Sharpcap default to SER video files when using very short exposures. It goes back to Fits or tif or png when exposures are greater than 1sec. Also, you can change the file type in Sharpcap itself (turn off the auto button) or you can set the default file type in the sharpcap settings. Neil

12 luminance subs 11 bad pixels 10 (k)nights with clouds 9 RGB frames 8 amps of power 7 planets shining 6 wavelets altered a 5 position filter wheel 4 narrowband filters 3 element Triplet 2 stars binary 1 Crab Nebula glowing in the sky Actually just a ZWO ASI 533 - there has been so much bad weather I didn't think I'd make it any worse

to me, it looks like Registax is not Debayering the image - set debayering to RGGB before stacking - or you're not capturing in the correct video format - either RAW or RGB24 - preferably RAW

+1 for Steve - did a lovely job on myC11

Can you post the list here please - was also thinking of the same thing Thanks in advance Neil

And for a beginner I would recommend a GoTo and some additional software to do plate solving - learning to star hop, with such a restricted field of view and by the look of it, non-optimal skies- is a very quick way to put off a beginner as they 'can never find anything' (Cue debate on GoTo) Neil

And a full moon ?

Aaahhhh, that explains the hailstones ?

Or post your question at forums.sharpcap.co.uk

SWMBO will be in bed by 10pm - that should give me a couple of hours at least

I've got a couple of these on my SCT &Apo. I was under the impression that they were for SCT's and refractors only. The guys at Pegasus are extremely helpful, so just use email or their online chat to check with them directly. Neil

I've got the Pegasus Focuscube - which is a newer version just has all the electronics in one place (one on my C11 and another on my 127mm APO), - take a look here: http://astro58.wixsite.com/havenobservatory/focuscube Regards Neil

According to the Edge HD white paper, page 15, for the C11, optimal back focus distance is 146mm. See https://s3.amazonaws.com/celestron-site-support-files/support_files/edgehd_whitepaper_final.pdf. Neil
