Howie, I was impressed by your description of the rig by your mate from the club a couple of months back and put together an AZ GTe-EQ of my own. Must admit ,I was a bit put off by the feel of the AZ-GTI in that tilted position and didnt quite finish and have never used it, so I am not in a position to comment yet. All I have to do is attach the losmandy to the EVO 50 and I'm done. So,your post has spurred me on to at least have it ready to go. They are impressive images. I still think the ASIair for us VA'ers is for the single exposures only. That is all you can view on screen at any time. To stack, you have to wait until you are back home on the computer and your favorite AP programs. ....and, to be honest, until ASIair can live stack I will probably keep my little get up and go AZ-GTI setup in the alt/az.
cheers Paul

Yeah it isn't VA but is AP, but shows Tony's latest version of his AZ Gti operating in EQ mode rig. Out last Saturday night for end of year Christmas do with the astro club. Very bad smoke haze and very windy. I could not use my 8" Newt at all. Bouncing all over the place. Mate Tony setup his lightweight AZ GTi with it's latest addition ... no longer using the ED72 and its corrector. Sold it and replaced with Samyang 135mm f/2 lens plus adapter to attach to ASI1600MC. His adapter has a single filter drawer to avoid having to undo it all when changing filters. In his words ... $AUD 400 for an ED glass, fully corrected, very sharp refractor of extremely fast f/2 ratio plus a $AUD 300 filter drawer/adapter ... bargain! Imagine the cost to achieve that with normal astro refractors and such! His lightweight rig is in the photo below, along with a widefield taken with it. It was so windy even with his low wind resistence rig he had to shoot at 2 minute subs instead of his usual 5 minute subs with this rig. It's his usual one hours worth of subs ... like I said he does AP not VA. Just showing the rigs potential for VA and how portable it is ... and the idea of fast optics and such. ps. Both guide and main camera are ZWO's ... so imagine this with ASIAIR hanging off the AZ GTi. You could pack up the whole rig from the tripod up all assembled and cabled up ready to go. Plonk down the tripod, screw on the fully assembled mount and lens etc and you are good to go! Tap ASIAIR on your tablet and tap its icon to polar align and immediately start tapping on its object selection icon ... just blast off to targets using the ASIAIR platesolve and auto corrected GoTo feature to land on all targets! Up and running in a couple of minutes! Sweeeet. ps for some reason the forum photo upload would not let me upload Tony's original 20Mp image. I used photogallery to downsize it and the image below is barely half a Mp before it finally loaded. No idea why it did this? So at half Mp it's a bit pixellated. The original 20Mp is not. You could zoom in heaps on the orig image to see orion and the horsie up close and there was enough resolution for it to still look great when zoomed heavily. Turned his cheap rig into kind of a zoom telescope! LOL

cheers Paul BTW Paul .... re the current ASIAIR not stacking and only showing single frame on screen. A bloke who I sat down with for the entire evening has used the ASIAIR since it came out. Anyway, one other thing he mentioned to me was that he knows a bloke who is not doing full AP but a subset of full AP whereby he tries to get the best detailed image in single shots. He is guiding in order to get that, but importantly shooting low Unity Gain for 10+ minutes ... and ... tada .... the single frame auto stretch with the current ASIAIR is apparently very, very good looking! My ears pricked up when he told me this. I immediately wondered what such a single low gain but long shot would look like using just the AIR's autoexpand on the single frames? And of course, then experiment a bit upping gain to go shorter and so on until (maybe) arriving at a single frame of short enough duration to be within my/our short (VA) attention span ... but still long enough and of enough gain to see good detail without stacking.

Howie, thats how I think the ASIair should be used for VA at present... single exposures. I have never attempted anything over a minute let alone 10 minutes I dont have the confidence that my AZ-GTi can handle that long . Tim's results are impressive. I know that I couldnt do that and havent even given it a go. Instead, I have a EQM35 and an esprit 80 which should give me a minute or maybe 2 with the ASIair . I am down the Victorian coast with that setup . Unfortunately Thor is playing funny buggers with me and gives me clear skies long enough to trick me into setting everything up ,then rolls the clouds in. It looks like cloudy weather for the week . cheers Paul
