Devils Mask - Updated with more data

Hi

Attached are a couple of images of the interacting galaxy triplet of NGC 6769-71.

One shows a full frame image at 25% full size, whilst the other is a 20% frame crop at 50% full size.

Less compressed version is here:

300min total exposure taken over the past few nights from my obs in Melbourne through a GSO RC14 + ASI2600MC camera + EQ8.

Processed with Astro Pixel Processor.
Seeing was OK & varied between 1.9" and 2.6".
A nice little galaxy cluster is visible at the 7 o'clock position near the bottom of the full frame.
This could do with a great deal more exposure time, but given the appalling skies that we have has here for a while now - I'll take what I can get.

Comments welcome

Cheers
Maurice

I have added another 9hrs of data to this one.
Total is 14hrs now.

A 60% sized 20% crop can be seen here:
