Alright, this is for sharing of your observation experience. Or, if you are arranging gatherings, star-gazing expeditions or just want some company to go observing together, you can shout it out here.

When you use a glass like that, you not only block out the light from the sun, you also block out the comet's light. :) ... unless you're imaging .. :)

That's actually what we use back in home to see the sun eclipse etc.
Another way is to use couple of times folded film-strip. And these are for the naked eye only. With any optical instruments, it's better to go with more professional ways.

Yeah it works for the eclipse cos you're looking at the moon covering the sun, it's like observing the silhoutte (sp?) of the moon. But if the comet is not within the sun's disc, you won't see it just cos you're blocking out all the visible light. :)

But then again, I've been wrong before .. :)

I wonder whether imaging will be successful , when you use safe solar filters which blocks out more than 99 % of sun's brightness.

It is extremely dangerous to use make-shift filters like welding glass, x-ray films etc

Hi!

I'm sure you can use welding glass for solar eclipse. But for comet, I agree with Jeremy Ng.

Cheers !!!

Actually, Singapore is in the region of Northern and Southern Constellation also can see, except for the extreme N/S ones ... :) It just happens that this particular event doesn't favour us.
