2nd Light, Esprit 120

My first light attempt was a complete disaster as I reverse connected the battery.

This blew up

1. Mount motherboard
2. Synscan Wifi unit
3. AsiAir pro power outputs

Luckily the cameras, focuser were not damaged. All up it cost me around $800 to rectify my mistake.

The AsiAir pro usb inputs are fine but I had to buy a pocket power micro to power everything.

The Esprit has a longer focal length of 840mm compared to my TV85 at around 450mm with reducer. This seems to let me take at least 300 sec exposures without any filters under bortle 9 skies and a 80% moon in central Sydney shooting away from the moon.

Anyway this was just a quick shakedown to test that everything was working.

NGC3372
20 by 300s plus darks, flats and bias
Esprit 120
ASI2600 MC
FL 840, supplied flattener
No filters
Processed in PixInsight

Unlike my TV85 the image is flat across the entire field, I only cropped a few pixels at the edge to remove the stacking artifacts.

I am not sure about the focus, maybe someone could comment on the focus?

Cheers
Paul
