I have a 10" Skywatcher dob on a Synscan GOTO mount. I usually do a two star alignment, using a 2" 32mm GSO Wide Field eyepiece on a 2" Barlow., this helps to locate the first star. The mount then slews to the second star of choice, usually a bit out of alignment but no biggie to line it up. I get the Alignment Successful from the handset as usual.
Then, for example, if I decide to take a peek at Saturn, slew to the object, I always find it is not centered. Now if I was using a 10mm eyepiece, it wouldn't even be in the field of view.
The base has been modded with three adjustable screw legs, so I can get the base perfectly level, the location and the height is accurate, as is the time.
I have tried using the PAE function in the Utility Menu, on selection it knows what I'm looking at, as it asks to centre Saturn, which I do using the direction keys and then entering that data into the handset.
So, moving right along and selecting a new object, such as Centaurus A, I find it is not in the field of view. This is frustrating and I'm really not sure what, if anything I am actually doing wrong.
So, my question is, would a reticle eyepiece be useful for centering on alignment, what focal length is recommended as there are many to choose from, and or, is there a fault in how I am performing the alignment in the first instance?
I have a good quality power pack so a faulty power supply is not the issue here.
Any thought and advice is appreciated, Thanks. M.
