Cassiopeia

Recommended Posts

Busy part of the night sky in the constellation of Cassiopeia. Lobster Claw Nebula, Bubble Nebula, Northern Lagoon Nebula, M52 Star Cluster and Nova Cas 2021 a new star that appeared around spring time as a result of it going super Nova. Targets range from 4,500 light year to 11,500 light year from my garden.

 




5hrs of 4min subs at unity gane 

30 of each bias frames

Bortle 5

AA Wave 80mm

AA 269c OSC

Lextreme filter

Captured in NINA

Stacked in APP, processed in Pixinsight

Nice one, love the colours. The background seems a touch green though.

The tutorial I followed deletes the blue chsnnel and remakes one using the red and green in pixelmath to make a false hubble palette using an OSC. Might explain the numbers you mention. I've no clue as to what those numbers are or how to locate them. Second time using pixinsight. 

The easiest way is to see if your colours are balanced is just look at your histogram transformation in PI. The numbers I refer to are located at the bottom of the PI window, they will show the relevant RGB readings when you hover your mouse over the image. When I looked at the histogram, your black point in the red and green was nowhere near the curve, hence the high readings. This is what it looks like after a slight adjustment in PI. Hope you don't mind.

That looks much better. Feel free to send it me. Any chance you could try show me what you have done to alter it. 

I'll send a few screenshots for you. The top one is the original, showing the histogram. The second one shows the adjustment made to the histogram. Color Calibration should balance your colours without touching the histogram.

This tick thing? 

 

Do I go into each channel separate and do them. Or the RGB tab ? Where are the numbers you mentioned earlier that show the difference?

Go into the seperate channels.

 

Here you can see the numbers outlined. But don't forget to hover your mouse over the image.
