Daylight observations of stars

At about 3:30pm this afternoon I was having a look at the moon through a C8 as the transparency was quite good and the contrast good. With the good conditions I tried to see if I could find some stars using a 9mm Plossl (220x). These were my results:

Antares (mg 1.1) : Very conspicious and showing a striking vivid Orange against the blue sky.

Sigma Scorpii (mg 2.3) : Very easy to see.

Lamda Sag (mg 2.8) : Very easy.

TY1 7377-1056 (mg 4.8) : Not spotted immediately, but once located seen with ease.

TY1 7378-3132 (mg 5.2) : Took approximately 5-10 seconds before located, dim, but not hard to hold in constant view.

TY1 7385-659 (mg 5.6) : Difficult and getting close to the threshold of visibility. Interestingly this is the brightest member of the M7 star cluster.

After this cloud moved in and started reducing contrast, but I am confident I could have got close to mag 6.0 some 2 hours BEFORE sunset!
