G'Day Darren,

It sounds like you're on the right track.

Please, make sure it's a solar filter before you use it! It's just not worth "assuming"!

It's also a good idea to inspect it thoroughly. It is is scratched or has pin-holes - don't use it.

Make sure it is securely fastened to the scope so it can't fall off, and do the same with the lens cap on the finder.

Now, onto your question... i.e. how to find the sun... Use the shadow of the scope to point it. When you OTA is perfectly aligned with the sun , it's shadow will be circular (OK probably a perfect ellipse on the ground). I usually watch the shadow of the front cell of the scope on the OTA to do a rough aim. Then when the front cell casts a shadow along the whole length of the OTA I watch the shadow on the ground to fine tune, which can usually be done accurately enough to pick up the sun in a wide EP.

Hope this helps,

Al.
