NGC 2903 L

[Ibbo!]

After the Deep Sky Stacker thread I reprocessed this image

If fact I redid the calibration frames as the flats were too strong and went back to Maxim to stack the images

Curves and levels with a slight sharpening and an increase in brightness (as for some reason images come out much darker when uploaded to the web on this PC)in PS2 and saved as a jpeg using PS routine

It was taken with the Tak FS102 with a SXV H9 and consists of 33 600s exposures calibrated using darks and correctly calibrated flats

Please I need feedback as to the appearance on the web

Cheers

Steve

This one looks good on this PC

[davew]

On my screen the first one looks a bit light and the second very dark.

The second one also shows that the flats aren't working at all well. Large dark bunnies, one light and bad edges.

Sorry.

Dave.

[Ibbo!]

Thanks Dave

Thats what I thought might be the case

I'm not sure what to do now as the monitor is calibrated

its just that when its converted to a jpeg it gets a bit dark then darker still as it is uploaded here

[davew]

I wonder if it's embedding a profile you don't want ?

I've never had a jpeg look the same online as on my Laptop.

By the way, the stars and galaxy look good

I'll invite all round here as it looks good on my monitor

anybody got any hints about profiles please

[SlipperySquid]

First one looks ok if a bit light with a bit of noise (get hold of Neatimage for photoshop, it's excellent!) second one has a lot of gradients to the left and large black circles!

All my images look different on my pc's

[Ibbo!]

Its the same image with altered brightness

thats what is confusing me

[SlipperySquid]

Looking agian mate I can see the circles in the first image also? Look like water droplets??? dew?

[martin_h]

I get those circles on my images - I think they are caused by filter reflections - but my flats usualy get rid of them.

[davew]

Those particular circles look like dust on the filter to me. Could be wrong.

Ibbo, you couldn't have the flats and lights 180* out could you ? Nah don't think so. I come up with all sorts of rubbish at this time of night.

Dave.

I reckon there is a fair bit of muck on there as the optical window was dewed up the other night

will pop out to the obs when its stops raining and have another go with the flats
