M1 - Just a test - But with unexpected Result

[jcm]

A few days ago I was carrying out a final test of my setup. I picked M1 because it was in the east and would be visible for a long time. I set the Atik 16HR exposure to 10mins ( good test for guider ) and set the filter wheel to use the H-alpha and the OIII filter. I also asked MaximDL to take 4 images through each filter alternating between Ha and OIII filter.After 90mins or so 8 images had been recorded. Today I decided to process these images. I was very surprised at the result from a 5" scope. I wish now I had carried on with more exposures.

130mm APO at F6 , 4 X 10mins with Ha and OIII , Atik 16HR camera

I think I will have a go with the C9.25 - should produce a larger image with more detail.

Very nicely detailed Crab, John. The C9.25 should be a cracker.

Turned out well john, I fancy trying something similar with my own set up. I like the idea of alternating the filters between subs and ensuring you get a full set of colour for combining. What did you do with your focus, did you leave it fixed or change it for each filter ?

Blimey, some test John. If you improve on that when you are seriously having a go, you will have done extremely well.

I must say John that is a cracking image.......

A nice capture indeed.......

It sounds like you have an ideal setup now for astrophotography......Lets hope the weather clears up so you get chance to use it........

A great capture John and glad to see it's worked out as an unexpectedly good result as oppose to the usual techinical glitches that we all get from time to time

Hi Mark,

The Astronomik filters are supposed to be parfocal. I used the H-alpha image for the focus and just left the OIII as it was. Both images seem to be in focus.

Nice image, especially for a test.

Never tried M1 in OIII before, it looks good.

Well I would say your test went very well.

Looks great.

Love that one. M1 is fast becoming an obsession with me, those fine details etc. Had a perfect night but just couldnt sort the guiding for it, but the shots that came through were real teasers.

Thats come out really nice, though, like the effect with the different filters.

That's a great test shot, I don't think I've seen it imaged with those filters before. I'm itching to give M1 a good roasting.

That's a great test image, lovely clear shot.

Fantastic well done!

As you say, there is some nice detail in there. Of course, the 9.25" cat will do a nicer job still. I look forward to seeing it.
