Since it is that time of the month again (full moon), I thought I'd rework M1 that I attempted a short while ago. I wasn't quite happy with the results but this time around with a bit more processing I am a lot happier with the final result, though I could still do with lots more data. Not great, but it still amazes me that you can get this with a camera lens, albeit a fairly largish one. A bit of bloat on the bright stars, will have to see if the CLS-CCD filter will reduce that.

Very impressive image with a 500 mm lens. I've had less success imaging M1 with much larger instruments!

Amazing result - very nice!

And that's one tasty lens

[JamesF]

Agreed. I think that's very impressive.

[Gina]

Nice

[StuartJPP]

Thanks everyone, it is always useful to revisit old data since we don't get so many opportunities to get new data.

[ultranova]

Most impressive for 45 minutes,

A lot of detail in the filaments,

A great camera lens combo you have there Stuart,

Well done,

Paul.

Such a tiny object so you have done very well to get so much detail and the colour is great too!

[andyo]

that's a very nice capture as ultranova said a lot of detail in the filaments

[Andy_E]

Nice rework. Your images keep seriously tempting me to splash out on a shiny new astrotrack for my 400mm lens.

[StuartJPP]

Thanks again everyone.

For anyone contemplating getting an AstroTrac, I can highly recommend one, though like most things it needs a bit of tweaking to get the most out of it.

What mount do you need for the astrotrac or can you use any mount?

That's a beautiful image.

That's a beautiful image.

Thanks!

Hi Simon, the AstroTrac sits on top of a tripod. The sequence is as follows:

Tripod-Head1-AstroTrac-Head2

Tripod is a regular tripod, the sturdier the better depending on focal length. Head1 is some form of geared head or wedge to allow polar alignment. Head2 is for aiming your camera at an object in the sky.

[Zakalwe]

Thats a lovely image! And only 45 minutes too

[x6gas]

Just to echo that's a very impressive image considering the integration time and kit used - congrats!

[cyborg421]

Can you use astronomical tripods?

Simon

[psemil]

I believe that you can use any tripod that is strong enough for the weight of the imaging system

Very Good image .... made unguided.

[Raga]

Awesome image. Very well done.

That is superb Stuart, i'm gonna have to look into getting an Astrotrac, the results are amazing
