Ok - Samta might look somewhat slimmer than all those Xmas pikkies suggest & I haven't seen him in his red outfit & cap but he still delivers..!
Thanks Sam, you're the Ace of Spades!!! ...John's images here on CN displayed the very nice appearance of these units, but holding one in my hands certainly confirms there manufacturing build quality - now to test their optical capabilities in the hands of this complete newbie..!
John's current long-running thread is one of the places to be if us rookies want to bone up http://www.cloudynig...-zwoptical-adc/ ...as is Martin's site also http://skyinspector....-corrector--adc along with other informative sites etc...
I've made this a separate thread just to bring more attention to the unit & also focus a bit more on how we might incorporate them into the image trains we use...
Fortunately I had all the where-alls to construct what I hope is a satisfactory assemblage...I could do with a very short spacer ring with a male T-thread on the outside...I do have one but I cut this on a lathe along with another one that accepts the TeleVue 2X barlow lens element...this meant that there are some "pecadilloes" to the thread & on some fittings/adaptors they don't work..!
Both screw into the ZWO ADC's female T-threads but NOT into the Nautilus EFW's female T-threads....!
I want to sort this out when the stores re-open after the New Year because then I can have an imaging train where all the elements are screwed together for greatest integrity/stability - atm I have a special adaptor I made up with a female T-thread which screws onto the back of the Nautilus EFW & has a 1&1/4" brass compression band clamp to accept the barlow element, ADC & camera.....a short male spacer T-thread will allow me to place the barlow element ahead of the EFW (ie, nearer the scope) & means slightly less primary-secondary mirror spacing for back-focus...as well as being an "all-screwed together" train...
Really looking forward to the next imaging opportunity - we only just got back from 2 days up North at Ororroo (a 900km round trip) but the seeing was rotten - "chasing the seeing" isn't all fun & games tbh..!
Here's a couple of piks of how the unit will look if we head off again before we get that male T-thread spacer...in this configuration we have 64mm distance between barlow element & camera sensor - there is normally 76mm separation from element to the top lip of the TV 2X barlow so we should get a bit less that 2X...probably around f20 which I'd be more comfortable at than the current f22+ we employ without the ADC on the ASI224MC - so that's an added bonus!
DISREGARD THE "ASI174MM" ON THE CAMERA - THIS IS A "BETA" ASI224MC IN A 174 MONO BODY..! - also, only phone piks...my camera's card-reader is stuffed!
