NGC 1532 spiral galaxy

[rogerg]

Hi all,

Well the data may be from October 2013, but I've only just now re-discovered the data and processed it.

Of course those familiar with my images will recognise that this is one of the few rare instances I dabble in LRGB imaging :) Success? Well I was hoping for more detail for my exposure time! but it's OK ... colour looks half reasonable to me :shrug: :)

380 minutes (6.3 hours) data.
22 x 5min bin 1x1 (clear)
RGB = 30 x 3min bin 2x2 (each of RGB)

Processed in CCDStack, DBE in Pixinsight, processing in photoshop.

How 'bout that nifty plate solving of astrobin.com 'eh? neat! :D

Regards,

Thats a neat galaxy Roger. I like the dust lanes and the colour you have in them, looks natural.

[rogerg]

A slightly brighter version. Depends which device I look at it on as to whether I should be pumping the brightness up more :shrug:

[MrB]

Very nice Roger

Yeah annoying huh? My old work laptop was my previous standard, which I still process on, but my final check is now done on the new (v2013) Nexus7:

You may be able to mask and remove the blooming apparent on the brighter stars? The galaxy itself looks very nice and structured.

[rogerg]

Yes .. my problem is often that my observatory screens are not calibrated but my main laptop/workstation is! but if I feel like working in the observatory away from the chores of the house, that leaves me with an unpredictable result :) I should sort out calibration of the observatory, but then again, it's screen's are just old cheapo's barely hanging together so probably not much point :lol:



Excellent idea. I'll work on that, thanks!

[rogerg]

Here's one with less bright stars masked. Looks nice but not sure about losing that precision of knowing which stars were actually brightest? :question:

[rustigsmed]

very nice Roger, of the two versions you had side by side, the brighter one looked better on my monitor (not sure if that is any help).

[Amaranthus]

Roger, if you use StarTools you can synthetically debloom and even remove those bright stars altogether. Not sure if this is possible in PI, I don't use that :)

[rogerg]

Thanks, helps :)



Interesting, I am sure there is a way to do it, be it in PI or CCDStacker, but I'll have to dig. I use de-bloom in CCDStack to remove the bloom spikes.

I hadn't heard of StarTools before ... looks interesting ..

:thumbsup: that is a cracking good image Roger.

thats really good roger............. it appears to be affected by something else's gravity!?

All are solid views of this galaxy Roger and the colour looks good too, nice work :thumbsup:

Mike

[rogerg]

Thanks Mike :)



Sure looks like it Pat ... not sure with who though? I wonder about looking at nearby galaxies, or just googling :)



Thanks Ray :)

Nice photo's man. 10/10

[Octane]

Wow, a colour image from you! :D

Looks great to me. Will we be seeing more coloured images from now on? :)

[RickS]

Very nice, Roger, but IMHO you need to bump up the colour a little more ;)

Cheers,
Rick.

Good work Roger!:thumbsup:

Agree with Rick a little more colour and it will be spot on.

Cheers,

Justin.

[rogerg]

:lol: yeap, amazing isn't it :) More? well .. I have more LRGB data to process... but it takes sooo much time! ....



Thanks Rick, consider it bumped :) see attached :)



Thanks, see revised version attached :)
