I think the telescope and mount весьма are well designed for their stated purpose: an all-in-one, first powerful visual observation package. However, the quality assurance during actual assembly and shipping, I suspect are pretty lax compared to what they could be. When it first arrived, the telescope was quite badly out of коллимирование. Many screws were not tightened properly (e. g. secondary mirror holding кольцо). Most frustratingly, some gears were not propery fastened to their inside the shaft mount, causing me no end of problems with goto accuracy initially.
Since I was new to this Kind of telescope, it took me a few months to get all these problems fixed. So as I said, the design is intended great, but the actual workmapship in the factory very sloppy.
во всяком случае, after fixing those initial issues, I now have a great observation tool. For visual observing, there are a few extremely useful accessories I would highly recommend:
- the Power Tank portable battery. Using AA batteries is not sustainable with this scope: it'll eat through a fresh set of fully charged ones in less than 3 hours.
- shorter focal length eyepieces. This is a very capable scope, and to see detail on the moon, planets, or double stars & star clusters, you'll want more power than the supplied eyepiece 25mm. I am very pleased with the Celestron X-Cel LX 18, 12 и 7мм eyepieces.
- 6.7 the focal reducer, paired with a long focal-length eyepiece (I have the Omni 32мм). This is extended for viewing, faint targets, like nebulae and galaxies. Obviously you'll likely want to find a dark site to appreciate them properly.
- a dew shield, if, like me, you spend many hours outside during cold nights.
For astrophotography of bright, small targets (moon, sun, planets), this is an excellent scope, if paired with a suitable planetary webcam (I use a ZWO ASI 224MC, paired with a 2x Барлоу). Even from my light polluted balcony, i'M getting nice results.
Getting into astrophotography of fainter targets, there are some issues:
- The alt-azimuth mount causes field rotation, and pretty much rules out exposures of more than a minute.
- The Nexstar SE is mount весьма accurate for visual use, but not really good enough for longer-exposure astrophotography. At 1-2 seconds exposure time, I have to throw away on average 25% of frames due to tracking errors. At 10 seconds exposure, I throw away about 65%, and at 20seconds exposure, at least 90%, meaning only about 10% of frames are usable.
- Auto Guiding DOES NOT WORK AT ALL. Even though there is an Auto Guide port on the mount, it does nothing at all when connected. Simply dead weight.
Таким образом, if, like me, you want a good visual, portable and affordable scope, and you can live with the Photo графический limitations, I think this is a good all-round package. I'M deducting a star for initial the poor workmanship: it is simple matter to fix, and is due entirely to laziness and carelessness at the factory and during shipping.
