    Zwo asi 1600mmc Help!

    I use RAW16 for DSO when stacking a smallish number of longer exposures and RAW8 for planetary/lunar/solar when stacking 100s if not 1000s of frames of very short exposure. In fact I use the 'Brain' function of Sharpcap to tell me when it is advantageous to use RAW16. Neil
  2. Being mainly an SCT man, longest I owned was probably the 8" f/6 Dark Star Newt,longest used = deffo the 18"/24" Radcliffe twin refractor at eh University of London, Mill Hill when I was doing my degree - http://www.ulo.ucl.ac.uk/telescopes/radcliffe/ Neil

    Settings for ZWO ASI1600M

    ZWO removed the ability to alter the offset ( what used to be brightness in earlier versions of Sharpcap) in the latest version of their drivers - which is why its missing in the latest version of Sharpcap.

    Nice work Charl. I finally managed to get out today for first time in ages - hope to get processing done tomorrow.

    sharpcap capture settings

    IIRC if you capture in RGB24 then it should playback in colour. If you capture in Raw8 or Raw16 then the video file will need to be debayered - with something like PiPP - I think the debayer setting is RGGB. Neil

    Very sad news. He was a great inspiration to me when I began webcam and video cam imaging at the start of this century. Neil
  8. those errors generally mean a power issue but the alt axis bolt may also have become too loose, so worth checking and tightening. and worth checking this out:- https://www.celestron.com/blogs/knowledgebase/what-does-the-hand-control-message-no-response-16-and-or-no-response-17-mean Neil

    Quark advice

    Good point, well made. on my 127mm Apo I needed an extra 60mm 2" extension tube Neil

    Quark advice

    I've used the Baader on both my 102mm & 127mm refractors with no problems. I would strongly advise against a generic/no-name uv/ir cut filter - the first one I tried cracked inside 5 minutes - fortunately - no damage done. Neil

    Finderscope mounting

    How about using something like a Celestron Travelscope 70? Neil
  12. Huw, Just like you my original scope was a C11 on its forks and then, later, on a Milburn wedge. This was housed in a Pulsar 2.1m dome. The C11 is now on a an EQ8 and - yes it does fit. Some of the clearances to the walls are a little tighter, but that might just be due to the fact the the C11 is dual mounted with a 127mm f7.5 Apo refractor . At the mo, I'm only doing unguided exposures - up to 20 secs on the C11 and an ASI 1600MM-Cool @f10 and/or f6.3 with no trailing. Guiding is my next challenge to overcome before the winter

    Meade F/3.3 reducer

    I have a 'made in China' Meade Series 4000 f3.3 reducer, with all its bits - 15mm space, 30mm spacer, T adapter and a 1.25 adapter - and a photocopy of the instructions. Pics available if interested. Neil

    Synscan and the 'Home" setting

    Apologies - I was confusing the OPs NEQ6 with the other mounts mentioned - i;m still sure the the NEQ6 does not have dual encoders and therefore cannot be moved by hand and have the syscan handset know where it is. @cornelius - excuse me if I have got this wrong, but the EQ6 (and therefore I assume the NEQ6) manual, page 9 last paragraph states:- (I paraphrase) (Sysncan Only) - don't move the mount manually, or you will have to re-home the scope and redo the star alignment). And i think I see where the confusion occurs - in 'Easy Tracking' Mode, yes you can move the scope manually, but only manually to one or more objects - the hand controller will not know where the scope is actually pointing and so cannot be used for Goto - each object to be observed has to be found manually - but you can use the up/down/left/right keys to move the csope. To use the goto function of synscan, you must perform a full feature initialization. I'm still guessing but I think the OP begins in 'easy tracking mode' moves the mount manually to the object and later tried to use the handset to move to other objects?

    Synscan and the 'Home" setting

    Thanks for that - good to know - I've not follwoed the skywatcher mounts developments. Makes my process a bit obsolete. Neil
