Top 5 tips for improving planetary views with your telescope
About | Information | History | Online | Facts | Discovery
In this video Robert gives you our top five tips to coax the best possible views of planets regardless of the cost or quality of your telescope. It doesn't matter if your telescope costs tens, or thousands : it always makes sense to try to get the best views you possibly can when observing planets. And sometimes improving the view involves no more than selecting the best site available to you to set up the telescope or using the telescope within its ideal power range -- this video will give you the information you need to consistently get the best views of planets with your telescope.

I hate clouds

thanx for not making it simple , to get started. going to do this now!!
-
Is 200x good enough to see planets because I don't see them
-
Would 140 magnification be a good power?its within my telescopes resolution
-
excellent THANK YOU!!! I have been observing Jupiter at the wrong angle for days wonder WTH is wrong with my 10 inch Dob,. what a relief to know its not my scope.... it the operator. lol

I'm really enjoying this channel. Makes me feel a bit at home too as I lived in Norwich for a couple of years! Thanks a lot, will keep on following.

Good point elaborated.

Helpful info. If I might add some interesting advice: The Roth Formula is also useful for lunar-planetary observing: Get the telescope's aperture in inches, then find its square root, then multiply by 140. For example: for an 8" scope: 8√ (square root of 8 is 2.828), 2.828 multiplied by 140 is 395.98 or 396 power, the best magnification through an 8" for observing the Moon and planets which translates as observing with a 3-4mm eyepiece with long eye-relief. My long-focus 5" refractor that cools down very quickly with a motor drive which keeps the Moon or planet centred is so much better for lunar-planetary/ high-power observing than my 8" Skywatcher Dobsonian with its hot slow-cooling mirror that blurs and the constant, annoying, nudging to keep centring the object (though you can convert the tube onto a EQ-5 equatorial mount). The unobstructed aperture of the refractor is much sharper. Clear skies! Andrew

Excellent video, one of the best I've seen, understandable, concise and hits the main points for planetary viewing.

A huge thank you one of the best video's I have ever seen Brian

Very good Thank you.

Wonderful! Thank you!

Great help. So really then I have a 70mm Celestron so I take it that has a maximum magnification power of 140x.
It has a focal length of 400mm. I was using it with a 3x Barlow and a 20mm eyepiece (looking at Jupiter). By the math I understand to get magnification I do
(400x3)/20= 120x magnification.
I'm still within my scope's range. If I was to use a 10mm eyepiece and pushed it to 140x magnification, that's me on my scopes limit right?
I noticed when I put my 4mm eyepiece on I couldn't see anything, even though I was certain Jupiter was centred in my shot. I assumed it was because I was zoomed TOO far into Jupiter, but it's equally possible that shoving 350x down my scope's throat it just couldn't handle it right?
Also, even at 120x I couldn't get any proper focus on it. I'm guessing it's just because my scope can't focus like that.
Either way, seeing Jupiter was incredible. I hope I can see Saturn's ring in May with it. -
Very helpful, thanks.
