, like they do at a site like this. And possibly because they somehow scour the sky of haze.
