It's out of collimation to the point that you can't get a good focus on the moon and planets. Doesn't have a serial number to register it on the web site, that requires it to be registered. Called for help and was told could register with the date?
We cannot guarantee collimation when a telescope is shipped. One drop and the mirrors can move. We will be happy to guide you through collimation. Go to our customer portal -- https://explorescientific.supportsync.com/ -- register an account, open a case, and tells us the support you need.
Regarding the serial number questions: Our product registration page -- https://explorescientific.com/apps/product-registration -- outlines the process.
It states: For products that do not include a serial number, use the product item number followed by the date of purchase expressed in a six-digit format. For example, a purchase date of January 1, 2018, would be entered as 010118.
Very good quality
I’m not sure as this is a Christmas present and wrapped upon arrival, which is taking a big chance that all is good given your 30 day return policy! Also I’ve tried to have my email address changed by contacting support, no response. I’m hoping the telescope is good and undamaged on Christmas morning.
