Astrophotography – Can photographing the moon and / or stars at night damage the camera sensor?

The light from such objects is far from bright enough to damage the sensor. However, if you use very long exposure times to capture faint distant stars, the sensor can be damaged by overheating.

Most modern DSLRs have thermal sensors and shutdowns to prevent this. However, if you use an older camera and keep the shutter open with an external power source for hours, you may cause damage!

I'm not trying to be alarming, but I would recommend a series of short exposures (less than a minute) with intervening cool-down times for best results. Multiple exposures can then be stacked in software to reduce noise. If you don't have a tracking mount, you'll get star trails with longer exposures. This is another bonus for short exposures.

Thailand – Night buses from Bangkok to Hua Hin

I just want to take the bus from Bangkok to Hua Hin and reduce the likelihood of traffic jams as much as possible, so I want a night bus.

From a search query Night bus to Hua Hin I found data that I thought might be out of date or unclear when night buses came from Bangkok Eastern Bus Terminal (Ekkamai) to Hua Hin are available and how much time the arrival should take (3 hours, 4 hours, 5 hours).

By "night bus" I mean a direct bus (no stops) that is extremely unlikely to be stuck in a traffic jam because it is leaving at:

24:00 or 24:30
01:00 or 01:30
02:00 or 02:30
03:00 or 03:30

Are there such daily buses from Bangkok?

Features – WordPress night mode does not work for videos

I use this js for night mode. Everything works fine, but uploaded videos are also inverted. How do I fix the problem and uploaded videos are not converted to night mode or to certain divs?

var sheet = window.document.styleSheets(0);

var begin_enabled = false;

if(night_mode.auto_set == true) {
    var start_hour = parseInt(night_mode.start_time.substring(0,2));
    var start_minute = parseInt(night_mode.start_time.substring(3,5));
    var end_hour = parseInt(night_mode.end_time.substring(0,2));
    var end_minute = parseInt(night_mode.end_time.substring(3,5));
    var d = new Date();
    var current_hour = parseInt(d.getHours());
    var current_minute = parseInt(d.getMinutes());
    if( start_hour == end_hour ) {
        begin_enabled = (current_hour == start_hour && start_minute < current_minute && end_minute > current_minute);
    } else if (start_hour < end_hour) {
        begin_enabled = ((start_hour == current_hour && start_minute <= current_minute) || (end_hour == current_hour && end_minute >= current_minute) || (start_hour < current_hour && end_hour > current_hour));
    } else {
        begin_enabled = ((start_hour == current_hour && start_minute <= current_minute) || (end_hour == current_hour && end_minute >= current_minute) || (start_hour < current_hour || end_hour > current_hour));

var cookie_val = wpCookies.get('night-mode-enabled', '/');
if( null != cookie_val && 'enabled' == cookie_val ) {
    begin_enabled = true;
} else if( null != cookie_val && 'disabled' == cookie_val ) {
    begin_enabled = false;

if(begin_enabled == true) {
        sheet.insertRule("html, video, img {-webkit-filter: invert(1) hue-rotate(180deg);filter: invert(1) hue-rotate(180deg);}", sheet.cssRules.length);
        $('#night_mode_checkbox').prop('checked', true);
        wpCookies.set('night-mode-enabled', 'enabled', 60, '/' );
} else {
    wpCookies.set('night-mode-enabled', 'disabled', 60, '/' );

$( '#night_mode_checkbox' ).change(function(){
        sheet.insertRule('html, video, img {-webkit-filter: invert(1) hue-rotate(180deg);filter: invert(1) hue-rotate(180deg);}', sheet.cssRules.length);
        wpCookies.set('night-mode-enabled', 'enabled', 60, '/' );
        sheet.insertRule('html, video, img{-webkit-filter: invert(0) hue-rotate(0deg);filter: invert(0) hue-rotate(0deg);}', sheet.cssRules.length);
        wpCookies.set('night-mode-enabled', 'disabled', 60, '/' );


public transport – tourist – from Tokyo to Hakuba at night (10 p.m. to 11 p.m.)

There are buses between Nagano and Hakuba; They are operated by Alpico and you can check the schedule in the link. Unfortunately the last bus leaves Nagano at 8.10 p.m. Another bus is scheduled to leave Nagano at 9:10 p.m. However, it only runs until March 15th, so you can't use it. The first bus on the morning of the 24th leaves at 7.55 a.m. and takes you to Hakuba at 9.05 a.m. (train station) or 9.10 a.m. (Happo bus station). As far as I can tell, the JR pass is not valid.

The problem with the direct journey from Nagano to Hakuba is that they are located in two different parallel valleys and are required to cross a mountain pass. Therefore, this is not a common direction of travel, only buses serve the route and they do not do this very often. You can take the train; To do this, you'll need to take a limited express from Nagano south to Matsumoto and then local trains back north

There are two general routes from Tokyo to get to Hakuba by train:

  • Take a Hokuriku Shinkansen from Tokyo or Ueno station, past Nagano to Itoigawa on the north coast and from there by local train

  • Take the Limited Express Azusa from Shinjuku to Matsumoto and from there a local train to the valley.

However, your late arrival in Narita means that you won't be able to get from Tokyo to Hakuba on the same day, as the line between Matsumoto and Itoigawa is a very small local line with rare (Japanese-style) service. The last trains arrive in Hakuba around 10:40 p.m. You must leave Tokyo before your flight lands. So you have to break off your trip somewhere and stay overnight unless you want to spend money on a late night taxi Nagano – Hakuba (Nagano is probably the closest one that you can catch on regular trains to Hakuba before the night closes ).

I would like to suggest stopping off in Matsumoto, where Matsumoto Castle is located, one of the few remaining original Japanese castles, and definitely a sight to see if you can take your time. To do this, you must take the train from Narita Airport at 7.15 p.m. This may or may not work if your plane lands at 6 p.m.

That being said, the other most logical option is to interrupt your trip in Tokyo, i.e. H. Find a hotel there for the night. The next morning you can either hop on an early Azusa for Matsumoto or a Shinkansen to Itoigawa. In fact, there is a departure from Shinjuku at 7:30 a.m. that will take you directly to Hakuba in 4 hours.

Summarize something:

  • A taxi from Nagano will likely be required to get to Hakuba on the 23rd. I cannot find a planned transport.

  • There are three ways to interrupt your trip:

    • In Nagano; The first bus leaves Nagano at 7.55 a.m. and arrives in Hakuba shortly after 9 a.m. Not covered by the JR Pass.
    • When you're ready in Matsumoto to play reaching the train at 7.15pm. Bonus: visit to Matsumoto Castle. The first train to Hakuba leaves Matsumoto at 5.58 a.m., then at 9.20 a.m. and then at 10.27 a.m. Travel time: 1:40 a.m., except at 10:27 a.m.
    • In Tokyo; many options. The most attractive is probably the 7.30 a.m.Azusa from Shinjuku, which goes directly to Hakuba at 11.27 a.m. This is the same train that departs Matsumoto at 10:27 a.m.

The most recommended website for checking departure times is, where apps for iOS and Android are also available. I personally use the JapanTravel app, which is also available for iOS and Android. Google Maps and Apple Maps are also great for checking train schedules.

Note that depending on where you are in Tokyo, a different route may be faster. When looking from Tokyo station, the options for Hokuriku / Nagano Shinkansen seem to be faster, although they look less logical on a map. If you are in control of where your Tokyo hotel is located, this is worth considering.

public transport – tourists – at night from Nagano train station to Hakuba (10 p.m. to 11 p.m.)

I will arrive in Tokyo on March 23 at 6 p.m.
The problem is that I didn't plan the time it took to get from Tokyo to Hakuba, and after looking at our options, I found that the earliest I can get to Nagano (with the Shinkansen – is already a JR pass). is around 10 p.m.,

We are a group of 4 people and it has been quite a challenge to find transportation to Hakuba at night.

I wonder if there are local companies that specialize in private bookings or even night transportation to get to the Hakuba Valley.

Thank you very much.

Trains – Niagara Falls night ride to NYC

I want to take the bus (or train) from Niagara Falls in Canada to New York City overnight. It is planned to depart in the evening on April 29 and arrive on Thursday morning.

So far, I have only been able to find a Greyhound bus that left at 4:45 p.m. and arrived at 3:35 a.m., which is a bit early.

So the question is whether there is a bus or train that will leave Niagara Falls (Canada or USA) later than 5 p.m. and arrive in NYC the morning of the next day.
