Power Supply

Hi! I have a car jump start pack that has a 12 volt feed. Is it safe for me to connect my CG5 mount to it for power with the car(cigarette) lead supplied with the mount? I'm pretty sure it is, but don't want to risk it if not certain. Thanks in advance!

Replacement eyepieces??

Hi everyone,

I have a very basic Jessops 800-80 telescope, but have misplaced the eyepiece (they're together in a box that I think went missing in a recent house move!)

Two questions: do I need to replace with Jessops eyepieces, or can I replace with some better ones? If I have to buy jessops ones, any idea where I might get my hands on them?

Thanks in advance!

Which One is Moving?

This speed of light thingamey … and time slowing down the higher the speed and all that … what has always puzzled me about this business is how you decide something is actually moving in the first place, never mind moving near the speed of light. I mean, how do you judge speed? Speed is not a definite fixed measurement, it's a relative measurement, you can't decide that something is moving without relating it to ...

Back garden observatory,

When I retire in eight years time it's my intention to set up an observatory in my back garden. I also intend to start an astronomy club which will include astrophotography...I provide the observatory, telescope (Meade LX 90 12 inch ACF) DSLR Canon EOS60Da and tea/coffee and people provide their enthusiasm and attendance. On the nights when it's just too cloudy for anything meaningful to be achieved outside then my sitting room will double as ...

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.

Hello all, i need some help please. I have just purchased a rather splendid looking Prinz 660 scope. Looks great! But have just spent the last three hours trying to fathom it out. I can see through the 'finder' but I cant seem to see anything through the big lense. Clearly im doing something wrong but goodness knows what. I have got the right angle prism thing in place but it moves about...is it supposed ...
