Skywatcher Skyliner 150p Advice Please.


Recommended Posts

Can anyone recommend some EP's that would come in very useful for a Skywatcher Skyliner 150p that I have preorderd  from Jessops ( they hope to have one for me for nest week).

http://www.jessops.c...89958/show.html

I am a total newbie who can not get his head round the maths of determining how to work out what might be best  (if anyone can help me understand this)  :embarrassed: . I am on a very limited budget so any good advice would be very much appreciated, as I would like to have a few ready for my scope arriving next week.

Also any advice about filters etc.

Check out TeleVue Type 6 eye pieces... they're awesome.

They are awesome, no doubt.. but will destroy a limited budget..

I think best quick advice is to give the 25mm ago that will come with the scope, so maybe if you need to, replace the 10mm. I suspect most would suggest the BST starguiders.. seem to get a lot of good complements

To work out the mag which you will achieve with a given eyepiece you simply divide the focal length of the scope (yours is 750 I believe) with thw focal length of the eyepiece.

So a 10mm eyepiece will give you 750/10 = 75x mag.

The scope will come with a 25mm and a 10mm no doubt.

I would recommend that you get a 2x barlow. This will double the focal length of the scope (1500) so the 10mm will now give you 150x mag.

Please note high mag is not always best and it takes time to get used to viewing the skies with a scooe.

My advice... save your money. Buy a 2x barlow and learn... slowly.

Can you recommend a decent Barlow?

Stay first with the 25mm and 10mm.

Now. +1 for me its a barlow. And im following the opinion that you have to buy a solid one because it will be forever a partner to your nights...Tele vue powermate 2x or 2,5x. Start from that

A very good thread which is worth reading is this one: http://stargazerslounge.com/topic/43171-eyepieces-the-very-least-you-need/

Particularly if you cannot spend too much, I suggest you the second hand market. A very good website is:

http://www.astrobuysell.com/uk/search.php

You could also consider Vixen SLV, but there are other options of course and I am not an expert on eyepieces. 

Said this, I would advice to consider the focal lengths you might need before the brand to buy. 

If I were in your position, I would possibly want something like:

32mm, 16mm + powermate 2.5x

or 

32mm, 12mm, 6 or 7mm

In ANY CASE, buy or update gradually.

As mentioned above, use for a while the eyepieces that you received with your telescope just to get some experience.

Good luck!

Good advice to stick with the EPs that come with the scope for a while. I have the same model of scope and I think you'll find the 10mm is the least impressive. The 25mm is more satisfying.

I won't attempt to advise on or recommend a brand of EP because I'm not experienced enough. But, as above, the BSTs seem to be highly regarded.

Just a quick point, though, your scope has a focal length of 1200mm, not 750. There is another Skywatcher with a similar model name which has a focal length of 750 (I think the P, for Parabolic, is all that defines the difference) but, as in the ad you linked, yours will be 1200mm. The sums remain the same: divide the focal length (fl) of the scope by the fl of the EP and you'll get the magnification number.

It will be well worth your while to read up in books or online about what is sensible magnification for your scope and your situation - light pollution, etc - before spending any money on EPs or Barlows. Most definitely do not think that the higher the magnification the better. That is NOT the case.

Also, have a look at the used market if you're on a tight budget. And bear in mind (even if I haven't!) that the great Al Nagler, of Televue fame, reckons that you really only need three EPs ...

Most important, of all - have fun with your new scope. Looking forward to seeing you around SGL.

EDIT: Largely beaten to it again! The joy of SGL ...

The 150P is F-1200mm so 1200/10=120

pipped at 1107?

.....My friend is a little modest on recommendations...he has a fine premium set of eyepieces for that scope. I on the other hand,  favoured the budget, end of the spectrum, but still,  great eyepieces no less, for your first upgrade,

Hello all new guest here.

Never before used a telescope always binoculars mainly for moon observing so decided to take the plunge and buy a telescope.

Bought a celesteron astromaster 114 off eBay, pointed it skywards and can see absolutely nothing and yes I had removed the lens and eyepiece caps !! Anyone give me a basic idea as to what I am doing wrong or direct me to a shop in the Manchester area ? We

Used to have a telescope shop here in Stockport but it has now closed and gone online.

Hope someone can help or I will be back to binoculars.

Many thanks. Jim

Not tried WEX myself but have you considered FLO (link at the top of the forum).

1st class and usually price match others.

Thanks but contacted FLO this morning they could not match Jessops and were slightly more expensive than Wex for delivery.

Jessops £175 and free delivery isn't too bad. You'd  get a 1 Year warranty, and if you can collect from the store, take it right back if there any are issues. All the help you need would be here if you ask.

Remember, the Newtonian Dob requires tuning  ( collimation from time to time ) Not sure Jessops will help you there much, but not finding the scope any cheaper elsewhere, does not leave you many options?

Charic, I have gone with  Wex. I hope I have done the right thing.............

Can't "tell" you that. It might, it might not.

Get it assembled and use it; enjoy yourself; have fun checking the collimation (more reading) and, if necessary, collimate.

I know you're excited and trying to do everything at once but take it easy ...

Repeat: have fun.

I have the same scope, it did need collimating when I got it, but i found it a very easy scope to collimate, however I had done this before on my other scope.

I have added just 2 eyepieces on the recommendations from the astronomers on this site, they are 15mm & 5mm Plossl's, great eyepieces, the 15mm never leaves the scope except when looking at the planets when the 5mm takes over.  I replaced the standard Barlow with a better quality one, and it made a big difference.

Hope this helps.

Jimbo, looks like your post got overlooked, try putting the lowest power ep in the focuser, this should be a 25mm, DONT use the barlow if it came with one, then point the scope at the most distant object you can see and slowly move the focuser back or forward till the object is in focus, hope this helps

Having acquired a telescope, it's a sound idea to have a play with it in daylight - have you done this? Amongst other things it helps with lining up the finderscope with the view through the eyepiece.

Hope it works out.

PS there's an introductory section for introducing yourself to the community here. If you do that, your post won't get "lost" in the middle of another topic as this has done and you should then get more people leaping to your aid :blob10:
