My first M27 - Dumbell nebula

[jimao22]

Hi,

This is my first post on this section and these are between my first images made properly, until now loosing time with upgrading the set-up and learning how everything it works and doing all kind of tests.

So, you have the nebula see it from Romania, with my set-up from signature (AT8IN).

9 exposures x 180 sec luminance bin1

9 exposures x 30 sec R,G,B (each) bin2

9 exposures x 600 sec H-alpha bin1

Stacked with MaximDL and processed level and curves with Photoshop PS2.

No flats and darks.

Sky was average with moderate light pollution (suburban sky).

First picture is a classic LRGB.

Second is H-alpha pure

Third is LHaGB

Fourth is HaRGB

The focus was not properly done to the RGB (I thought the filters are parfocal with luminance and I did not refocused.

First night available I will make some proper RGB exposures and some OIII and SII, to see how can I do mapped colours.
