Daytime Mars new
      #6278752 - 12/29/13 09:36 AM Attachment (21 downloads)

A bit different for me this observation. I have just finished re-spacing an Achromat refractor lens and woke up
too late (or so I thought)for planetary observing.

At my location the Sun rised at 08:26 UT, this drawing was made at 08:45 UT. Telescope was a Sky-watcher 120mm f/8.3 Achromat
(with re-spaced lens to correct under-correction) at 175 - 200x power in Binoviewers. A #12 Yellow filter was used, hence the Yellow background.

The NPC and dark collar was very easily seen, as was the shape of Acidalium. Towards the southern region,
darker shading was visible. Also detected some limb brightening at around the 5 o'clock position on the drawing.
It made a change to be observing in daylight.

That's good detail considering it's size/distance.

Probably the early daylight conditions helped slightly.

Terrific details, Rutilus! They say daylight is a good tool for relaxing the eyes to assist in contrast detection. I will say that I have experienced this with both Jupiter and Saturn in the past, although both experiences were prior to my sketching days. You are the second to post a Mars image this morning and I am now feeling pumped to give Mars an early morning spin.

What??? Daytime observing? I must say I've never tried it in the past, but now that I've come to think about it, it makes sense on the planets. Perhaps I should also give it a try. Nice work, by the way!

Excellent early morning observation. I see a lot of observed detail in your sketch.

Peter, you can't see M78 in the daytime. Can you?

Rutilus, man, you're nailing Mars. Well done. And thanks for the view, you proved to be right about being able to see detail there. Not sure I got that much just yet, but Mars observing has jut begun. After Jupiter, mars seems to take a little getting used to.

That is a fine morning sketch of Mars. Some of my best views of Mars have been in the daytime with very transparent skies.

Well, now that we know that we do NOT have to get up at 4 a.m. to observe Mars there will be many more "daytime" observers.
