60eq – I assume this is a 60mm aperture ? in which case the theoretical maximum magnification is 120x – F15 indicates the f length is 900mm, which means that you should not expect much from anything shorter than 7.5mm, and that is in the absolute best ideal conditions ! might be worth getting a plossl or two – longer f len eyepieces yield better eye relief, so use these with a barlow to extend the range.
The equatorial is useful in that you should only need to track in one axis.

Hi – google ‘The Jupiter seeing tutorial’ – the web page should be the first google reference. Scroll down the page and you will see images of jupiter through various aperture scopes form 60mm up under different seeing conditions
@sfedida Ok, thank you. The moon isn’t out here right now, but I will keep that in mind. What would you suggest for viewing planets? I could see Jupiter and tell it was Jupiter. I could see a faint line at the top of it which was some of the planet’s coloring. I would like to be able to see it in a more detailed fashion. I could see three of it’s moons off to the side. Will I need a different scope? Thanks.
Hi – a 4mm e/p with a 60mm F15 scope gives a magnification of 225x. This is huge for such a tiny scope. Stuffing it in a 3x barlow just makes it worse – you won’t see anything ! – image too dim and contrast too low even if the planet remains in the field of view.
You can test if your scope and e/p combo is working correctly by checking it out on the moon. The moon is so big and bright you can’t miss it. If it doesn’t work on the moon it won’t on the planets.

Ok, awesome video, but I have a question. I just bought a celestron powerseeker 60eq. Last night, I was able to view Jupiter and three of its moons. That was through a 25mm lense. I was able to attach the 3x barlow lense an still see it. But, whenever I try to use the 4mm lense by itself or with one of the two barlows, I cannot focus it. Is it common to not see these planets in a very detailed form? How can I view the surfaces clearly? Better telescope? Thanks
