M45

[knobby]

Hi, had a crack at M45 last night ... Fullish Moon, a bit misty and a hasty polar align. Managed about 15 x 45 seconds and about 5 x 60 seconds .

Should this be enough to show any nebulosity as the results are pretty limp [emoji3]

All taken at 400 ISO , Nikon D7100 and William optics Zenithstar 70 on AVX mount

Try that, a bit cropped so smaller

Had a quick run in Pixinsight, someone with a bit more skill may get more out of it.

I cropped it a bit.

There are some bunnies and ABE did for some of the gradient.

I struggled with the colour.

This simply isn't a target for moonlit conditions. It would be hard to think of a target worse affected by moonlight since the nebulosity is produced through reflection, so is largely blue - and blue is the colour of the night sky during the moon time for the same reasons that it's blue by day. We may not be able to see it as such but that's the case.

Thanks guys, lesson learned !

Tracking looked good though

I was able to open the original file and had a look at your image. Ihave to agree with Mike:

There definitely is nebulosity. If you improve the PA, you should be able to squeeze more exposure time out of it and reduce the noise.

But for better images you need to take flats. There is quite some vignetting and dust in your system.
