Got a beginners' question? No matter how elementary, our friendly forum community and magazine writers will answer it.

Real time, Time lapse or slowed? Real time, Time lapse or slowed?

Can someone make clear how video presented on SaN, or elsewhere for that matter relates to real time and whether we should assume it is real time unless told otherwise?

I've never been clear, and it's not obvious whether time lapse or slowed frame rates have been used with astronomical video. For example, in a video of the Sun on a recent SaN disk the footage is, I assume, in real time. The implication is ...

What Improvements from Collimating?

Hi guys,

I've got a Skywatcher 1145p and invested in a nice Baader Hyperion 13mm EP. I get ok views on Jupiter but can only really make out 2 cloud bands, I was hoping to see the GRS!

The magnification is 38.5x with this combination and with a 2x barlow (cheap one that came with the telescope) does not really improve making out detail due to the colour distortion it creates.

So, i quickly checked ...

White streaks across night sky

I have noticed for the last two nights 2 large white streaks across the night sky. Much to big for any plane to have made. Is this something to do with the asteroid / meteor shower? Never seen anything like it before.

Synscan Rates

Pardon my lack of knowledge, but still learning, a lot.

I got a synscan upgrade for my EQ5 for Christmas. Among other things I am confused about Tracking Rates.
One is obvious, "Lunar Rate"
The other I need some help with,
Sidereal Rate:- Is this for Deep Sky and star tracking?
Solar Rate:- Obviously for the sun which I think is a constant rate, but is this also for Planets? Doesn't planets track at different ...

DSLR photography of the sun

The other day I was leaving work and saw the sun behind thin cloud, low on the horizon and I though it would make a great picture. I know it's dangerous to view the sun directly. Is it possible to get filters for DSLR cameras that make it safe / possible to take direct pictures of the sun?
