Quote:Hi, I just downloaded the manual from the Celestron site and was reading it. I noticed it said that if your imaging you might want to add calibration reference points to improve accuracy and so it will better center your objects. It said if your just entering one it should be near the object your imaging. Otherwise you can enter up to 10 calibration reference points. It also recommends adding multiple calibration reference points when doing a Polar Alignment. I will want to be adding about 4 calibration reference points each night. It wants you to manually slew to each reference point. This kind of takes away from the whole ideal of having an automatic alignment device. If I don't use the Starsense and manually align my mount, the mount will automatically pick and slew to each of the calibration stars for me. But not if I'm using the Starsense. I think its kind of crummy that I will have to manually slew to each calibration point I add. Plus I will have to decide where in the sky to slew to for each of these added cal. points. How am I supposed to know where the best places to pick are. I think they need to do a firmware update already. It sure would be nice if you could just input the number of additional calibration reference points you want to add. Then it would pick where to add them and automatically slew to each one. Geez it seems like common sense would have told them to do it this way. And if you want to just add one in a specific area then you could manually slew to that area.I'm guessing many of us plan to take some images and plan to use the Polar Alignment feature. It sure would be nice if this thing was Automatic on the added calibration points also, and not just on the initial alignment points. I'm not going to like having to manually slew my mount to points from one end of the sky to the other 4 times. And I have no ideal where the best places are that will do the best overall good to improve accuracy or for the Polar Alignment. I think Celestron needs to get back to work and come up with a firmware update to correct this.Neilson
Quote:There are no calibration stars.What there are is calibration positions. The SS takes an image and plate solves it to get an alignment point where it knows the axis position and sky position.There are two main align modes.In SS Auto the mount slews to four points, takes an image at each and uses the position to get an alignment. If it fails to get an image it can solve it moves a bit and tries again. It will keep doing this a lot until it has 4 points. This is for GEMs, there are two points on each side of the meridian. In AltAz mode I think it uses three positions.In SS Manual the user has to do the slewing to the positions. There's no need to move to any specific position, just a bit of sky that's clear. No need to look through the scope. Simplest is to do two positions on one side of the meridian, the two on the other.A calibration position can also be added by simply selecting align and Add Calibrate position. SS takes an image of what it can see, plate solves it and adds the position to the mount model.So if the object you are expecting isn't in the field add a cal position of what is. This will give a good position near what you are looking at and a subsequent move to it should be more accurate.Bear in mind that this does NOT use calibration stars. It uses the sky it is looking at and does a blind plate solve.Chris

Quote:2) Again, how good can SS alignment can be at 40mm F2 (so only 80mm FL), considering Meade Starlock has 2 cameras and 2 different FL objectives, one being a 80mm F5 scope (400mm FL)?

At 80mm focal length the resolution will be measured in arcseconds; that's plenty good enough for star alignment. If Meade used a longer FL scope for their star location, that would have no bearing on Celestron's system - but Meade does not. The 400mm focal length unit is the guidescope. Location is done via the widefield scope - which looks to be around 80mm long. It works fine for Meade (I have one) and should be just as good for Celestron.
