Hello,

I was told that the new moon cannot be sighted with the naked eye at waxing or waning crescent stages until its at about 10 percent... I thought that even at 1 percent it can be seen with the right conditions by the naked eye. Can someone please tell me what is more accurate.

Welcome to BAUT Forum.

Sounds like you've been told about the Danjon limit. When the moon is close to the sun, the lunar crescent spans less than 180 degrees, because of shadowing generated by surface roughness. Danjon extrapolated the deficiency in crescent length, and found that this implied the crescent would disappear entirely when the moon was within seven degrees of the sun. And, indeed, for several reasons (including contrast against the bright sky) it's very difficult to detect a crescent moon that close to the sun.
However, the use of infrared photography has demonstrated the existence of a short deficient crescent at less than five degrees, and observations outside the atmosphere suggest that there are still illuminated glints of lunar surface visible at two degrees from the sun. Whether you would call these observations "crescent moons" is another matter.

Hey Khalili...

I do not know about waning crescents seen with one's naked eye...
personally, i've seen, squinting at sunrises..with about two days to go...

Buut...waxing crescents..there are many breath-taking captures here posted in the 'Astrophotography' section...
Also, check out Centaur's posts in 'Astronomical Observations' sub-folder here. He has posted numerous captures, some as young as nineteen hours.

Are you seriously searching for slivery moon? I would suggest being very careful about your eyes.
Watching or looking for anything near the Sun is dangerous...hurt your eyes and you wouldn't even know it happened...for a while anyway...and then it could be too late. So please be careful.

Hey, I don't mean to put you off, naked-eye observing...the best pursuit...just a friendly tip.
One can get carried away in one's enthusiasm.

...and...welcome to BAUT..

edit:
Hey..I just realised ...this week of Ramadan!!...I gather, it's important...only a few days to go to the nineteenth...
well...clear skies...
