![]() The ASIair is based on a Raspberry Pi computer. Guide scopes and guide-cameras are not very expensive and need not be top-end equipment. This allows it to correct the pointing accuracy of the mount while imaging to avoid stars drifting and getting elongated stars. it could be 5 minutes) the guide-camera is taking an exposure maybe every 3-4 seconds. ![]() While the main camera is taking a long exposure (e.g. In large long focal-length scopes, an off-axis guide adapter is often used (guide-camera shares the main optical tube used by the main imaging camera because the adapter has a tiny little "pick-off" mirror on the edge of the frame designed to bounce some light into the guide camera. The guide camera is usually installed on a guide-scope either piggy-backed on your main scope or using a side-by-side saddle. In addition to the mount, scope, and ASIair, you'll also need a primary imaging camera, and a guide-camera. Other accessories such as guide cameras, filter wheels, focusers, etc. They now support some 3rd party DSLR cameras by Canon or Nikon. Originally they ONLY supported ZWO cameras. They do support most any mount (since ZWO do not make mounts). This device mostly supports ZWO brand equipment. You can see the new "all sky" method here: You can watch a video of how the original polar alignment process works here: This is meant for users who have an obstruction blocking their view of the celestial pole. ![]() They call this the "all sky" polar alignment. The new mode lets you use a piece of sky that isn't near the celestial pole. and how far away it is from the true polar axis and has you correct the mount. Having done this, it now knows the center of the RA axis. It does this one last time (so 3 images in all). It rotates the mount in right-ascension, then takes another image and plate-solves that. It uses the camera to capture an image of the sky and plate-solves to determine the coordinates. I'm not sure, but I think has some experience about ways to do polar alignment by plate solving, and without blowing the budget.ĪSIair can do polar alignment. If you know of other combos any ideas are welcome. I value the experience I find here, so I am asking questions. And btw, this is not something we are doing overnight, We know it is expensive, and we plan to get probably get a mount one month, a refractor the next, then start on peripherals down the road, we are looking at maybe $1000 to $1500 per incident. I have found some mentions here, and now I am curious, can the ASIAIR actually be used for the alignment process, or do you still need to use IPOLAR? Any thoughts appreciated. Angel suggested a ZWO ASIAIR PLUS, so we are researching that. I talked to OPT support, very nice people, and asked about hooking this up to a laptop to visually see what the scope does. One of the problems Emma and I both have is we don’t get around too well, and we have seen the horror stories of polar alignment, so again we try to research, and see the the IOPTRON mounts have IPOLAR that lets us align without having to be contortionists. This starts with a good solid equatorial mount, and we have been looking at the IOPTRON CEM 26 and 28. In the meantime we have been looking at refractors for a way to look at and possibly photograph DSOs. So now we are waiting for August to be able to see Saturn and others. Application communicates over INDIGO protocol and it can be used to integrate with any INDIGO/INDI 3rd party tool as well.Ok, Emma and I jumped in and bought a 150 MAK GOTO, we did a lot is research and love the scope, and knew it would be better suited for planetary views. EQDir compatible mount controlled over EQMac.īut it can be used as a client to any remote or local INDIGO or INDI server with any supported cameras and mounts as well.Īpplication can be used separately, but it is integrated with AstroImager (it can initiate random kick to allow dithering and suspend guiding during image download) and AstroTelescope (guiding is automatically stopped, if telescope is slewed or parked). NexStar compatible mount (Celestron, Skywatcher, Orion, etc.) Meade DSI camera (experimental code only) QHY camera (QHY SDK 1.1.0, experimental code only) USB or firewire IIDC compatible camera (including AtikGP) Starlight Xpress camera (all USB 2.0 cameras) In this version the built-in INDIGO drivers support the following hardware: It can be calibrated semi-automatically or manually, you do not need to take care about camera orientation or pixel scale. AstroGuider is a simple to use guiding application for your guider camera and telescope mount.
