Re: Jupiter appears like white spotty LED traffic lamp on my dobsonian

You must be doing something wrong. Are you in correct focus or way out of focus ? Are you using the right eyepiece? Start with a longer one like 40mm, once Jupiter is centred, switch to your 10-30mm. Then rotate down from 30mm to 10mm,

Re: Jupiter appears like white spotty LED traffic lamp on my dobsonian

How did you collimate it? A large object like the moon is extremely forgiving for bad collimation.
Did you choose a star to do your collimation ? Do watch the youtube videos that provide tutorials on how to do it.

Thanks hhzhang. Seems like not much action 1 deg above the equator. Hopefully by 2023 normalcy will return. :)

Re: My astrophotography 2021

Good attempt, hhzhang. Some did manage to capture good photos after the eclipse was over but it depends on where you were because of the clouds. :)
