With reference to my previous post regarding alignment accuracy I mentioned that I had contacted Celestron themselves for feedback. They have replied albeit without commenting on my real query which was to do with the time taken to do a slow motion adjustment at the end of a slew... however what information I have received has somewhat surprised me and I thought worth repeating here. Celestron mentioned whether I had "started at the index point", to which I replied I did not know what an "index point" was! The reply came: The index mark is a starting position for alignment. On the SLT it's not clearly marked, but it's when the optical tube is pointed at the horizon, so the telescope is flat and parallel with the ground. Each time you align the telescope, start from this position. This is a step that's often overlooked but is essential for a successful alignment. ...in addition, they go on to say: With each star (..you align to), you want to center it in the finder scope and press enter. Then, you'll notice the scope moves much slower. This is so you can center the star in the eyepiece. First, use a low powered eyepiece like a 25mm to center the star. If you want to be precise, you can then remove the 25mm, and place a higher powered eyepiece like a 10mm, and then re-center the star. When the star is centered to your liking, press ALIGN to lock on. Make sure you repeat this step for each of the 3 alignment stars. So to summarize.. I did not know that leveling the scope was as essential as leveling the tripod (why is it not highlighted in the manual I wonder!), and in addition I had missed the significance of having the scope slow down when you press ENTER on the HC. I assume both of these things will significantly aid accurate alignment, but have yet to test them out. I am still non the wiser about the slow-mo adjustment time taken by the scope which occurs after ALIGN is pressed, but the fact that they did not mention the time involved I can only presume means there is nothing unusual in the scope taking 30 seconds or more to finally stop and get a fix. I am still going to time this precisely at some point but again, I have not been able to yet. Hope the information will help others working on improving their GOTO alignment accuracy SkySpy
