And what a beautiful edge-on sprial galaxy this is! I made almost 3 hrs of 120-second frames with the ASI183mm Pro and the Esprit. Then I combined the resulting monochrome (Black/White) image with the older C11/Nikon D750 color frames I had from last year. This process included debayering of the color frames into a Red, Green and Blue version. And again recombining an LRGB with the monochrome and RGB frames. Finishing in APP (Background neutralisation, removing Lightpollution ) and in Photoshop.

**This is the monochrome ASI image. It is wortwhile exploring it a full resolution in Astrobin, detecting the many little galaxies in the background.**

Since the Field of View of the Esprit/ASI is much larger then the C11/Nikon, this image was cropped to fit the color frames.

These are the measured currents that the equipment draws, mount without equipment mounted (bare mount). The 12V DC converter used, was a 3,7A AC/DC converter that originates from a Wii gaming console.

I measured the current required for the divers equipment I’m using:

Equipment or combination	Current in Ampere
Only stand-by LED’s from dew control and power distribution box	0.03A
Switch on the EQ8	0.47A
Siderial rate on	0.50A
Slew at rate 9 in RA	2.05A
Slew at rate 9 in Declination	2.00 A
Combined RA and Decl slew at rate 9	3.15A
Slew at rate 7 in RA	1.7A
Slew at rate 7 in Declination	1.7A
Slew at rate 3 in RA	0.55A
Slew at rate 3 in Declination	0.55A
EQ8 at siderial rate and dewcollar full charge of the C11	1.9A
Only Dewcollar C11	1.42A
Dew collar APO120mm only	1.10A
Small dew collar for guiding scope 50mm	0.52A
EQ8 siderial rate + dew collar APO	2.04A
idem + slew in declination rate 9	3.44A
above + slew in RA rate 9 (as well as decl)	4.6A	Converter overloaded, halted
ASI184MM Pro cooler at 94%	1.9A
above + EQ8 Siderial	2.24A
above + slew in RA Decl rate 9	3.9A	Converter overloaded, halted
