M51 - Awful Framing

Post by gfletcher »

Hi Guys

Tried M51 last night trying to get the guiding in PHD working correctly.
This is the result of 20 subs each 5 mins plus darks and flats.
Had a problem picking a guide star last night so increased the exposure to 3 secs.
I moved the guidescope to enable a guide star to be found but the result of that ended up with me moving the subject (M51) away from the centre of the FOV
Didnt find out until processing !!

Anyway

Details:

250PX
HEQ5 guided
350D modded
CLS CCD Clip Filter
ISO 800
20 subs each 5 mins
5 darks
10 flats
Stacked in DSS
Processed in CS5

cheers

Graham

It still looks very good Graham,
There is also a smaller galaxy below it and possibly a tiny third
I don't know what the smaller galaxy is.
Regards, David.

Nice shot. I like the needle thin galaxy lurking nearby.
Worse would have been to process and find you only had half of M51 :shock: ! But you can always make use of the "crop" function to give the illusion of it being intentionally centred :) .

Hi Graham,
That's a very nice image. Never mind the framing, I think a bit of asymmetry adds interest to an image anyway.
Very nice resolution and the guiding looks pretty good to me. The slight noise could probably be reduced, too, with the appropriate filter.
Nice image thanks for showing,
Best wishes,
David.

Hi Graham,

A good attempt of M51, I like the first one.

That thin galaxy is IC 4263

Dave
