Ce;estron CG5 or Skywatcher HEQ5 Pro

Does anyone have any advice on the choice between these GOTO mounts? I shall be mounting an 80mm Revelation ST Refractor to do some basic imaging with the view to constant upgrades, etc. Is there really £200 worth of difference from the Celestron to the Skywatcher?

Thanks in advance folks.

Coronada BinoMite White Light Bins

This is a question I buried in another thread so just to give it another airing as a sep post in case anybody has experience of these.

I wonder if anyone has experience of
Coronado BinoMite White Light 10 X 25 Binoculars
for viewing solar activity?
Telescope house sell them - see link below.
Looks like they'd be great for eclipses (eg 29th March partial!)

Skywatcher EQ5 Mount


The Skywatcher EQ6 mount can handle a pay load of 25kg (50ibs +), can any say what sort of payload a EQ5 Manual mount can take.

As I am thinking of buying a smaller scope to ride piggy back on a Skywatcher 6" Refractor.

Thanks for any help.

Evidence of a Multiverse?

I wonder if these two pieces of research are related and whether it could be evidence of a multiverse.

1. Recent studies have shown that our universe may be expanding faster in some directions than in others, leading to a smartie or M&M shaped universe.

2. Research done at Princeton University has shown that smarties/M&Ms shapes will pack more densely than any other shape into a given volume. Click here for details.

I'm not ...

Solar Projection

To get more out of my scope I wish to try solar projection.
Firstly, as my scope is an SCT, is there a risk to the corrector lens / plate and or the chosen eyepiece regarding temperature. Obviously I do not wish to overheat and risk cracking of any components.
Secondly, I have seen advertised the various types of filter (Mylar etc) to fit over the end. Assuming I had one of these correctly fitted ...

Nothing to do with astronomy.

I know this has nothing at all to do with astronomy (except maybe the Southern Cross on their shirts) but did anyone else see the Aussies getting stuffed by Sri Lanka yesterday in the cricket.
Just thought I'd mention it!!
