Discovery 150i WiFi - why does it need a red dot finder?

[Old Clive]

Hello

I'm still awaiting delivery of my first telescope, a Sky-Watcher Star Discovery 150i WiFi. So, without any user experience, I have this question (and apologies in advance if it's a ridiculous question!):

If, as described in the FLO website, all I need to do to find objects is enter the detail of my location into the GoTo app, why's is a red dot finder provided? Would I ever need to use it?

Maybe the finder is provided as standard on the tube and it's easier to leave it there rather than manufacture a separate tube without it for GoTo use?

Thanks

Hey Clive. There are no silly questions here 😊

You will need to use the red dot finder to make sure the scope is aligned properly when using goto. Goto will aim to get you to the right target but initially you will need to make sure it is aligning accurately. This will be explained in the instructions but there is plenty to read here if you search on ‘star alignment’. You will also need to make sure the scope is centred on where the red dot points - this is easily done in daytime using a terrestrial target - you basically find something in your scope (lampposts or chimneys are good) and then adjust the red dot to be pointing to whatever is centred in your scope.

Hope this all makes sense. Enjoy it and clear skies.

Thanks Dan, yes that makes perfect sense! And thanks for keeping your reply simple 🙂

Can't wait to get my telescope and start observing!
