Milton, The sunspot in question is I understand quite prominent although it was miniscule in the eyepiece. It`s no wonder I missed it given what we`ve been discussing about magnitude limits on both the Flea 2 & later the Scorpion. When I changed cameras the iBook`s cursor froze & I had no alternative but to shut down at the power button & couldn`t re-start it readily.. (this problem is probably due to the work I did on it- I changed both the memory chip-from you- & the HD to a 250 GB one). I had no alternative at this stage but to resort to my monitor etc. on the long cables.(which I used agin tonight planning everything like a military operation by comparison..) Given the annoyances I was encountering from both the heat & the constantly stinging flies it`s a wonder I got anything done. Last night the march flies had gone but it was mosquito time so I sprayed some fly spray around before starting-repellant is always at a shortage around here...It was a first attempt at this for me too!

Mark;

1) Achieve focus on the Limb area
2) Decrease the exposure / brightness so that the disk isn't a big white blob. That's why you can't find that small sunspot, it's lost in the glare.
3) Move slowly when you sweep across the disk and pay attentions to the screen.

HTH..
