So the little circular bubble level is weak. But how to improve the levelling stage a head of the alignment stage? A traditional level like this one Or a simple multi purpose one like this one? And we do this on the tripod before adding the mount & OTA? The mount looks gently curved. How do we check that for level or do we trust the ‘fit’?
I often read that leveling your mount is nonsense or a ‘myth’… Although it is not absolutely necessary to level a GEM to achieve good polar alignment, leveling is a very easy and handy way to make the first step into polar alignment, for the simple reason there is a relation between level and latitude. Latitude is always measured as a deviation from level, so why not start with level in the first place? When leveled you can use the marks on the mounts latitude adjustment scale to get a rough alignment together with azimuth adjustment. Yes, without leveling you can get polar alignment as well, but it is a lot harder, because there is nothing to start with… Especially when you cannot see Polaris at your favorite site, it is a good idea, to go to a site where you can see Polaris and prepare your mount for ‘blind’ pa, by leveling it as precise as you can, do a polar alignment as good as you can and leave the settings as they are for your next session at the ‘blind’ place. On that place point your mount roughly North with the tripod or azimuth adjuster and level again as precise as you can . Then slew to a star that you can see (preferably South) about the same latitude as Polaris. You will need to adjust azimuth to get it centered, and maybe a little tweak with latitude (because of ‘flaws’ in your bubble level), but it should be very close if you did a precise leveling... Simple one star polar alignment on a place where you cannot see Polaris! For imaging this alignment procedure together with the use of PHD will be (reasonably) ok as well.
Hi! I have just bought a heq5 pro and I have some questions... 1. Level. I have watched many astronomy videos and almost all of them uses a small level tool to level out all three legs on the mount. But on many mounts like the heq5 pro there is a built In bubble leveler.. Is it better to use a small level tool than the bubble? 2. Polar align. I have read and watched many polar align videos but I'm still insecure on how I should do it... The mount has a RA index scale, and a date circle. What I have understood is that those are for enter date and time to find Polaris, right? But do I have to use those scales if I use a polar finder app that tells me were to put Polaris in my polar scope? Like the photo below After this I should do 3 star alignment for more accurate tracking (I only have dslr to align with) right? 3. Home position. This is needed right? if so, how does it work and how do I do it?
