M57 & M13- 3rd June 2010

30x10sec per colour. Plus 10x10sec darks.
Just messing about, it's too light to do anything serious!

M13 40x10sec no filters.

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.

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.

M13 - 25th May 2009

20 minutes worth of images, uncropped. C9.25 prime focus & guided with PHD.
Although the seeing wasn't very good, I think it turned out OK :-)

M13 colour version from quick 2500ISO test.

Two versions using slightly different processing techniques.

Test shot of M13.

21 x 10sec frames using Canon 50D @ 2500ISO.
C9.25 prime focus, unguided.
I had problems with the colour, so I converted it to B&W.

Yet another M13 from the other night.

11 minutes @ 400ISO.

M13 from 26th April 2009.

Here's one that I took of M13 the other day using the DMK camera on the Tak.
I'll have to take some RGB later and use this as the luminance.

M13 - 25th April 2009.

First light with Tak. Widefield unguided image with 20 second subs.
Seeing was not very good, transparency was about 7/10.

Just spotted this, a satellite going straight through the middle of one of the frames from my 2nd May M13 session.
