HDD warning.

I bought one of these a few months ago for data backup. I usually use 500GB drives which I have a few of. But I thought, lets go for something bigger. Bad Move!!!
It went pop the other day with a shed load of data from this year. I couldn't even recover it because the drive wasn't even spinning up! so that was a lesson learned. don't put all yours eggs... blah blah.
I'll be steering clear of these in the future.

M13 through Takahashi Sky-90

I just bought a new T-piece coupler for my Tak. I had been using the incorrect nose-piece connected to the EP holder before now, see below.

So here is a full frame of M13 as my first test image.

48min, bias, flats and darks. No guiding 45sec subs.

50% reduced:-

Cropped 70% :-

Here are the bits:-
This is the correct configuration, which gives the correct FR distance.

and this is the old setup:-

The rings fitted together:-

The separate pieces:-

These items were obtained from Green-witch.
CA35 Camera Coupling No 30 - Ref. TAK-TKA35201
Wide T-Mount No 33 - Ref. TMW0004 (not available in Europe, but made up by Green-Witch)
I know that this all looks a bit mundane, but it taken me ages to sort this out without resorting to buying something from the states.

The Sun in Baader K-Line Filter 24th May 2010

... and that sunspot. Using a 5x TV Powermate and Baader H-alpha Pass Filter (656nm) that should really be used for deepsky imaging.

2.5x TV Powermate.

And the nice plage region from the top left.

Venus & Saturn 22nd May 2010

A few B&W's from this afternoon/night.
The IR is a bit blown out, but it shows the cloud detail better, I'll work on it.

M92 with 1 hour of data.

I also had a quick look at M92 before turning in a 3:00am.
M92 is a lovely globular cluster in the same area as M13, Hercules constellation.

Links credit Wikipedia.

M13 - 2 hours 15 mins

Nice and clear last night, so I managed to get some more data for M13. 3 Minute subs at 800ISO.

Softer version below.
