30 Quick Tips for Improved Telescope Viewing

We chose the 5SE as the best telescope for most beginners because of its size, functionality, and cost. We were looking for portability in a telescope, so we set aside the larger models, the 6SE and above. Then we set aside the 4SE model due to its more-limited capacity to offer views of deep-sky objects. If size is not an issue for you, we’d recommend upgrading to the NexStar 6SE; an extra inch of aperture opens up more light-gathering potential and thus more viewing opportunities.
In order for optically thick clouds to form, our models suggest that the planetary metallicity must be higher than 400 times solar. In planets that are more metal poor, the temperature for the condensation point of silicate clouds is too low, and no silicate clouds can form. In order to model the atmosphere of LTT 9779 b, we used the radiative-convective equilibrium model ScCHIMERA (see Arcangeli et al. 2018; Piskorz et al. 2018; Mansfield et al. 2021, for details). The model assumes thermochemical equilibrium, where elemental abundances of metals are enriched by a given factor, called metallicity, compared to the solar composition values of Lodders et al. (2009). The model further assumes that part of the stellar irradiation is transferred to the planet nightside and that the dayside radiative-convective equilibrium is equivalent to the equilibrium where the total received flux is .
It is possible to forget to remove these caps since they are designed to allow light through. If a red flashlight is not available, you can still use a regular flashlight; just cover it with red cellophane or red paper to help. This does not help when it is a full moon, but that is the night of the conjunction.
There’s a balance, and sometimes a smaller, cooled refractor (or reflector) can outperform a larger, not-yet-cooled reflector. One of the best ways to help raise public awareness is to offer views through your telescope with friends and neighbors. Sharing the night sky with someone will often get them thinking about what steps can be taken to improve the view.
For exposures of longer than about 5 minutes, the stars start to make small circles in the image. A telescope case will protect your investment when you are transporting it to a dark sky site or storing it in your garage or closet. Some telescope models have hard cases available, but most will fit into a soft-sided case that is made for a range of telescope sizes.
The Newtonian telescope comprises a curved light-collecting mirror, which can be found at the tube’s base. The light that hits this mirror is reflected back to the front of the tube, where a smaller flat mirror — oriented at 45-degrees — brings light to the observer who can see their chosen object. The optical performance that the Celestron Advanced VX 8 EdgeHD delivers is impressive, with crisp and clear views with no optical distortion or false color.
Again, both of these are on alt-azimuth mounts (which in turn are set on tripods). Today, these types of lenses are typically used in small consumer optics, such as camera lenses and virtual reality headsets. Diffractive lenses are known for producing blurry images, which is why they haven’t traditionally been used for astronomical observations. They concluded that one of the major bottlenecks preventing the construction of more powerful telescopes is the difficulty in constructing the massive mirrors required for conventional observatories.
Tombaugh was searching for the mysterious Planet X, as astronomers had noticed changes in Uranus’ and Neptune’s orbit that indicated another mystery object was ‘tugging’ on the planets. Discover the best telescope for beginners right here! and turbulence in the atmosphere will keep you from seeing clearly an object that is near the horizon. But while it’s useful to know something about the sky before you start observing, your first scope can be a great way to get to know the night sky better.
Similarly, you do not need a telescope to see Mars, Jupiter or Saturn. You may need one to spot Uranus, and you certainly need one to appreciate any of its unusual features – a caveat that of course applies to everything in the night sky. And unless you are a character who appears in comic books, you absolutely need a telescope to see Pluto (no longer officially a planet but still a prominent member of the solar system) and Neptune. Below 100x – Both Uranus and Neptune appear star-like and can be indistinguishable from background stars. Use a good star chart to figure out which one is in fact the planet you’re looking for. You should notice that the planets’ lights are steadier than the surrounding twinkling stars.
You may sometimes see it claimed that big telescopes are useless — or even counterproductive — in the presence of light pollution. There is essentially no truth to this claim, as explained in my page about Aperture Versus Light Pollution. 100x – The rings are now easily visible, though to some they still make Saturn look like an eye. A sharp eyed viewer can see the yellow color of the planet and the white color of the icy rings. Titan, being the biggest and brightest Cronian (Saturnian) moon will be the easiest to spot, while Rhea and Iapetus will be the next two brightest. Rhea is usually closer to Saturn while Iapetus is further out, and they are about 2.5x and 16x dimmer than Titan respectively.
