Thanks! I use Deep Sky Stacker for stacking, Fiji/ImageJ for most post processing, and if needed, Neat Image for noise reduction and Hugin for stitching.

hi,

Don't use Registax for deep space stuff ... only use it for solar, lunar and planetary stuff

For deep space image stacking, Deep Sky Stacker as Andy and I use is a great easy stacking program, then do editing of the stack in Photoshop etc

There are other programs that cost money, some lots of money and are much more complex to get to understand
eg, Nebulosity3

Hi thank you for advise- yes It its true- I would like to get deeper space but with my condition (I am from Prague) I have no much chance..(do you think that for example andromeda galaxy is relatively easy to take ?

I am located in an "suburban/urban" location, my night sky is horribly light-polluted (in addition to generally poor seeing conditions), so I would argue you have very good chances.

Hello,
I attach two images processed by Registax (two settings of filtering) and original image as well.
If you have somebody some experiences with Registax I appreciated some advice…o_Oo_O:wink:
Have nice days and lot of succes..

High resolution from the International Space Station:

Experience High-Res Science in First 8K Footage from Space
Article said:
Fans of science in space now can experience fast-moving footage in even higher definition as NASA and ESA (European Space Agency) deliver the first 8K ultra high definition (UHD) video of astronauts living, working and conducting research from the International Space Station. The same engineers who sent high-definition (HD) cameras, 3D cameras, and a camera capable of recording 4K footage to the space station now have delivered a new camera capable of recording images with four times the resolution than previously offered.

After somewhat reviewing this thread, I figured something is missing. The following non-media was not uploaded in the forum:It was intented to show complete vacuum, but, since there was nothing to see, I figured I might as well skip it ...

Went out last nite, 7th Dec, for the first serious observing/imaging session for a long time.

Was very disappointed, when I got to site after a long drive, that I discovered that I had grabbed the wrong scope mount drive controller.
The controllers are the same except one has a 8 pin RJ connector and the other has a 6 pin RJ connector
The scope mount I took has the 6 pin and the controller I took has the 8 pin :frown: :rolleyes:

As a result I had no tracking ability for my imaging
I had to keep exposures short but at the focal lengths being used, there is still some trailing.

Did some serious pushing of ISO settings to compensate a bit for the short exposures

Comet 46P/Wirtanen ... a comet with a large coma ( gas/dust halo) the size of a full moon, but the overall surface brightness is
reasonably low

Path of Comet 46P/Wirtanen for the first half of December 2018

I hope to get out again, weather permitting, on the weekend of the 14 to 16th Dec when the comet will be beside the Pleiades (M45) cluster. It will make a nice image

this image is flipped horizontal and vertical for us southern hemisphere observers
attached is a pdf file for the northern hemisphere observers

Comet 46P/Wirtanen

well, battling mosquitoes, a bright moon nearby, bright city lights making the sky glow. I managed to get the comet near the Pleiades.--
Ohhh and when I took the scope and gear out, the sky was cloudless. Within 10 mins of doing the alignment and ready to go, the clouds started rolling through ... shot through the gaps
30 sec exposure, 150mm, f5, 1000ISO, Canon 6D
Not exactly brilliant, but better than not at all

yup, that small fuzzy green blob approx. right of centre

I cannot find the blob Dave, looked hard on a calibrated screen and still can't find it. There are three stars in line in the centre a lone star left of that and then a blob left of that of that, is that it?

Last night was a Christmas Miracle: the night sky was clear for the first time in about 2 months, and the last night before the moon got too close to comet 46P/Wirtanen: here's a 1:1 crop of a single frame (8", 400/2.8, ISO 800). The bright star is (I believe) φ Tau.
DSC_5755.jpg


Unfortunately, doing 'comet stacking' with DSS is rather time-consuming, not sure when I'll finish the post processing (about 200 frames)... stay tuned.

Here's the best I could coax out of DSS- 200 frames covering about 2.5 hours of observing time, keeping the comet still and letting the stars drift. Also, either a plane or a satellite moved through the image field, so you can easily see the effect of non-zero wait times between frames.

762ac2c0-c2c1-44cb-91ae-9e72bf1379c9-original.jpg


The image has been downsized a bit, but if you think you can discern a short stubby tail on the comet, it's actually the result of non-perfect centering. This is also a tiny fragment of the entire image plane- suffice to say I'm still having problems with flat field correction.

Trying to 'double stack', so that both the stars and comet are 'frozen', resulted in a mess. Unclear what that problem is.

All in all, not bad for urban astronomy.

Following from the previous 3 image with experimenting with ISO and aperture settings.
This LMC ( Large Magellanic Cloud) image is a stacked version
Canon 6D, 70-200 f2.8 @200mm, 30 sec exp ...
3200 ISO, f2.8, a stack of 8 frames = 4 minutes total exposure time, no darks or bias frames.
For the non astronomy people ... stacking images helps to reduce the noise level
