Always of interest.

Strangely, your images have a "live feed" feel about them which involves the viewer in a different way to the beautiful processed long exposure images.

How much processing time time went into these?

Thanks guys for your interest - glad you like the video - it was fun to make.  My YT Nytecam Channel started in 2009 and mostly astro, has had a  >million hits and a good way to promote astro to a wider audience  :grin:

Hi Paul - I work in relative darkness in obsy to avoid laptop screen light bouncing into scopes and fogging the camera.  Although the downloaded images look fine under these conditions they are too dim in normal room lighting next day so they get a contast boost and lightened eg may be a couple of minutes at most before posting here :cool:  

BTW - there's two remote and v faint gxs in the in the 90s [6x15s summed] N891 pic as arrowed below that the camera picked up - the one to right doesn't seem marked on my charts whilst the LH one is although much fainter is !

N404 shot, apart from bright star ghosts. shows sensor needs cleaning with over a dozen dust-bunnies :eek:

In a word - YES:-)

That's interesting because if the graininess were random noise, sum stacking should reduce it. On the other hand, if the graininess is a representation by an undersampling sensor of what is actually out there (or if it is a fixed graininess of the sensor, say), then sum stacking will preserve it... 

I may have missing something but that's my understanding.

This is something I hope the hybrid modes coming in a future version will help out with - the benefits of sum but then reducing noise by median combing the mini summed stacks. The downside is that you will need more exposures to get the full benefit. On some of the targets I have observed I sum stacked 5-8 exposures, so you would need around 20-32. The concern then is field rotation - but hopefully it just will be the edges of the image that look rubbish but then leave a nice result towards the middle!
