Not entirely sure this was worth posting, but gives me something to do whilst I wait patiently for the sky to clear.
I took this on 2 September, having waited since 5 August for a clear sky. Transparency was opaque ( had to concentrate really hard to pick out Cygnus!), but I thought what the hell. So I suppose under those conditions, this could be considered a fair result :) (processing aside!)
I'll give this another go when the visibility is better, and the moon and cloud have gone away.

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.

Did another round of shoots after midnight. The earlier shoot ended prematurely by clouds. At the time I was shooting this series of shots, Sagittarius was about 60 plus degree in the sky and night sky is reasonably clear of clouds & haze. The camera was titled towards the zenith region.

This is a stack of 68 frames at 100mm f4.5 and 2s - using DeepSkyStacker.
You (well, I!) can just make out the ion tail going straight out, slightly to the left of the diffuse, curved dust tail. The sky doesn't get super dark around here, so it was hard to get enough signal - plus on reflection I should really have used my f2.8 100mm lens rather than the 100-400mm!

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!

A wide-field view showing the area between delta and epsilon Cassiopeiae that contains the open star clusters M103, NGC663, and NGC659 (see the image notes for locations). The bright star to the lower left is delta Cas, while epsilon Cas is out of the field of view to the upper right (celestial north is off toward the lower right). M103 is one of the smallest and most distant open star clusters in the Messier Catalog and was the last object that he added to the list.

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/

Pretty happy with this one from my light polluted backyard. I will definitely revisit this one over the next few months and get some more data.
This is M33 after a long time of processing. You can see more about this galaxy on Wikipedia.
The original lights came from the evenings of September 18 and the night of September 23-24, 2009
Taken with my Pentax K10D camera with the Stellarvue SV4 scope, operating at Prime Focus. A field flattenter was also used as well as a Baader Moon and Skyglow light pollution filter. Tracking was done with the Orion Starshoot Autoguider using a Stellarvue SV 70 ED. The DLSR in-camera noise reduction was turned off. Most shots were done with using the Pentax remote control software to do bulb interval shots. I allowed about 2 minutes of time between shots to give the camera a chance to cool off and for the batteries to recover.
Most of the darks were recorded well after the lights in an effort to help understand and control the noise that is generated by this camera. I learned that I had to be vigilant regarding IR light getting into the camera when making this library of darks. Also, it appears that the telescope body itself seems to act as a heatsink for this camera, making collecting darks requiring connecting the camera as if it was in the field.

Processing was with PixInsight LE 1.0 using the instructions provided by Rogelio Andreo regarding gradient subtraction:
blog.deepskycolors.com/archivo/2010/05/
Further processing was done via the tutorial at this page from David Nash's website:
www.davesastro.co.uk/techniques/pixinsight_tutorial/index...
I'm extremely happy with how this image turned out. I know that there are a few gradients still showing up. Still, this is much better than I've been able to get from what I've always known was good data. The missing bits were getting a library of decent darks and flats and bias frames to give DSS some meat to chew on.
Finally being able to follow what is happening in PixInsight really helps as well.
Now I'll try to fill in the holes in my other data from last year and I'll see what I can get!
Quelques tentatives réussies de capturer la comète C/2012 S1 ISON. Malheureusement, la queue ne se détache que très mal du fond du ciel. Les raisons peuvent être le début de l'aube et la présence de la Lune presque pleine, bien qu'à l'opposé. Je tenterai de combiner les 17 fichiers d'assez bonne qualité avec Deepskystacker ou IRIS.
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.
I knew I had to do this - the last one wasn't too good. And I've now replaced this photo three times!
Think I've got about as much as I'm going to get out of this one. I'm pleased with it now, and will leave it alone! :)

I know this is not good picture, but first ones are always like that. ;) I´m hoping to get back to this tonight.
Nights are getting darker and darker.

The center of the Milky Way. Includes the constellations Sagittarius and Scorpius. Numerous star clusters and nebula are shown in addition to the dark dust clouds between Earth and the galaxy core. 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.
