I turned the 60 f/15on Mars and viewed at 100x with red #23 in. I was able to faintly see the general shape ofSyrtis Major and the associated Mare, along with the Sinus regions on the other side. Also felt I was seeing a small but brilliant polar cap along with general larger brightening that is a match for Hellas. I then rotated the two lenses 120 degrees togetherin their cell (while leaving the cell at same orientation as before.) The goal was to turn the"prism" to counter that of atmospheric dispersion in alt az orientation--rather than having it act partially additive as it had been doing. This indeed rotated the orientation, so the problem is inherent to the objective and specifically the rotation of the flint.

Of course you have DeLite and Nagler alternatives at 5mm & 7mm, and Delos at 8mm. But the Tak UWs are stellar! None of this is difficult to get a great result from. The PowerSeeker 60 is a refractor telescope perfect for terrestrial and celestial viewing on the go. The PowerSeeker can view the planets, moon, star clusters and brighter deep sky objects like the Orion Nebula and Andromeda Galaxy at night. The erect image star diagonal makes the optical tube ideal for using as a spotting scope during the day. The behavior of the pattern on either side of focusis not that of simple coma or astigmatism. If they are present, they are masked by the chromatism.Specification and optics are the same as the Startravel-80 (ST80) but supplied without equatorial mount/tripod and includes a 45º Erect Image Diagonal. The other bit of bad news looking at the kit is that the 20mm eyepiece is a cheaper design than that with the Celestron 70 Travel scope. This one has a much smaller eye lens and only about a 13.6mm field stop vs. about 19mm in the Travel scope's kit. I am pretty sure the problem is in the bottom element with the spacers attached. The color offset rotates with the bottom lens, independent of the top lens or the objective cell. If the cell was tilted then the orientation would not rotate when only the objective lenses were rotated. This is a relief since trying to correct focuser and objective cell orientations has proven difficult in the past. Something in the 20mm range for wider-field viewing - looks like the Televue Panoptic gets pretty good marks in this range, but very open to recommendations Setting up the telescope is a breeze, so you can enjoy the wonders of the universe in no time. Even on your first time out, you can assemble the telescope and its accessories in just a few minutes. The adjustable tripod legs allow you to customize the telescope’s height or place it on raised surfaces like a picnic table. The total telescope kit weighs in at just 3.8 pounds—perfect for impromptu observing sessions or transporting wherever life’s adventures take you.

Celestron PowerSeeker 60 60mm f/12 AZ Refractor Telescope

I have experimented with several similar entry level models. Almost without exception the objectives have been surprisingly good at any sensible high magnifications.Quite often the objectives are pinched due to the retaining ring being too tight. Forget the rest of the instrument though!. I have used them for solar observation and also built a binoscope with a pair incorporating a couple of monoculars for the eyepiece end.

At least future star testingwill be easier now that I have added rings to the OTA and don't have to rely on the unbalanced, shaky EQ1 mounting system. After the holidays I will see if I can get Celestron to send me a replacement objective. I did the same observation of Marswith the 80, using 100x (4mm setting on 3-6 Nagler) and red #23 to see a somewhat lower contrast outline of the dark regions as well as the brightening to the south, probably Hellas although I had some impression of what should have been the pole. This 80 seems to beconsiderably sharper than my original ST80. The 60 provided a little more detail overall. The 60mm f/12 objective was in mint condition (after a cleaning). Optically, the scope performs beautifully. It makes use of its full 60mm aperture. It's essentially free from chromatic aberrations. The star-test patterns (using a 1st magnitude star) were absolutely "beautiful". I've used Buttercup for solar, lunar, planetary and deep-sky visual astronomy -- and enjoyed every minute of my eyepiece time!

It is somewhat unfortunate that the tabsface the focuser. If they faced the other direction I would probably attempt pushing the baffle toward the focuser. It could actually be moved toa more useful position that way, and paired with a much wider opening baffle on the other end nearer the objective. I received the 60 f/15 scope today. Overcast and sometimes sprinkling, but I did get to point at some street lamps about 300 yards away, some other light poles, a cell tower and the mountains. Only tested up to 100x but I didn't notice anything amiss with the image. The mount actually seemed a little better than I expected. The scope might be useable on this mount with VSP's. The focuser seemed relatively smooth and tight for plastic. I have not tested to see how it handles an eyepiece and diagonal in the vertical though. Yes, I figure the 7T1 for 129x with the 60 f/15should be about the limit for my eye before diffraction begins to take over--assuming the optics are diffraction limited and the color is nearly negligible. I don't have an 8 withoutBarlowing a 16so the next step lowerfor me is a 9. I wouldn't be surprised if the difference between 100 and 129x with the scope was only image scale providing some confirmation rather than new detail. I see thatwith the 60ED going from 120x (3mm) to 144x (2.5mm). The TV60 is a little work of art. Compact, light, well built and the optics, oh the optics. Tiny 60mm perfection. First light for me was Jupiter. At 70x using a 5.2mm Pentax XL color correction and sharpness were breathtaking. I have not been so excited about a medium power view of Jupiter well, since I had my Sears scope. I also observed open clusters and Omega Centauri with it. Yes, binoculars will sometimes be part of my travel kit. But, the ability to change magnification allows more flexibility and the mandatory lunar/planetary fix.Something to give the best contrast lunar and planetary views at the high end of magnification my little scope can comfortably handle. My usual seeing conditions aren't great. Thinking 100x is maybe a good range to aim for, so maybe 6mm but maybe too small exit pupil?

Accessories include a 20mm and 4mm eyepiece, a finderscope, and a 3x Barlow lens. The two eyepieces offer different magnifications for low and high powered views. The 3x Barlow lens triples the magnifying power of each eyepiece. I have an FS60Q as a companion to the FOA60Q. I love them both at the same aperture, for different reasons, so I keep them both. I have some doubts about the coatings of the objectives. There seems to be a fairly strong set of reflections when shining a headlamp down the tube. I don't recall other scopes giving such an impression, but I will need to explore this some.The 18.2mm DeLite is a great place to start. So would the 24mm Panoptic or a used 22mm Panoptic (one of my favorites, which I still own 30 years later). But for a short focal length, consider (saving for) the not-inexpensive Takahashi UW 5.7mm. It's designed for flat field scopes, which the FS60Q is. It's right by the 6mm lazy-person's target. It has a roomy 90° AFOV and it's optically incisive for 105X. In the event you find a night of exceptional seeing where you can grind out more useful magnification, with the 5.7mm UW eyepiece you can get 210X with a 2X Barlow, or ~89X per inch, which is entirely within the competence of the FS60Q when seeing permits. The scope came with one 25mm MA 0.965" eyepiece. I modified a 1.25" 10mm eyepiece, and later a 1.25" 6mm Orthoscopic by adding home-made 0.965" barrels. Buttercup handles the increased magnifications beautifully. Setting up the telescope is a breeze, so you can begin observing in no time. Even on your first time out, you can assemble the telescope and its accessories in just a few minutes. The adjustable tripod legs allow you to customize the telescope’s height or place it on raised surfaces like a picnic table.
