- www.kevin-palmer.com - There are a lot of astronomical objects which have names that don't seem to fit. But this object strongly resembles its name: the California Nebula. It is located in the constellation Perseus and is very difficult to see even with a telescope because of its low surface brightness. The nebula is made up of hydrogen gas that glows because of the radiation from the nearby star Menkib. Also known as NGC 1499, this nebula covers roughly as much sky as 5 full moons. On the right side of the image dark nebula can be seen. It is made up of insterstellar clouds of dust so thick that it obscures the light of stars behind it.

This was shot with a Takumar 135mm f2.5 lens at f4, iso 1600. It is a stack of of 20 2.5 minute frames, plus 8 darks, and 8 bias frames. An iOptron Skytracker was used to track the stars.

A planetary nebula is formed when a star puffs off its outer layers and these expand into space. They are not related to planets, but rather looked like planets to early telescope users - hence the name.

This is an image from April this year, but as with so many of my deep sky work I've included frames taken in previous sessions to reduce noise and therefore to help show subtler details.

29 x 1-minute unguided frames at ISO 6400 (new data) and 15 x 5-minute manually-guided frames at ISO 1600 (older data from 2013 and 2014). Modified EOS 600D & Revelation 12" f/4 Newtonian reflector telescope.

Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise and light pollution colour gradients reduced in CyberLink PhotoDirector. I also used Noel Carboni's astronomy tools in Photoshop Elements to reduce the prominence of the stars (which otherwise dominate after stretching the contrast).

This is now 275 subs over 8 sessions totalling 17 hours, and is slowly getting there. Still needs more time, but I suspect it will have to wait until next year now. Used a different processing technique to my previous sad looking version, and it seems to have done the trick. Got Hubble's Variable thingy in there this time as well :)

I won't be sorry to see the back of this :)

This year, I've returned to M31, which is one of my favourite deep sky objects. Conveniently located in the northern sky, large and bright enough, beautifully fits the field of view of my TAIR-3S 300 mm telephoto lens... And in any case an interesting and beatiful object in my opinion! It might even look more spectacular in a few billion years, when it will probably crash head-on into our own Milky Way. Too bad I probably won't be around to watch that...

For this take, I've increased the original exposure time from my first try in 2021 by about 12 times, to 4.5 hours. In total, four nights of observation went into this image so far. I also acquired a better tracking mount, and learned a lot about image processing since then (among others, photometric colour calibration using plate solving in SiRiL). Let's see how much more exposure depth I can add next year!

This is my first time combining multiple nights of data and also the first time I've done longer then 300 second exposures. This image has been tricky to process and I'll likely go back and try again. Some of the stars in my stacked image show some noticeable trailing, but that isn't the case with most of my subs. The stars aren't quite pin point in the subs either though. I'm thinking its some refraction or other type of aberration from the extender. That thing is nice to have for the extra focal length, but it really isn't the best and kind of kills the great optics of the Canon 70-200 f/2.8L. I'm going to try stacking the image in PixInsight. Other's have suggested I use that instead of DeepSkyStacker as it's suppose to do a better job, but I haven't had success with it in the past. Worth another shot I suppose. Still, pretty pleased with this image. I know there is a lot of Ha in this region and that can be difficult to pickup with a stock DSLR so I think I did a pretty good job.

The Crab Nebula (M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus.

At an apparent magnitude of 8.4, comparable to that of Saturn's moon Titan, it is not visible to the naked eye but can be made out using binoculars under favourable conditions. The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 6,500 light years from Earth. It has a diameter of 11 light years.

Just for grins, I dug up all the 30-second M42 frames I've taken through my 80ED and fed all 120 light frames to DeepSkyStacker to see what I detail I could pull out. Looks like quite a bit. There are several seams visible on the right side of the photo where coverage was incomplete. I didn't entirely escape the red stripe problem either...

I was quite please with the level of detail present with only 2 Hours of integration.

The Elephant's Trunk nebula is a concentration of gas and dust located in the constellation Cepheus, ~2,400 light years away. The column of nebulous gas cloud is being ionized and lit up by a massive star inside (picture it inside the round section at the top of the trunk), and is thought to be a site of new star formation.

Personally, I like all the dusty, smoky regions surrounding it.

I have already attempted this one, but wasn't too happy with the noisiness and colour balance in my first try. So here we are again, this time with much more Hydrogen alpha data (collected 5+ hours, but only used about 3.5 hours worth thanks to clouds and haze).

Here, NGC 884 and 869 are shown. Commonly reffered to as "The Double Cluster", these two Open Star Clusters are reletively close to Earth within our Milky Way. The two lie in the constellation of Perseus. The Double Cluster is a naked eye object for some depending on age and location. Personally, NGC 884 and 869 are two of my favorite objects to look at. Because they are so large, most telescopes have to use low power magnification to veiw them, which makes the young hot stars really POP out from the background sky. Each star can be resolved, looking like a cloud of diamonds against the charcoal gray of the night sky.

I decided to take advantage of the new moon, drag my telescope, and do some astrophotography last night...even with the time change and losing an hour of sleep. I'd say the bit of sleepiness today was worth it to get back into Astro and get this shot of my first time imaging this nebula!

I polar aligned my mount using SharpCap Pro. My Sony a7SIII and adapted Nikkor 500mm f/4 P AI-S were mounted on an ADM vixen rail and secured to the SkyWatcher EQ6-R mount. The guide scope/camera was attached to the camera's hot shoe. I used PHD2 to autogude during the imaging session. DeepSkyStacker was used to combine all frames, and the outputted TIFF file was brought into PixInsight using: STF, Cropping, Dynamic Background Extraction, BlurXTerminator, plate solving, color correction, NoiseXTerminator and then the DSO was separated from the stars, and both files processed and stretched separately and then recombined using PixelMath. That file was brought into Lightroom for Metadata and EXIF tags, light post-processing, and cropping to the final image.

The Milky Way over Zion Lodge.

I wasn't thrilled about having the lodge in the photo. If I had planned ahead, I would have taken the shuttle bus up to the next stop to shoot the night sky, and walked back to the lodge (or taken the last shuttle).

I stacked six or so images in DeepSkyStacker, extracting two alignments (for foreground and sky). I also extracted and manually blended two exposures for the foreground.
