Hi Krishnam. What would you like to do with this setup? Imaging or visual/observing? If imaging, choice no.2 and no. 3 are eliminated. The tube of 8" f/6 is simply too long and heavy for CEM40.

I would be doing astrophotography

The Skywatcher has better mechanicals. It is likely your best option.

 The ioptron one has GPS and wifi option available . Will it make any difference ?

I’m afraid your currency is a mystery to us in the UK 😀 but I have the EQ-R Pro and it’s an excellent mount and will easily handle the payload 

It is in Indian system 😂. Wait I'll convert it into $ , 

1- 2,103$ (skywatcher)

2- 1,952$ (I-optron)

3- 2,311$ (I-optron with istarFi)

I want to put my gso 8" f/6(dob mount) (13kg) ota on a go-to mount . I have shortlisted these : 

1- skywatcher EQ 6R go-to ( cost : 1,58,400 INR )

2- I-optron CEM40 with polarscope go-to mount (cost : 1,47,000 INR )

3- I-optron CEM40 with I-polar and IstarFi go-to mount (cost : 1,74,000 ).

Which one should I buy ?

Baader recently introduced a new small format of solar film, if your scope is no larger than 130mm (plus 5mm of clearance on each side) this 140mmx155mm will do and cost very little.

But why a rectangular sheet, you ask, since a square would leave less leftover film? Because the leftover can be used to cover the finder and/or a very small scope.

I have an 8" dob. 

I was using a solar filter . And due to a mistake , a hole is created at the centre of the filter . Can i do something to rapair it or should a buy a new solar film ?

Not all UHC filters are equal.  If you can afford it, I have found the Astronomik UHC filter to be very good with a nice tight band pass and good transmission. This means it is highly selective and for that part of the spectrum it does let through it lets through a high percentage of it.

But here in India , astronomik filters aren't available . Skywatcher ones are around 5000rs (71.58 dollars) and a cheap uhc filter around 1600rs (23 dollars) (SVOBONY)

If you know where to look, what you're looking for and have decent skies, some globs can be seen with just a pair of 10x binoculars. If your eyes are really good and you have really dark skies, you might even be able to see them naked eye. Won't be much detail at lower magnification though. At 40x, it should be more than enough to see something like M13.

I live in red zoned area of lp

What should be the min magnification to see star clusters , nebulas or galaxy . I have 200mm 1200mm dob and a 30mm 2" ep which gives me 40x magn . Should i keep searching with it or should try with 1.25" ep . I have 20mm , 12.5 mm , 9mm 6.5mm ep (1.25") . 

Will a cheap UHC filter work ?

So will i see (or make out )north america nebula fron UHC filter ? 

GSO IR filter or SVBONY UHC filter for visual astronomy . I have GSO 8" F/6 dob and i live in red zoned area of light pollution . 

Should i go for gosky lpr filters ? I live in red zoned light polluted area and eagerly want to see star clusters or nebula or galaxy which are not visible under lp skies . I have GSO 8" f/6 dob 

I have an 8" f/6 dobsonian by GSO . It has an altitude tension and balancing system . It comprises of a scale and the telescope can be moved up or down few centimeters to attain desired balance . Please help me and tell me that at what mark should i lock my scope if i use it with 1.25 or 2" ep to prevent it from sinking .
