WOW I never get anyting even close to that.
I must be doing something wrong.

Great post though. It has inspired me to collimate my scope alot better he he he.

Great site

I have had comparable views of Jupiter and Mars with my 6mm ep and 2x barlow on rare occasions when the seeing has been excellent and plants near, or on meridian.

It's pretty rare that seeing is good enough for me to use 240x mag with my current setup tho'. I find my 6mm ep with my f5.3 reflector (133x) give pretty good results with the planets, the images are small but very clear.

One day I might be able to afford a high quality short fl ep

My scope must be pretty bad if thats what your ment to see..
Good site though.

I don't know what's going on! My Joop looks like their Joop but my Saturn never looked like their Saturn! My Saturn is in between their two versions on good seeing nights.

Hmmmm, not good. To my untrained eye, my views look like the 5" scope or less on the moderate seeing nights. I have a 10" dob.

Thiink · #7 22-07-2005, 04:02 PM

Same with me MiG. Actually this ties in with the post I made a while ago about my views of Jupiter. Actually I am going to have to have a look at my secondary this weekend, I havent got around to it yet.

His light pollution pages are interesting too. If only local councils would change all the street lights over to more efficient ones.

Sorry! But I find that VERY difficult to believe it's anywhere CLOSE as a representation as seen threw a scope. I'm dismissing it as typical internet crap..

If newbie's are going to relate that with there first view threw a brand new 12" scope....Their either going to get the axe out or send the scope back! lol!
Iv'e never seen view's like that threw any scope..with perfect seeing or not....perfectly collimated or not. The only way your going to get those views is if you get rid of earths atmosphere. Hey, no offence vindictive, it's 'interesting' none-the-less mate!

ving (David) · #9 22-07-2005, 06:04 PM

i have had comparable views of jupiter (good seeing) but saturn well... my detail has been good but not like that, prolly more like the 4" or 6" in detail but maybe not quite as clear. i prolly just need good seeing.
havent seen mars in my 8" yet
looking forward to it.

Well I'll throw a cat amongst the pigeons here as far as Joop is concerned I think it's pretty accurate. The last night at Wiruna this year (Sunday). Dark skies near perfect seeing, I reckon he's got it pretty spot on.

davidpretorius · #11 22-07-2005, 06:48 PM

great stuff, something to aim for. I am very happy i have gone for the 10"

ving (David) · #12 22-07-2005, 06:51 PM

and you sound it too dave!

jjjnettie (Jeanette) · #13 22-07-2005, 09:47 PM

The images of Jupiter and Saturn are pretty accurate for the 60mm scope, but Mars is no where near that good for me.
Maybe we need to look through the eyepiece a bit harder. The more you look, the more you see.
Anyway, how often do you get perfect seeing?

asimov (John) · #14 22-07-2005, 10:16 PM

4 time's a year roughly, for me here in SA..

RAJAH235 · #15 22-07-2005, 11:10 PM

I get images comparable to those. I think they're a fair representation of what I see. On very good nights, I've been able to go to over 300 x on Jupiter & Saturn.. with similar results.

I definitely get better views of Jup's through my 8" on a good night. Actually their good night is more like my medicore night. Never been able to pull Saturn out of the sky with my 60mm like that site shows. Mars is debatable haven't seen it at it's closest approach, didn't have a scope in 2003 when Mars was about. The colour looks all wrong as far as I can see, maybe it's time to take the sunnies off when I observe

anyways that's my take, I've seen this site somewhere else sometime ago.
It almost looks like a direct copy of it.

Well I'll jump on the same wagon with John,Laurie and Rob. Anyone thats not seeing good views should reassess their equipment. Whether its collimation,pinched optics ,eps or whatever. I dont think I could accept viewing with anything less than I'm used to. With good seeing (not excellent) I can magnify to around 400x no probs.Thats my viewing limit, but only because I dont have a good ep to go above that ,that will still give me a crisp clear view.
Soggy blobs I'm afraid just dont cut it with me.

Try this link and refer to the planetary pics at the bottom and especially the closing statement.

Thierry Legault - The collimation

The whole article is brilliant and well worth reading by any reflector owner inc SCTs.
Why settle for anything less than whats acheivable

davidpretorius · #18 23-07-2005, 02:49 PM

another great collimation tool!

slice of heaven · #19 23-07-2005, 03:12 PM

Maybe not so much of a tool Dave as more of an eyeopener to some.
I strongly believe that extracting the most out of what you have is important.

davidpretorius · #20 23-07-2005, 03:51 PM

exactly
