Non-collimateable primary mirror?

I'm looking to buy a telescope and really like the idea of the Sky-Watcher Star Discovery 150i f/5
It has Wi-fi (which I wouldn't normally go for) but it also has the capability to be manually moved to look elsewhere and afterwards it will slew back to where you were originally looking.
Other Wi-fi enabled telescopes I've seen such as the Astro Fi series do not have this capability and can only be moved ...

Sun- Moon anomaly

I have been trying to get to the bottom of this anomaly and most of the solutions suggest its an illusion. This is based on the fact that I was using a photograph and that various factors need to be taken into account e.g. lens distortion, cylindrical projection etc. I ony used the photo to visually convey what I had observed.
I could easily have drawn on a blackboard what I observed and taken a ...

Deep Sky Tour

Possibly a little premature, I haven't got the new goto telescope yet! But I have downloaded the Sky Portal Mobile App onto my IPad and I have had a look at the Bonus Content from the July S@N Magazine. There's a pdf download for both the Binocular Tour and the Deep Sky Tour and there's an Argo Navis Deep-Sky Tour software download and there's a Sky Safari download. Will the Sky Portal app use the ...

New scope opinions..

I'm an "old" newbie looking to buy a low price starter. I fell in love with a newton but after all I read about the adjustments and the frailty of the design, I've turned to shopping refractors. I've never even looked through a scope before besides my riflescopes and I want to be able to use the thing, not work on it! Ok, to the scope..a Celestron Powerseeker 80EQ. At $100, that's not much....Question is, ...

Telescope viewing

So I've recently bought a telescope and I was viewing Jupiter last and I could see it with 4 of its moon. But Jupiter itself just looked like a ball of light (a bit like the photo attacked below). I use a Nova 114mm x 500mm reflector telescope and a 10mm lens with a 2X barlow. Was just wondering if there is any way I can better my view of Jupiter and maybe start seeing ...

ZWO ASI120MM not viewing planets

Hello. My first visit.
I thought that it was time to introduce the grandkids to astronomy, so I bought a really cheap 90mm GOTO Mak, not expecting very much.
I can’t use it outside yet as it is not dark enough while the kids are up, so I decided to practice from my living room and was very surprised when I got viewable images of the moon, Jupiter and its moons, Saturn and it’s rings ...

Dew shields fo Newtonian OTAs - do they work ??

I saw an ad on ebay the other day from someone advertising a Skywatcher 200mm Skyliner scope which also included a wrap round dew shield (non heated variety). I must admit that I've always assumed that a dew shield on an open tube Newtonian would be a complete waste of time since the mirrors would already be protected to maximum effectiveness inside the tube. Adding effectively an additional short length of tube in the form ...

Bino mirror mount

I have just purchased a pair of 25x70 binos. Am in the process of making a mirror mount. Can anyone recommend or advise on size/thickness of front surface mirror glass and where to purchase? I was thinking around 10" x 7". Are there any problems I should look out for before purchasing glass? Many thanks.

Go to without wifi?

Total beginner here so please excuse the totally silly question

Basically I'm looking to buy a go to telescope, to begin with to use in my garden but eventually to take further afield.

In my garden i have a strong WiFi signal, so the go to functionality will be great to get me started on what to look for in the night sky

However, because i have a lot of lights outside my house ...
