I have recently acquired an AZ-EQ6 mount but am struggling to get decent GOTO accuracy so need some help/advice. On the plus side the mount is tracking fantastically - I have taken 4 minute unguided exposures with my DSLR and the stars are nice and round. I am using a refractor which has 1000mm focal length and I'm just using the hand controller with the skywatcher GPS attachment that sets the date and time. i.e. no PC software involved. I have disabled the auxiliary encoders as I don't need them and have heard they can be a source of problems. I polar align using the polarscope which I find plenty good enough to get good tracking accuracy. When I turn the unit on the GPS sets the date and time and I select daylight savings on and I have the unit in the home position so weights down and scope pointing parallel up towards the north pole (I've used the spirit level to set the setting circles so I can get the home position more accurate). I've tried 1, 2 and 3 star alignments but always have the same issue - it succeeds but then when I slew to another star (even a close one) it is a long way off (i.e. nowhere near being in view even in 30mm eyepiece). The oddest thing is that after centering the star and completing the alignment if I slew away to another star and then back to the alignment star it still points way off! In my mind I at least expected that to work - I thought it would just have some offset map between the calculated astronomical coordinates and where you've told it is really pointing so I don't understand at all how this can happen. Late last night for example I did a 1 star align on Vega and then told it to go to Deneb and had to move with the hand controller the end of the scope up a good foot to find it! It's like its completely ignoring the alignment adjustment I have to make each time to find the star so any initial error never gets corrected. Any ideas?
Hi I have just purchased the Skywatcher Alt Az GTi mount from FLO mainly because of its built in wireless control and weight and more importantly its portability for possible holiday use. Due to the usual amount of cloud and rain at this time have only managed to set it up indoors. It looks like when doing an alignment the mount slews the altitude and you are then left to slew the azimuth which is ok as far as I am concerned. The PC 'app' is a bit buggy but the IOS app works fine and I managed to get Skysafari working as well. My main question is this: can anyone tell me why I cannot find this product on the Skywatcher website Is it really that new? It seems reasonable quality especially for the price and I intend to use it with my Atik infinity for EAA so tracking accuracy is not paramount. I am loading it with a tec n sky 65mm apo refractor which is roughly one and half kilo's but I think it takes up to five so there are possibilities of a small SCT or larger refractor being supported. Would love to know what any others are using with it and any good / bad experiences? Cheers Williamnohair (Bill)
Hi, How accurate does your location need to be when setting up GOTOs? As an example, by default, the Celestron StarSense offers location by City. Where I am, three cities are listed, one about 150miles away, the other tow are both 20 miles and 30 miles away. Is that sort of error in location actually usable? Yes, I know that I can set a custom location on the StarSense Question is around how accurate to I need to be? Google, OS, SkySafari, SkyPortal, Astro Locator all give different locations, as do many other sites that 'locate' me. Thanks
