Some help here

[Amit]

I got 1145P today. But I need to step up the magnification. I am open to all sorts of options EPs Barlows etc.

These are the EPs available

Eyepiece | Super Plossl Eyepiece 1.25"OD

And good quality barlows

The colour corrected achromats are the ones that I plan to get.

2x is of antares the 3x one I have no idea.Please help me

You should first tell us what eyepieces you have. You may find that one or two extra eyepieces will do more for you than a barlow. Personally I've never owned a barlow: nothing wrong with them, I've just not so far seen the need for my purposes.

The 1145p is f4 telescope, with a paraboloid mirror.

It will deliver some super widefield views of the skies.

I wouldn't get too hung up on magnificaition though, I would suggest x250 as a maximum, but others may disagree on that. A lot will depend on your seeing conditions. It is a rich field scope at f4.

Build your Eyepiece and Barlow collection around 200x, perhaps a little more for really good nights. There are some noted eyepiece experts on SGL, and I would await their advice before committing your money.

Enjoy your new instrument Amit.

Hate to disagree but I would doubt you will get anything useful beyond 160x.

At (if) f4 then a 4mm eyepiece will give 114x.

There are not that many good 4mm eyepieces, except for a fair amount of money, you will need a good barlow to push the magnification, again cost.

I know that you can get a TMB at 3.2mm that makes 145x.

You can try barlows and eyepieces that will give on paper 200x but I seriously doubt you will actually see anything through the scope.

I wouldn't get to hung on the idea the more you magnify the more you see, there's a sweet spot for all scopes, your going to have to find yours, it certainly won't be above 200X the seeing condition just won't allow it...

[umadog]

160x equates to about 35x per inch in your telescope. This is considered "very high power": Useful Magnification Ranges for Visual Observimg - How To Unless you have very good optics it's unlikely you'll be pushing much beyond that. Perhaps you'll get to around 200x, but beyond that all bets are off.

I have the EPs that came with the scope ie super 10 and 20. I dont want to push the magnification beyond 160x, If i want 150x then 3x barlow+super 10 and if 166x then plossl 6+2x barlow. My only doubt is that are these barlows good enough to be used with the scope?

[Tribal-Wolf]

The 10mm that comes with Skywatcher scopes is not so good so you might want to invest in a better quality 10mm or maybe an 8mm and something like a Tal 2x barlow. With the scope collimated correctly that will be about your tops. You could also buy a decent wide fov EP too.

[Amit]

Actually the dealer in india doesnt keep tal barlow.

This is an antares 2x barlow achromat and colour corrected which is around 40 british pounds. The 3x barlow I have no idea and apochromatics are wayyy tooo costly. Are the achromats any good or equally good or atleast tolerable?
