hi ,ronSo what is your question about the circuit?
hi, deltaHello there very good questions. If you read this thread in its entirety you'll find your answer it's a very common question and a very good read.
how mod adjusted the image?
i guess the osilation circuit you recommended is different with mine"
On the contrary!
The component values may be different, the 330Ω resistors and the LEDs are positioned differently. The function is identical.
If you take the time and read the entire thread as I suggested
It will answer every single one of your questions.
Although it is not as personal as I am talking to you right now .I will only be repeating what has already been stated.With that said... if you have any other questions please feel free to ask. And the schematic in the other thread wiggles.

No, they are not.Your base resistor values are way too low
Now the base resistors are way too large. Assuming the Vf of the LEDs is approx 2.0 V, the ratio of collector current to base current is now 80:1. I'm not a huge fan of the 10:1 rule, but 80:1 is way too high, even for me. With the original resistor value it was 7.4:1. I suggest you increase the base resistors to 10 K and decrease the capacitors to 100 uF. The net change in frequency is 3%.I increased them 10 times and reduced the capacitor values 10 times so that the timing is the same.
