IC1848 continued, Hydrogen-alpha mosaic

Still a work in progress, will probably work on some other channels to add.

I’ve not uploaded the video of processing the mosaic as it was necessary to use a downgraded version of the software due to bug in the current version, I had that version on my laptop, so I used that to stack the mosaic, but don’t have Video recording software I know how to use on the laptop.

Will re-do when there are more sub-exposures available, and the bug in the software is fixed.

Faffing Around, trying to get automated Astrophotogrphy working

OK, so the worst conception you can have about someone into astronomy, is that they sit around, outside, with a thermos flask, looking at sky pictures.

The truth is we, astrophotographers, sit indoors, during this time of self-isolation and social-distancing, trying to work out how to get the telescope to work itself.

This is fraught with problems, and a lot of the time, means going outside to check that everything is actually doing what it is supposed to do.

Quick video, feel free to fast forward, on how that process works.

Final picture to follow…

Practice Processing with Example Data from the Internet (M31)

This is an example of processing data of the Andromeda Galaxy, with Astro Pixel Processor. The data was obtained from the Internet, rather than captured with my equipment (cloudy and windy the last few nights).

Here is the link to the raw data:

http://www.astropix.com/html/i_astrop/practice_files.html

There are some other targets available there, I’ve seen some other processed data and the nebulae are quite astonishing.

An issue I have with using practice data, is that often the data is just too perfect, otherwise it won’t have found its way on to the Internet. It sometimes is more instructive to try and process bad data and make something good of it rather than process just good data.

IC1848 (Soul Nebula) Astropixel Processor Mutlisession / Multichannel Integration

OK, I wouldn’t go as far as calling this an instructional video, but it is my experiemce with using APP for Multisession and Multichannel integration. Comments welcome on this one!

Soul Nebula (IC1848) Revisited

So, another cloudless night, how lucky we are. Disappointed with the results of two nights ago, I revisited the Soul Nebula, and this time get somewhat better quality in places that were disappointing. Here are the new results.

I may try and join the two sessions together and see whether I can pull any more detail from the two.

So. Now what we are able to do, if merge the results from Monday evening with the results from Wednesday and build a composite mosaic, I fiddled with the colour palette to bring out the detail. We can continue to add exposures and the mosaic would eventually lose the noticeable borders.

Soul Nebula (IC1848)

Decided to keep this as black and white, as had quite a few issues with the blues (achromatic issues) focus, so not possible to get a reasonable image in colour.

This is more of a test, looking at embedding more videos in the future.

Bode’s (M81) and Cigar (M82) Galaxy

Seems everyday is fraught with issues, which emphasises the real need to following a set workflow for set up of your rig if you are not lucky enough to have a permanent set up.

Mistakes this time round included, but probably not limited to:

  • Forgetting to attach counter weight to the counterweight bar
  • Mounting Filter-wheel in the camera train pointing downwards (M81 is pretty much at the zenith for my latitude, and hence the filter-wheel collided with the mount during exposures – which had to be discaraded).

It’s a case of constant learning. I did draft a workflow document, but the weather meant I did most of the set up in the dark. Time to update the document with the lessons learned and remember to actually follow it in the future.

5 120s L, R, G & B exposures, no darks, bias, or flats used (was annoyed and kicking myself for the problems, so didn’t bother.)
