Anyway, this scope should be able to give you a nice 2 degree True Field of View (with a very good low power eyepiece)

if it comes with 2" focuser u got a couple of options here:
uo 32mm 2" konig = 2.5 degree (around $250)
pan 27mm = 2.5 degree with higher mag (around $500)
pentax 28mm = 2 degree (1.25" focuser, around $300)
pan 24mm = 2 degree (1.25" focuser, around $500)

u can actually go to more than 3 degree with Pan 35mm or uo 40mm mk70 but will usable only when you go to mersing (singapore sky is too bright).

if you don't mind seeing coma on your fast scope, a cheaper option is to go with 30mm 1rpd that will give you 3 degree.

just my 0.02

Hi,

if it comes with 2" focuser u got a couple of options here:

Yes.... That's a Big If

Anyway, I think the practical good very low power 1.25" eyepiece usable for this scope in Singapore is the Pentax XL/XW 28mm which I'm currently using... anything lower(power) will either cause the background sky to be too bright or you'll see the central obstruction.

if you don't mind seeing coma on your fast scope, a cheaper option is to go with 30mm 1rpd that will give you 3 degree.

By the way, I think all the above expensive eyepieces you mention will show you coma... only less or more. You'll need a coma corrector to reduce or eliminate the coma. Also, you won't notice the coma if you look at dim object at low power, but you'll see it if you look at Pleiades.

Anyway, I still can't forget the wonderful view of M24 star cloud through this scope using Pentax XL 28mm in Mersing... [glow=red]WOW[/glow] 8)

Have a nice day.

PS: May be we should discuss this under equipment discussion section.

actually at first i tot the firstscope 76 is a some cheapo short tube refractor, turns out to be a cheapo toy newt. tasco seem to have lots of time to make such toys.

actually the optics is...reasonable BUT not for the price of S$414!! but you can use it as a super finder

I think it is not make by Tasco... it should be make by Sytna... Sky-Watcher also have a similar model. Anyway, I think it should be better than any Tasco scope... at least it doesn't put down "600x" outside the box. I think it is design to put on your coffee or study table pointing outside the window, so that you can take a peek at the sky when you are bore studying or working.

Have a nice day.

for that price, i can get a meade etx90ra with a very nice optics (i still missed mine

), a real planet killer.
you don't use a newt for finder

well some people use newts for finders but its not that easy to find those people
