new telescope xlt 150

[Jarrod]

glad you're happy with your telescpe.

the lack of perfect focus may be because your telescope needs to be collimated, although at high magnifications alot of air movement will make sharp focus impossible.

jupiter appear's about the width of saturns rings.

for this scope...

sorry again

Bintel are in Camberwell and can sell you a collimation cheshire combo tool which will see you right. Please dont get sucked into a buying a laser tool.

Why the anti-laser suggestion Geoff? I use one myself and they seem to do the job just fine - not overpriced either ! I'm just interested to hear why you appear not to go for them

Cheers,

• A cheshire/sight tube combo tool in conjunction with an accurately placed mirror centre spot is everything you need to properly collimate a newtonian.
  
• A laser is of no use in aligning the secondary under the focuser - The sight tube is.
• A laser without perfect collimation of itself (by default cheap ones are out of whack) will introduce errors
• Error in aligning the secondary compounds as you adjust the primary to compensate - The combo tool facilitates both independantly.

People who arent aware of the above might inadvertently believe that the high tech solution must be the better one.

using a laser when im so new to this.. thanks m8

Congrats on finding and seeing the Rings of Saturn. It's one of those breath taking moments you'll never forget.

Also, about the collimation, don't forget you can check it by doing a 'star test'. I think you'll find the procedure in your telescopes manual under the heading 'Night Time Star Collimating'.

i have done that it seems very good maybe a hair off the centre
i just think it will be needed i have 4 kids i see my tripod being knocked around

and i will most likely travel to a darker place once i can talk my wife into
being my taxi...lol

so best to have it on hand i think...
