Comet Iwamoto was at its closest to Earth this morning, so I headed out to dark skies southwest of Brisbane early this morning to photograph it. This is a FAST comet, so even though I only had 20 minutes worth of exposures I had to align them to the comet rather then the background stars,
20 x 60 second exposures at 200mm, f/4 and 3200 iso, stached in DeepSkyStacker and processed in Lightroom.
There is a faint tail visible extending towards 11 o'clock.
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!

First time trying stacking, I had very little idea what I was doing, but it came out ok. You can see some of the texture of the galaxy, and no star trails (I don't have a tracking mount). I learned a lot for next time I try it, mostly just MORE FRAMES.

The Orion Nebula (M42) is close to Earth in universe scale at only 1,344 light years away. The nebula is visible to the naked eye, even in light polluted areas as a "fuzzy" star in the middle of Orion's sword,, to the south of Orions belt. This nebula is busy forming new planets and stars.

Comet c/2012 S1 ISON imaged from my front yard this morning! Note the faint cyan coloring of the comet.
Two "bonus" satellites crossed the field, one smack-dab through ISON's tail and a dim one in the lower left. Just above the middle of the dim one's track is a faint galaxy, NGC 3433. The brightest star is 53 Leonis.
The sky was brightening quickly as I was getting these images, hence the bluish cast in the lower part of the frame.

This is the Whirlpool Galaxy one of two major galaxies visible in Ursa Major. It is about twice the size of our galaxy and 27 million light-years away. It is an archetypal spiral galaxy seen head-on. This is the first time I've managed to record this galaxy with any success. I'll post a wider-field view of this later.
Discovered by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission on March 27th 2020, this long period comet is now on its way out of the Solar System having passed just inside the orbit of Mercury at perihelion.

I've recalibrated and stacked and worked this image a few times since I first attempted it. Each time I come back with one more bit of knowledge.
This time, I'm still calibrating with Maxim. What's new is that I'm calibrating with 2C increments. Thus, for the 10 lights, there's two sections for calibration. This significantly reduces the over and undercorrection that I was seeing before. Also, it makes the post process a lot easier to manage.
Same details as before:
10 lights total, each at 600 seconds and 400 ISO.
Scope was the Orion 127mm Maksutov Cassegrain guided by a ST80 with SSAG.

Calibrated to make FITs in Maxim. Then debayered and stacked in DSS 3.3.3 beta 47 with kappa 2 5 iterations.
Processed in PI: dynamic crop, dbe, masked stretch, masks made from extrated lightness, these maskes used on atrous and deconvolution, multiscale media transform used on the remaining layers to boost the brightness of the nebulosity, unsharp mask, new mask from lightness, curves used on positive and inverse of this mask to bring up saturation and rgb as well as drive the background lower.

I took more pictures of this object and added them to my previous session.
I think this is a little green, but I got backround quite dark..
I am still working to get flats right, but after testing I noticed that 50 frames without any calibrate frames gives me less noise.. And noise is the hardest to edit. Vigneting is easier..
I am going to make lightbox and I´m hoping to get opportunity to test it in this season, while nights are still dark.

GIMP 2.10
This was my major target and effort for Calstar 2012. Taken over a series of 3 nights from September 13-16. My first evening under the stars had the camera rotated in the wrong position, so I couldn't use the subs very well. Because the camera position varied from evening to evening, this became an exercise in making a mosaic as well.
Because of the mosaic layout, amp glow from the camera was a big problem. My previous efforts to use DSS and PI to calibrate and stack were not able to sufficiently remove the glow. In the end, I loaded up Maxim, pointed it at darks that were in the temperature range of the lights and let it do a full calibration. The stacking of the resulting 59 fit files were done in DSS 3.3.3 beta 47 as a Sigma Clip. Processing was done in PI where I cropped, DBE, masked stretch, NR, and then a small MT to tighten up the stars. Brought the images into LR3 for touches to fix the blue halos in the bright stars (artifacts from calibration) and some final lines from the mosaic.
Final stack of 59 lights of 10 minutes at 400 ISO. Calibrated in Maxim with 63 darks, 27 flats, and 55 bias. Shot with the full-spectrum Pentax K10D camera with the cooler attached giving temps ranging from 19-21C. Telescope was a Stellarvue SV4 guided with Maxim using Orion SSAG on SV70ED. All used on a Losmandy G-11.

bottom-right ... RA: 04 08 52.468 Dec: +36 43 53.97
Lessons learned: Maxim does a good job with non-linear amp glow areas. I'll be going back to some of my problematic subs to recalibrate. I'll have to see what I can do to fix the blue rings in the bright stars as calibration doesn't seem to control these well.

This is difficult object.
It didnt help, that moon was shining brightly. I still had to shoot this, because it had been cloudy for so long.
I didnt use much time to edit this. I want to have more frames (in dark, without moon) and then do proper editing.
But I am happy I got this much. Last winter I had only 10, or so frames..
