M 51 From last night 25.06.2012


Recommended Posts

Well good morning folks.

I am typing this through blury but very happy eyes.

My intension was to have another go at the M81/82 pairing but the seeing wasn't to hot so I swung the scope around to M 51.

My idea was to go for 60 plus 60 sec subs at ISO 800. :)

The clouds had other ideas and it ended up at 23 number 60 sec subs at ISO 800. :(

After the clouds rolled in I decided to put into practice what we had discussed the other night in the chat box.

I took 23 darks on the same settings.

I then set up to take some flats.

Stretching a White Tee-shirt across the Newt I set up a 100 watt spot light running through a difuser on a step ladder facing the business end of the Newt.

I then played with the shutter speed until I got the histogramme 2/3rds of the way up.

Perfect I thought.

The timing could not have been scripted any better.

As I pressed the capture button on the keyboard there was an almighty crash in the obs.

I rushed in to find the step ladder had fallen over and I now had a very ex spotlight and difuser.

Oh well scub the flats maybe next time. :(:angry:

What I should have done next is go to bed but I decided to stay up and put what I had got through DSS.

After DSS had done its thing I put the result into PS.

After a quick play the resulting photo is what you see.

To say I am one happy bunny is an understatement.

I know I still have a long long way to go but its getting better.

Nice Graham.

I had a pop at various targets in the NW, N and NE this morning but cloud spoiled every run. I ended up imaging a target I had previously done in the only clear bit of sky I had (SE).

Frustrating but at least I'm getting a routine together now. Imaging time is happening a lot quicker now after alignment, focusing etc

I think it's great there's a few on here all learning together. A trouble shared and all that ...

That's blooming good Graham! Very impressed, I can see I need to extract my digit and start getting my act together. Well done indeed :)

Hi folks.

Thanks for the kind words.

Your right Paul it make it a lot easier to get to grips with when several people are going through the same steep learning curve.

To right Pat,

Just think of it go home from work set the scope running and leave it gathering data for 12 hours.

I can hardly wait. ^_^

As far as the processing goes I think I need all the help I can get. :lol:

Damian, feel free to play with mine all you like, it gives me a bench mark to aim at when I try ;)

:ph34r: I thought that as soon as I had hit the post button... :blush: I think I got away with it last night when I said it was suprising how much difference Pete's extra couple of inches makes. :lol:
