This combines 12.5 hours from the Tandem Tak (Taken over two nights this week with guest Paul) with some earlier TEC140 data for the resolution.

Cameras are 2xAtik 11000 and Yves' SXVH36, all mono and using LRGB. Sub lengths 15 minutes. Processed in AstroArt, Registar, Pixinsight and Photoshop. (Again I flatttened and calibrated the colour in DBE using just 5 background markers, one in each corner and one in the middle, all carefully placed out of the dust.)

Such good colour in the stars; wish I could get that natural look :cool:.

It's mostly having a dark site and no LP filters. I weighted the colours eqaually for the initial combining and then ran DBE in Pixinsight. That does the final colour balance. I used a couple of colour saturation-improving Ps techniques which made the stars a tad cyan so I selected them and lifted the magentas in the blues using Selective Colour. That put them back to their original CB and that's it. The less you process your stars the better in my view.

An impressive image as always!

I really like your smooth looking backgrounds Olly, and I understand that PI´s DBE is a very nice tool. I have tried everything from removing gradients with Astronomy Tools to following Neil Flemings photoshop steps ( http://www.flemingastrophotography.com/gradients.html), but none is comparable to the DBE, wich I got to try once. I wish it was possible to buy a standalone PI DBE program, instead of having to buy the whole package, which is a little bit expensive.

PI does trounce all comers on certain things. It's really very inexpensive given all that it does and the work involved in creating it. Updates are free, too. As well as DBE there's SCNR which is brilliant for green noise, there's LHE at the end as well. (This had a bit of LHE but applied as a Photoshop layer.) I have to recommend it though I do almost all the rest in Ps.

very nice indeed Olly you certainly have

caught the dust in that one, having

your dark site and two photon hoovers on one mount

has certainly paid off,.

Makes you wonder how bigger region the dust goes on for

outside of this picture,

Paul
