A couple of SHO pallet and my first LRGB image.


Recommended Posts

Sadly the weather has been pretty poor for astronomy and astrophotography, but I have made the most of what clear skies there has been.

Working on my narrow band imaging and processing and my first LRGB image. I'm enjoying the new process, combining data, experimenting with data, personally finding processing easier than I had expected. 

First NGC 7000 SHO, 30x240s each filter. 80ED.   Second the Heart nebula SHO, 3 panel mosaic, approx 1.5 hours each filter - each panel for around 14 hours. 80ED.   Third the Monkey head nebula SHO, 30x240s each filter, 200PDS.     Fourth NGC 891 LRGB, 15x240 each filter using artificial L from RGB.  Several smaller galaxy's can be seen with NGC 891

ZWO ASI1600MC, sensor temp -10, 139 gain, ZWO 7nm filters & EFW.

Thanks for looking.

Great images in my view. The Monkey Head is glorious. I might let the black point stay a tad higher, especially in LRGB, perhaps.

It's very mild but there's a strange circular artifact passing through the centre of the galaxy. I wonder what's going on there?

Thanks & Well spotted Olly. 

I had not taken flats for NGC891. The circular artefact is the secondary mirror reflection from my 200PDS, which is partly why the black point is clipped :) 

Cheers

Nige.
