Neptune 1st Sep 2014

First rough attempt at Neptune.

Looking at the size on screen , the lack of anything to focus on or see and it barely showing up with gain at max and ms on warp drive 9 ...all just showing a tiny grey smudge cloud that wouldn't stay still. Tired and beaten I hung in for what I though was a waste of time at an impressive 0.8 to 1.5 fps on binned ( may be party due to my lap top not handling 1/1000 Ethernet gigabit ) .

Anyway it stacked and this is it. Disappointed at a lack of anything but it's a blob at least. Hope I can can something more accurate next time, and may try 2x instead and a faster connection.

Have increased size and cut .

C11 2.7x Barlow PG Black Fly about 3/400 per channel RGB. (IR was invisible and about 1 frame a week :-)

Good image, Simon. Sadly at Neptune's altitude and without an ADC you will find it extremely difficult to find any top layer cloud details at all on the disc. Besides it's neighbor Uranus Neptune is an extremely difficult beast to capture. Usually the consensus is anything between 300ms/500ms exposure, 1/5fps, maximum gain and using a 610/685nm longpass filter for anything up to 60 minutes or more. Neptune and Uranus both need a little practice but detail on very steady, clear nights are really achievable.

nice round disc and good image scale. i have seen a few images with surface detail, but its quite an achievement to capture any.

That has come out very good. Love to be

able to get something like that.2800 x 2.7

makes a f/l of 9.6.m.Impressive
