In astronomy, the Pleiades, or Seven Sisters (Messier object 45), is an open star cluster containing middle-aged hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The Milky Way is setting earlier and earlier by the days. When I reached East Coast at around 10:30pm, it was already on its way setting into the mega ball of sky glow emitted from the Marina Bay area in the east. Somemore, there were quite a fair bit of clouds cover and high haze. Totally not ideal to do any widefield subs for stacking. And Singapore unpredictable sky wasn't helping as well. After a few shots, clouds started to fill up the southwestern sky. Only managed to only 10 shots and this is the best single exposure shot I have.

Kodak E100G is Kodak's last professional transparency film available. Having used the best transparency film for astrophotography, E200 for years now, I decided it was time to try Kodak's last remaining Ektachrome.
Here is a two frame mosaic, each a 20 minute exposure at f/3.4 using my Pentax Spotmatic II and 50mm f/1.4 SMC Takumar.
E100G lacks the red and blue response E200 holds in spades, but is more sensitive to greens. That is typically a bad formula for an astro film, as skyglow and manmade light pollution would record predominantly.
Reciprocity looks good and with a one stop push this film would be a great alternative to E200 if shooting the brightest regions of our Milky Way, such as those in Sagittarius and Ophiuchus. Star colors are well rendered.
As seen here, the film did record the California nebula and a very pale blue Pleiades. More interesting however is that it handily shows the Taurus Dark Cloud and what appears to be the Zodiacal Band running through Taurus.

A tumbling satellite can be observed just left of NU Ori in the image, a few satellites passed my fov when imaging this object.
I took these photos on January 4th after attempting to capture comet 45P/Honda–Mrkos–Pajdušáková, sadly it was too low on the horizon for me to discern from the skyglow. These were the first images I took with my new optical system by which I am very happy with it's efficiency and field of view.

I moved the Sharpstar coma corrector to this scope and am very pleased with the results. It actually reduces the FL by 5% to F 4.8 and gives good results to the edges of the 4/3rds sensor. Downside is it need quite a bit of back focus...which isn't a problem since the Apertura comes as more an imaging than visual newtonian.

My first attempt at the Leo Triplet with my Canon 60D and iOptron Skytracker. 300mm lens at ISO5000, 90 sec exposure, f/5.6. Tracking wasn't as good as usual tonight and there was a lot of dust in the air (more skyglow than usual). For the record, these are 35 million light years away.

Austin skyglow to the SE limited exposure time. The nova was still visible with averted eyesight in the skyglow. It shows up nicely in binoculars or camera.

M27 - single image 120s @ 1600iso, EOS1100D, 8" richey-cretien astrograph w/ focal reducer. Postprocessed to enhance contrast and remove skyglow.
I didn't notice this one until after I'd downloaded the photo. I was trying to get photos of the Milky Way. There were lots of shooting stars and satellites that night. (Hue adjusted to remove orange street light skyglow)
Two places around central Catalonia in northeastern Spain, using identical camera and RawTherapee settings (except black point to obtain similar brightness).
My first imaging attempt using the Celestron Neximage 5 camera. Didn't play around too much with stacking program, pretty much used the default values. Some nasty skyglow from light pollution. I tried to eliminate it using Photoshop to make the background darker black, which accounts for the unnaturally sharp edges around the ring system.
I'm a fan of perspective shots. Its easy to forget that about the only thing visible to the naked eye in this frame is the bright star Phecda (which sits at the bottom of the Big Dipper's bowl). In perspective this image taken with a 4 1/2 inch telescope renders the galaxy M109 rather humbled, certainly not from its perspective, but from ours. Other more distant galaxies are little more than tiny smudges here.
Sometimes its good to remember the frame filling images are often of things that are quite small.

The Flaming Star Nebula (IC 405) as seen in the back yard. This is a sum of 72 lights over 3 nights in November, 2012. Each light is 10 minutes at 400 ISO.
Used the Stellarvue SV4 refractor with the SV F6 flattener.
Taken with the full spectrum modified Pentax K10D camera. Used a Peltier cooler on the camera with temperatures between 5-10C. Most subs were at 8C. Baader Moon and Skyglow filter used with UV/IR filter stacked on two nights. On the final night, I used an IDAS LPR filter.
The frames were calibrated using Maxim with 256 bias frames, 95 darks, and 2, 21, or 53 flats depending on the day.
Stacked using DSS to make the mosaic. PP with PixInsight for crop, DBE, MT, ADCNR, and histogram stretch. Exported to LR3 for final touch and upload.
I'm happy with this shot. I would have liked to have better framing, but as it stands this is not bad for being captured in a suburban location. There was flexure in the RA direction. I'm working to solve this problem.
Here is the plate solve results:

Lyra in June 2014 from the backyard as seen with an unmodified DSLR with a portrait lens.
Taken over several nights as a part of testing to prepare for GSSP 2014, I put the Pentax K10D camera on a non-goto Losmandy GM8 mount and let it track guided for 5 minute exposures at 100 ISO and in-camera noise reduction enabled.
Used two lenses:
smc PENTAX-A* 1:1.4 85mm
S-M-C Takumar 6X7 LS 90mm f/2.8
Both were at F4.
The 67 lens was coupled with an adapter and an IDAS HEUIB-II filter was attached. This seemed to help control out of focus NIR.
Blue halos abound, even with the ED elements in the 85mm lens. I tried using a B+W 486 filter on the lenses but this caused additional flare with Vega. Might be a worthwhile addition if imaging in areas with fewer bright stars.
Made some efforts to capture flats but the stacking in DSS over compensates and I opted to just drizzle stack and crop afterwards.
The total data set is 36 subexposures at 5 minutes each for 180 minutes of integration over June 3, 5, 7, and 9. Additional exposures were made on other nights and were removed from the final stack due to issues with tracking or focus.
Stacked with DSS with a custom rectangle and 2x drizzle. Processed in PI with DBE, slight saturation curve boost, Masked Stretch Script, Histogram Stretch, and final masked curves to drive the background skyglow down.

A cold, blowy day in San Francisco. Beautiful too. Hard blue sky, crystal bright sunset and a nice wind from offshore that lets you know you are NOT in Kansas. Sheesh. We walked around both arms of the breakwater, and when it was dark, went back to Ghirardelli Square, where there were not seats immediately available for dinner, and I didn't really have tourist prices in mind for the evening anyway... So Reason prevailed, and we blew our big bucks on ice cream sundaes, talking about what we'd seen, and how much we liked ice cream sundaes, in the suddenly VERY warm ice cream parlor... YUM! Dinner would just get in the way. Funny how that works. Then we drove home for dinner, maybe picked something up, but not the $$$.
As you can see, the deck of the breakwater and the wall at its edge have rotted and are closed for repair/replacement. Half the width of the roadway is open, half is coned-off and marked as dangerous. Maybe 'abandoned' puts it too hard- consigned to its fate might be more apt.
DSC_0415
Finally, a use for ISO 102400! (Also known as H2 on the 5D3). I shot this engaging target at the three highest ISO speeds my camera can do: 25600, 51200, and 102400. By the middle setting, I could tell the reflection nebula was showing through, even though the skyglow was intense. To set the scene, this was shot on my front doorstep, in the middle of a town, with a streetlamp almost directly opposite. Yet at this sensitivity, the faint blue glow was visible straight out of the camera - so I worked hard in Lightroom to remove the orange and bring out the detail. I decided, after processing, that the highest ISO worked best - even with the extra noise, it was worth it, because while the stars weren't much brighter, the nebula was.
This went through several passes of rebalancing, noise reduction, altering levels and so on. But this is still what the camera recorded - selectively filtered, you might say. If I can do this at home, imagine the possibilities in a dark sky location! I've added some extra star designations with apparent magnitude, to show how sensitive the setup is - better than +13.
I don't know what causes the vertical banding - possibly the structure of the sensor. Note, some of the fainter blueness, in the middle, is camera noise - it was brighter in the centre. In the three shots, as the sky had moved, I can tell which brightness is real, and which is illusory.

There has been chatter around astrophotography message boards for some time now that a photographer can partially eliminate "sky glow" from the night images with a relatively cheap Hoya filter called a red intensifier. It is touted as the "poor man's astrophotography filter" because it is a good deal cheaper than most purpose made astrophotography filters and it comes in the standard sizes to fit most camera lenses.
Briefly, sky glow is the ambient light given off by street lights, safety lights and other forms of illumination that obscure our view of the stars. The less sky glow, the easier it is to see star. This is why the view of the Milky Way is always better in the country, for example.
Without getting to pedantic, I'll just say that the majority of sky glow falls into to distinct wave lengths of light that are both roughly in the red area of the visible spectrum. This is why many night shots have a rusty, muddy look. The color is due to the elements used to generate the light (mercury and sodium, I think... I'm no scientist) which each fluoresce at a different wavelength or color. The Hoya Intensifier (also called a didymium filter) is a filter that is designed to photograph autumn foliage and what it does is cut out the rusty orange found in some turning leaves and just let the red come through. This is great for astrophotography because that same wavelength of light also happens to be the one emitted by mercury lights (which make up many street lights). However, it doesn't cut out the sodium lights so you still have some sky glow to contend with, just less of it. By playing with your image in your favorite post-processing software you can somewhat notch this now dominant red light out as well. It is an imperfect solution but it gets you a little better than half way there.
Last week I went up to my favorite spot for photographing lightning while a storm was rolling in around 2 AM to try to get some lighting shots. There was too much fog to get good photos of the lightning but I had brought along my Intensifier filters so I decided to give them a whirl and see how much sky glow they eliminated in what amounts to a tricky lighting situation. See, the thing about fog is that it refracts light around all over the place, which is why its hard to see when you are driving at night in the fog. The light from your headlights ends up creating a big bright cloud in front of you. Much the same thing happens with city lights on a foggy night.
Below are two exposures taken back to back (each at f/10 ISO 100 for 30 seconds). The first is without the filter the second is with it. You can see that the filter cleans up a lot of the haze in the image but it does make everything look pretty red. The top image in this post was further toyed with in Nik Color Efex Pro 4 and Nik Dfine 2 to try to bring out some contrast and detail. The image was also processed with Aperture to tone down the saturation of the red tones that the Intensifier left behind. I also bushed out some of the more obvious blue shades that show up when you start taking the red spectrum out of the image.
Anyway, I didn't get any lightning photos but the clouds ended up looking pretty interested and foreboding and the whole scene was generally improved by the addition of the Hoya Intensifier (didymium) filter.
So, if any of you astrophotography folks out there were wondering what this filter did in pretty much the worst possible shooting conditions, you can now see for yourself.
And just for fun, here is a version I edited further in Nik's Snapseed on my iPad.

The Orion Molecular Cloud Complex (also often referred to as simply the Orion Complex) refers to a large group of bright nebula, dark clouds, and young stars located in the constellation of Orion. The cloud itself is between 1,500 and 1,600 light-years away and is hundreds of light-years across. Several parts of the nebula can be observed through binoculars and small telescopes, with some parts (such as the Orion Nebula) being visible to the naked eye.
The Horsehead Nebula (also known as Barnard 33 in emission nebula IC 434) is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is farthest east on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. The Horsehead Nebula is approximately 1500 light years from Earth. It is one of the most identifiable nebulae because of the shape of its swirling cloud of dark dust and gases, which is similar to that of a horse's head when viewed from Earth.

This is an image of Messier object 1, the Crab Nebula. Taken as a part of a test done in the back yard to check the way the PEC was working on the mount. I was also testing to see how well double stacking the Baader UV/IR filter with the Moon and Skyglow filter would work to give tighter stars.
I was pleased with the results of the double stack when using it on the SV4 refractor. On the Mak, it gave better results than expected. I was able to get better looking diffraction spikes for focus so it helped ensure good stars.
The stack is the result of 10 subs of 10 minutes each at 400 ISO using the full spectrum modified Pentax K10D camera on the 127mm Orion Maksutov Cassegrain operating at F13.1.
Only after taking these pictures and then looking at them a day or so later did I realize that there was something moving in the frames. It required a bit of work, but I believe that the object is identified in this list from the Minor Planet Checker:
Object (33078) 1997 WN35 RA 05 34 23.2 DEC +22 20 36 Magnitude 19.9 Motion in Arcsecs/Hr: RA 76+ DEC 0-
The finding of this object in the data meant that I had to get something out of the stack, which meant that I would work it over via trial and error.
Data was calibrated in Maxim using 77 darks, 15 flats, 256 bias. I had some flawed darks so I spent a long time chasing the errors. Stacking was done in DSS. Processing in PixInsight for DBE, background calibration, masked stretch, A Trous wavelets for de noise and sharpening, and a few more curve/histogram stretches before annotation. TIF files exported and then passed through LR3 for publish.
