This evening Comet C/2018 Y1 (Iwamoto) passed in front of the spiral galaxy NGC 2903. Observing conditions were pretty poor for this initially, with a lot of high cloud and a bright half moon. However, the cloud gradually cleared and I watched the slow movement of the comet over a couple of hours.
This image is a stack of sixty five 10 second exposures for a total exposure on the galaxy of 11 minutes or so. Because the comet was moving relative to the background stars it's smeared out into the greenish line from centre bottom to top right. The line has gaps because some frames weren't good enough to stack.
Messier 106 galaxy, also called NGC4258, centered within the picture.
Also NGC4217 edge-on spiral galaxy is captured on top of the image, with the other NGC4346 and NGC 4220 with low visibility.

An untracked/unguided, short-exposure view of the western portion of the constellation Leo the Lion including a faint trace of the 9th-magnitude, barred-spiral galaxy NGC 2903. This galaxy appears just south of the star lambda Leonis (upper right edge of the full image and better seen in the enhanced image insert at the bottom right of the picture).
I suspect that the only thing that I've recorded is the brighter center core of the galaxy, although I can just make out a slight elliptical shape in the image (I think, it's quite small). In any case, stars down to the 12th magnitude were recorded in this image as verified with the Cartes du Ciel star charting software (highly recommended free download).
The sickle-shaped asterism that forms the head of Leo the Lion is also identified and is best viewed in the full-sized image ("View all sizes" under the Flickr light box -- press the "L" key to toggle the light box).
Captured on December 4, 2011 between the hours of 4:54AM and 5:04AM PST from a significantly light-polluted, near-center-city location using a Nikon D5100 DSLR (ISO 3200, 4 seconds x 90 or six minutes total exposure integration time) and a Nikkor 50mm AI-S 1:1.8 lens set to aperture f/4.

The same 12 exposures, but this time I got hold of Deep Sky Stacker and used that to register and stack all the images. It chucks out a 32-bit TIFF, which I tweaked a bit to produce this image. I'm impressed - pretty sure that's a dust lane just above and right of the nucleus.
First go at Astrophotography! Learned lots of things for next time! But happy with how it turned out! :)

M13 - The Great Hercules Cluster. This 11.65 billion year old formation of stars is one of the most impressive globular clusters in the northern hemisphere. Containing over 300,000 stars packed into a 145 light year sphere, the center of this object is 500 times more concentrated than its outer perimeters.

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.

On the nights of August 11th and 12th, I setup my Canon T1i on my LXD75 mount to track the sky with a laptop to continuously shoot 30 or 60 second exposures of a patch of sky including part of the constellation of Perseus.
I was hoping to catch several shooting stars to stack into one photo that would show how they radiate from Perseus.
On the first night I saw only 1 shooting star and caught none on camera. On the second night (peak night) In 3 hours I saw just 14 including one fireball that left a trail for 10 seconds or so. I caught 2 on camera. This photo shows the two shooting stars stacked into one photo.
I used a 2" Antares light pollution filter on my standard 18-55mm lens, using some tape to hold it in place. It definitely helped but there is a lot of purple noise or sky glow around the edge of each exposure.
In total i took over 500 exposures. About half were lost from dew collecting on the lens at times when it operated unattended (I left it running and went to bed). I may try stacking the better exposures as a wide shot of the sky.
Hopefully I'll have better luck next year or during the Leonids. I wish I had the camera back in 2001 when I counted over 1000 shooting stars in the Leonid Meteor Storm!

I wanted to see how much detail I could capture in Orion without a tracking mount. I was surprised to find 5 seperate nebulas in this image. This is a stack of about 105 pictures each shot at 4 seconds, f4, ISO 8000 with a Takumar 135mm f2.5 lens. It was then cropped about 50%. One of these days I'll get an astrophotography mount so I can capture even more. To give you an idea of what else is in that constellation, check out this picture with nearly the same field of view: www.flickr.com/photos/28192200@N02/5776855550/

Quelques tentatives réussies de capturer la comète C/2012 S1 ISON. Malheureusement, la queue ne se détache que très mal du fond du ciel.

Some attemps of capturing Comet C/2012 S1 ISON. Unfortunately, the comet's tail doesn't detach that clearly from the background sky. Reasons can be the approaching dawn and the almost full Moon, although it was far in the sky. I will try to stack the 17 good files I made in Deepskystacker or IRIS.

The beating heart of the scorpion, Antares, a red super giant, shines a bright reddish gold in this image. Also includes several Messier objects, including the larger Ptolemy Cluster (M7), the Lagoon Nebula (M8), and the Sagittarius Star Cloud (M24). Though faint, the red hue of the bright nebula IC 4628 is visible in the tail of Scorpius. Hover your mouse over the image to show identified objects.
