Here's a little experiment. The dotted line is the International Space Station (ISS) passing through the field of view of my small telescope, very near the interesting little object known as NGC 246, a planetary nebula sometimes called the Skull Nebula in the constellation Cetus.

This wasn't by chance. Watching for these sorts of coincidences, I consulted the trusty sky simulation software SkySafari and noticed that the path of the station would take it in front of a few interesting features in the sky, in addition to this one: M13, the Great Hercules Globular cluster in Hercules, Vega, the brightest star in Lyra, and The Veil Nebula in Cygnus.

Because of the tremendous difference in brightness, I captured the ISS and the nebula field separately. (The ISS is the third brightest object in the night sky, after the Moon and Venus). For the ISS pass, I made a short video with a Nikon Z 6 mirrorless camera and Explore Scientific 102mm f/7 refractor. The image of NGC 246 was made afterward with a ZWO ASI294MC camera and Nikon 80-200mm f/2.8 lens @200mm, 15 6-minute exposures processed in Astro Pixel Processor and Lightroom. The ISS track is in the correct position and scale, composited in Photoshop. In addition, the inset is an enlargement of a few video frames and shows some detail in the ISS.

ISS transiting the Sun captured with:

Focal length 2856mm, focal ratio f/28 and shutter speed 1/2000s @ ISO 320

Solar filter used (is a must to capture it): Lunt Herschel Wedge

Viewing conditions: Transparency above average, Seeing above average

This picture consists of 5 exposures stacked and is not cropped. It was shot with continuous shooting mode (6fps) in JPEG format.

The picture is normally white I added the orange color to see the details better and make it more pleasing to look at.

ISS transit details:

ISS distance (range) 541.8km, transit duration 0.71s, transit time around 10:08:08am, Sun altitude 47.0°

Finally after 3months I captured the ISS transiting the Sun. Mainly the bad weather in the past months delayed the capture and the fact it does not happen every week and also it need to be on a weekend (I had to work on weekdays during daylight).

Of course I’m not the first to capture it.

Thanks go to Phil McGrew for introducing to me and other photographer friends the idea of capturing the ISS transit and what tools are used for calculating such event. And Thanks to Ed Morana for writing the tool to calculate the transit.

AR means active region with sunspots and other activity.

I caught the ISS passing in front of the Sun again today, and didn't even have to leave my back yard! Thought I'd be clouded out but there was a partial hole just at the right time. A bonus was getting a sunspot (near the left edge of the Sun, AR2770), rather rare these days.

The geometry is such that the station is about as close as it gets, about 283 mi, so is relatively large, about 1/30 the angular size of the Sun's disk. The tradeoff is that it happens much faster than when it's farther away; the entire transit took less than a second. So I shot a movie to get as many frames as possible and combined individual frames for this composite.

star mask to protect the brightness/colour of the stars

- overall curve adjustment (s) to add contrast to the entire sky area

- local curve adjustment to the core to make it stand out more

- locally increased the saturation of yellows, reds and magentas

- SRBG conversion to match the capability of my monitor and the web to further insure an accurate print

- imported into photoshop and added the masked foreground for the final image

- Export as JPEG

This was my first shot at working with Pixinsight and i must say i am overwhelmed by the amount of options. Im looking forward to further honing my skills in post and also in the shooting itself.

Melotte 15 is an open cluster of bright stars located at the center of the Heart Nebula (IC 1805). Named for its discoverer, Philibert Jacques Melotte (1880-1961), the grouping of O-type supergiants is only about 1.5 million years old. "O" stars are the brightest and most massive known, about 20 to 100 times larger than the Sun! The lifespan of these hot, blue stars can be as short as 3-6 million years. Melotte 15 is about 7,500 light years away from Earth.

Despite mostly cloudy skies, I was able to catch a few glimpses of the Venus and Mars conjunction on October 5, 2017. This morning, the pair was an incredible 0.25 degrees apart. A small diffraction rainbow is seen as Venus enters the passing cloud cover. The photograph was taken with a Canon 70D and a Canon 200 mm f/2.8L II lens. (f/4.0, ISO 800, 5 sec)

I hadn't planned on making a time-lapse; however, after reviewing the images, I really liked this short sequence between the clouds.

Orion and the star Sirius, at left, setting in the dawn sky over the Chiricahuas on the morning of December 9, 2015. The orange star is Betelgeuse. Light from the eastern dawn illuminates the landscape. Haze added the natural star glows — no filter used here.

The sky is a stack of 5 x 90 second exposures at f/2.5 with the 35mm lens and Canon 5D MkII at ISO1600, with the camera on the iOptron Sky-Tracker to keep stars from trailing. The ground is from another set of 5 similar exposures with the tracker motor off, the eliminate blurring from the camera tracker motion.

南冕座分子雲 Corona Australis Molecular Cloud

多年前看到同好所拍的照片後已被這堆黑黑的東西吸引著。但是南冕座在香港的觀測仰角較低，加上香港的空氣污染，要拍這個天體實在苦惱。

去年到南半球外遊，看著它高掛半空當然不能放過這機會。

南冕座在天蝎座尾部的文東南邊。這片分子雲結構離我們約 500 光年，算是離我們比較近的造星區之一。黑厚的塵埃遮擋了背景的銀河繁星，也藏著年輕新形成的恆星。近中央藍色的是反射星雲 NGC6726, NGC6727, IC4812。旁邊的星團 NGC6723 其實在很遠的背景約三萬光年距離。
