Mimosa and NGC4755

[TrevorW]

Well out under the light of the full moon last night in a vain attempt to capture some decent photons



This little gem is a widefield of Mimosa and The Jewel in the crux only managed 35 minutes of data before they disappeared below my roofline,

please follow the link for images and details etc

or check it out in the slide show under clusters on my website

I've also captured a similar shot of Antares and M4 but still trying to remove the moon glow gradient from that which is a killer before posting

C&C

[multiweb (Marc)]

Very nice star colors. Well done.

[Hagar (Doug)]

Nice one Trevor. The moon is a problem.

[TrevorW]

Thanks Marc and Doug

still trying to fix the Antares one the gradient is very bad as both so relatively close to the moon

[desler]

Dedication being out there in the full moon Trevor, nicely done!

It was like daylight last night on the freeway with that moon.
Some clear dark skies, without a force 10 gale would be nice.......

Nice widefield there, Trevor. As the others have mentioned, nice star colours

[TrevorW]

Thanks Carl

can anyone help identifying the two faint blue fuzzies at 9:00 and the one at 3:00

[TheAstroGuy (Shane Ross)]

I like it!!

Out in the light of the full moon still imaging and not even in narrow band, Go Trevor! and not a bad shot either, nice tight stars and i like the subtle diffraction spike you got there.

Regards

Shane

Can you mark the ones you mean on the image? The only PN in the area is PN 302.2+2.5 (aka Pk 302+2.1) mag 16.3, right (south) of Mimosa and up from NGC4755.

Pleasing scene and nicely framed shot

I'm not sure if the original size on the site is true to the original size of the image uploaded; but there's alot of over-processing which has washed/blotched the stars in the image? The fuzzies mentioned look like blotches caused by the processing when viewed at the original/large size?

Keep at it. Sometimes those darn' gradients just can't be beat.

[TrevorW]

Thanks Dan you are probably part right in that one may be an induced artifact by trying to remove the gradient but the other one may be PNG 302 as suggested by Andrew refer cropped frame attached arrows pointing to objects

It's too purple and the sky is too black to my taste. Sorry.

[TrevorW]

Thanks Luigi I'll have another look at the colour problem is the image is probably a tad clipped to deminish the gradient from moon glow etc

[leinad (Dan)]

I must say that frame to my eye is much more el'natural and pleasing to view. Yes, those objects shown are much easier to distinguish now.

The higher magnitude stars don't appear round but double spiked, and I've seen this with my images when processing bfore, but I can't put my finger on how it is caused at the moment(tired , memory bad) but I 'think' I've seen this with a certain stacking method or too strong deconvolve routine?

Those are the ones I thought you meant.

In your image North is to the left, West is up. PN302.2+2.5 is 57'9" almost exactly due west (PA is 270deg 21') of NGC4755. I'm pretty sure it is inside the yellow circle, but it's mag 16.3

The notes for it are: Close pair of mag 12 stars with mag 10.16v star N 2'.6; mag 13.1 star ESE 1'.1
