  1. I did not mean CA is appealing. I was saying 120mm with more CA, i.e. more light out of focus vs 76mm that has less CA but also less resolution is not an easy comparison and some people will prefer the first others the latter. Some people will prefer the 120mm with a violet blocking filter, which gives you a reduced CA view that is also a matter of subjective opinion. Otherwise, the 80mm vs 4" was because of price and portability. I find the 80mm the max for what I'd call "grab n go" portable, and also a good enough size for most uses. Lots of info to digest in this thread, I see they sta
  2. Oh my! I just checked online prices and the Evostar 80ED is £480 new now! I am sure it was just under £350 when I got it... Well, of course back then I could also buy almost $2 with a pound sterling...
  3. I will agree with some users above, that given your requirements the solution is definitely a little ED doublet. I would say not even a 4", I'd go with an 80mm (e.g. Evostar 80ED), which is very portable and surprisingly capable. For example, I had 2 of my scopes set up side by side one night, the Evostar 80ED and the Celestron 127 Mak, aimed at Jupiter and not a single one of the dozen or so people there thought the Mak was better. A trained observer would be able to get some extra faint details, but the much more colour and contrast of the ED make the visual experience easily superior - the
  4. Day time align is a feature of the Pro version. The free version has all functions related to "classic" alignment with the polar scope, including all the reticles (over 20 of them covering pretty much everything ever produced that I have been made aware of). But it's a hobby app, if someone would like the pro version and they do not like to pay for apps, I don't mind being asked for a free promo code.
  5. Sorry, no Android for the foreseeable future. My main phone is an Android, but I've never developed for the platform... No, you definitely don't need to polar align your mounts
  6. Don't worry, PS Align Pro is the version for Amateurs. I added the Daytime align tool Jiggy mentioned when I was going to the 2017 eclipse, but it seems that many of my users use it for night-time alignment when they lack a view of Polaris. So, the version currently under development has a new "Hop Align" tool, that allows you to center any star you can actually see (preferably not too far from the north), before the app "hops" you to the Celestial Pole, having used the reference star as a calibration point. Anyone interested in trying it out early, just pm me with an email to add you to
  7. Huh, this is a really late reply, but in case someone is looking for something like that, the polar alignment app called Polar Scope Align, (disclaimer: I am the developer) has several tools, one of which is a Deep Space Object database, that allows you to find an object using a "Push To" function (with the option to use an intermediate calibration star to hop from). More details about using it from the point of view of a user here. I am suggesting it as the SkyEye mentioned does a similar thing, using the phone gyro/compass, it does not actually connect to the mount to control it.
  8. I assume all manufacturers make them separately, I can't imagine an assembly line for all the mount parts and polar scopes together. They just make the polar scopes so they can just slide in and lock at a fixed position and during polar scope assembly they have a similar procedure to get the reticle both upright and centered. I would not be wondering if only expensive mount manufacturers bothered to center their polar scopes, but iOptron for example has been doing it since their first mounts over 10 years ago and they are price-competitive with SkyWatcher. Then again it could be wors
  9. For SkyWatcher current polar scope owners that use Polar Scope Align Pro (PS Align Pro), since version 5.5 there is another option of using the polar scope reticle in the random angle it was installed in. Taken from the app, the idea is that you first figure out at what angle it is installed in - the app will want to know what hour/minute mark points up at "home" position. There are a few ways to do this (on a level mount), borrowed from the app: So in the above example we know our reticle is installed so that 1h 30m is at top. We open the Rotated Reticle View in the app and enter it

  11. Interestingly, because I track manufacturer specs for updating my mount comparison charts here, I know that Skywatcher used to specify 25kg visual for the mount (18kg imaging though), and users generally felt it could handle even more, but when they introduced the much more expensive AZ-EQ6 they removed any mention of the 25kg left the 18.2kg as "generic" capacity and specified just a bit more (20kg) for AZ-EQ6 to make it sound better. Not sure if the AZ-EQ6 can lift as much, I've seen the NEQ6 Pro with some impressive loads. They did the same with the HEQ5 downgrading to 13.7kg from 15kg
  12. I suspect some of you with iPhones/iPads & equatorial mounts will be aware of the app Polar Scope Align. It has supported the Skywatcher 2012-2032 polar scope since it came out a few years ago and as it was quickly made clear it was never installed "upright" (unlike the iOptron, Tak, AstroPhysics etc polar scopes), users had to rotate the RA to make it upright (or at least have one of the 4 cardinal points pointing the top). So I had added a function (called "set zero position") where you give the app the RA on your hand controller the moment you had the reticle upright, and the next time
  13. I wrote a complaint to my local council and explained what I do and that the street light at the corner of the backyard is such a problem and they replaced it with one that limits the light angle to not disturb me as much. It depends on the council, so YMMV.
  14. And 3.2 is out. You now get a light pollution button that gives you a Bortle estimate and a proper World Atlas 2015 artificial brightness based color coding. Pressing the button opens up the details: Access to some new forecast sources under "Other" sources is added as well. Both the free and the plus versions got the updates, so no reason to not try it out And PM me with your email if you want to try new features before they are released!
  15. That's interesting, shameless plug, but when I was designing Xasteria as an iOS client for 7Timer, apart from the default icon view I offered a "text" view, for which I considered whether showing an arc seconds figure would be better than a percentage. In the end, I made it a percentage, to match transparency, but I made them both have 100% = best. I mean, in my mind, "maximum" seeing/transparency at 100% should be the best conditions, no? E.g.: I am still considering whether arcsecs might be better for users that know what it is, but overall I suggest amateur astronomers try out the
