Celestron Astro Fi 127mm WiFi SCT or Celestron Nexstar 4SE

Postby Sessy » Sat Dec 02, 2017 12:17 pm

Im wanting to purchase my first telescope and stuck on which route to take. Im looking to spend around $1000. The 2 im tossing up between are both Celestrons, either the Astro Fi 127 127mm wifi sct or the Nexstar 4SE.
Does anyone have any advice or another telescope that i should be looking at?

Why are you considering these, asking to find out your reason for wanting this type

As far as I can tell, the optical tube is identical for each of these. Its all down to the computerised mount. The classic SE uses a wired, dedicated hand controller. The 'Astro-Fi- appears to operate through a 'smart phone''. I guess by not providing a hand controller it cuts down the cost. To my eye the 'Astro-Fi' tripod doesn't look as sturdy as the SE. Possibly another way of cutting down the on the cost.
You can add a hand controller to the Astro-Fi, or a wifi adapter to the SE at extra cost.

Check which eyepieces and other accessories come with each of these. They can occasionally vary with local suppliers.

They are both nice telescopes. In the end you have to decide for yourself.
I use an 11" Celestron SCT (CPC 1100) on an equatorial wedge, housed in a 2.2m Pulsar observatory. I use a ZWO ASI1600MC and Canon 500D for imaging.

You have not replied to my question.

I have owned reflecting telescopes and refractors, and chose to come back into Astronomy with a SCT, perfect blend (for me) of ease and usefulness

Thanks for the advice.
To answer your question EIZO, i have been looking at these scopes as i have heard Celestron was a good reliable brand and these 2 have the most aperture within my budget. I have been stuck with the typical question "refractor or reflector". I was also looking at the Meade (ETX and Polaris). Im wanting to veiw the planets, moon and galaxies.

For the price and size of scope you will see very VERY little by way of planets in fact about as much in the attached image, remember as a rule of thumb in PERFECT seeing conditions for every 1" of scope you can have 50x magnification

So a 4" scope will give 200x mag, an 8" 400x approximately.

When I started out I went for a refractor, 5" acromat, then moved to the reflecting scope above, NEVER again will I get an EQ mount, as I have said many times if you are happy to kneel down for ages in wet grass and the cold trying to polar align it every time you go out fine, if like me you want to get it out of the car, and use it get a Mead/Celestron.

Preferably with star sense or sky portal, you can image with a NON eq mount, just not long exposures, say 30 seconds, for the Moon 1/500th is enough

I wouldn't want to underplay the restrictions of using a 4" reflector, but I don't think they are so bad. Planets would look small in the eyepiece, but the resolution and detail will be far higher than a photograph showing the apparent size. The phases of Mercury and Venus, and their changing apparent size would be seen well in a 4". The position and relative brightness of Jupiter's 4 brightest moons can be discerned, and at least some of the major belts on the planet will be seen. Regarding Saturn, the orientation of the rings, and in good conditions, the distinction between ring 'A' and 'B' will be seen. Several of Saturn's moon can be identified. 100s of lunar features can be identified. Many double stars can be logged. The brighter Messier objects will look good with its wide field. The brighter asteroids can be identified. A systematic observer could be kept occupied with a 4" for many, many years.

Equatorial and Alt-Az mounts both have their advantages and disadvantages. I have used both kinds and have been happy to maximise their strengths, and there are ways alleviating some of the weaknesses. The same goes for reflectors and refractors.

It is always tempting to justify our own choices, but I don't really think there are bad choices of telescope as long as the make is good, people learn how to use them properly, and make the most of their strengths.

If i were to go the Celestron Nexstar 4se would you recommend any eye pieces or barlows to help with magnification?
