Its not perfect but I'm improving over last years image..so I'm happy.

Imaged from Brisbane with ASI1600mm

It is showing some nice contrast and colour Tony, should be happy with it :)

Nice! Dare I ask how much exposure time it needed?

Interesting to see the FOV isn’t wildly different with an object like this, compared to my Esprit 100.

Cheers mate, got to heaps to learn but getting there.



I have a focal reducer on my esprit 120 brings it down to F5.6 and 672mm
Total was 3 hours exposure time.

That looks pretty good Tony. Nice palette with good detail.

[Camelopardalis]

Nice - explains the similar FOV :D

Not really familiar with narrow band imaging but opening your image Tony it certainly has a "wow" factor, very nice indeed congrats :thumbsup:

Lookin' good, Tony. Stars in the center are nice, small and round. What exposure length were you using here?

[Striker]

Hi Lee,

HA was 5mins subs
SII was 10min subs
OII was 5mins subs

these times gives me approx. 900 - 1000 reading on SGP

I now have the right distance from flattener and reducer to sensor so my edges are far better now from testing all last night.

The above was not the right spacing distance, was approx. 3mm too far out.

Looks pretty good, Tony. Continual improvement is the name of the game!
