Narrative:

After climbing through a large hole in an otherwise overcast (2000') bay area on a left standard departure from pao, I headed towards moffett, where the tops were about 3000'. Pao tower advised that if I kept my present heading, I would be in moffett airspace. I told them that I was already at 3500' and climbing. At this point, the tower asked for a PIREP, which I gave. After a few answers to their questions, I noticed that I had just broken through 4000' and I was directly over moffett. I immediately descended to below 4000' until I had completely passed moffett. I was climbing at an altitude which would allow me to get on top and maintain VFR cloud sep. At the same time, my extended dialogue with the pao controller took my attention from my altimeter and put it outside, making WX observations.

Narrative: AFTER CLBING THROUGH A LARGE HOLE IN AN OTHERWISE OVCST (2000') BAY AREA ON A LEFT STANDARD DEP FROM PAO, I HEADED TOWARDS MOFFETT, WHERE THE TOPS WERE ABOUT 3000'. PAO TWR ADVISED THAT IF I KEPT MY PRESENT HDG, I WOULD BE IN MOFFETT AIRSPACE. I TOLD THEM THAT I WAS ALREADY AT 3500' AND CLBING. AT THIS POINT, THE TWR ASKED FOR A PIREP, WHICH I GAVE. AFTER A FEW ANSWERS TO THEIR QUESTIONS, I NOTICED THAT I HAD JUST BROKEN THROUGH 4000' AND I WAS DIRECTLY OVER MOFFETT. I IMMEDIATELY DSNDED TO BELOW 4000' UNTIL I HAD COMPLETELY PASSED MOFFETT. I WAS CLBING AT AN ALT WHICH WOULD ALLOW ME TO GET ON TOP AND MAINTAIN VFR CLOUD SEP. AT THE SAME TIME, MY EXTENDED DIALOGUE WITH THE PAO CTLR TOOK MY ATTN FROM MY ALTIMETER AND PUT IT OUTSIDE, MAKING WX OBSERVATIONS.
