What to do when the weather is bad? Use scientific data!

Recommended Posts

Astrofriend    82

Here is a project I have thought about over many years. What can I do with all scientific data that are out there?

I tested this already 15 years ago with the POSS-I data from Mount Palomar observatory with good results.

Now I'm just practising this how to handle the data and get something out of it. One easy task is just to make pictures from the data and compare it with my own photos. Just to get an idea how much worse my photos are compare to the telescopes at Mount Palomar.

Here you can see how I have processed the first two Messier objects, M1 and M13:

Even more exiting is if I'm in the future can do some science with it.

I have many cloudy nights so I'm desperate!

Hi,

Now I have finished the M1, M13, M31, M42 and M45. It's very interesting to study the details, remember these photos was taken when your grandfather was in action!

Clouds and clouds and even more clouds, what is happening with our weather?

Good then I have found a new part of the astronomy, scientific data. This is of course a bit outside amateur  astronomy, but what to do when we never nowadays have a clear sky?

This time I took a look at the Kepler spacecraft and it's data. Normally used to find exoplanets. But that data can also be used to examine variable stars. One big plus, the observatory is out in space, no clouds!

One of the more exiting thing I did was to set together 44 months of data as a GIF movie. And by luck there was one very clearly seen variable star:

It was a bit tricky to get this to be correct because the satellite rotate 90 degrees every three months.

To  read these files I need two new tools which found at NASA homepage. The DS9 Fits reader and Fv reader. The other tools was the ones I normally use, AstroImageJ, Fitswork and IrfanView. In the beginning I also used a hex binary editor, but didn't need it in the end.

      Hi all,
      Stacked image of 384 frames taken from a 720p mp4 with my Sony a6300 in prime focus on a SW Skymax 127.
      I started imaging in january this year, so i'm glad with my results.

       
      single frames, camera on a Baader Hyperion 13mm + 14&28 fine tune ring (so 8,2mm)

      I'm pretty new to this whole astrophotography thing, specifically the whole image resolving and stacking part. I've been using registax 6 to edit the videos, and I think I'm pretty much done with an image of Jupiter I've been practicing on from a video of Jupiter I found on the internet. I was wondering what I should do to get rid of those weird ring things around the edge of Jupiter and maybe clean up and sharpen the edges all together. Any other tips you have that could make the image cleaner are very much welcome. Thanks!

      Hi All,
      this morning i made my first attempt taking a picture of Jupiter.
      The hardware i used:
      Skywatcher Skymax 127 SW AZ GTI mount Sony A6300 T2 adapter (about 40mm long) 1,25" nosepiece on the adaptor. So camera in prime focus with no barlow, filters,...
       
      First photo:
      Camera settings in manual mode : AWB; Shutter 2,5sec; ISO1600

       
      Second photo
      AWB; 1/3sec ISO100

       
      So, as you can see not that good, a Barlow probably would have been better, but i guess there's more to be done here...
      Some tips ?
      Thank you

      I am in the process of setting up an astrophotography and imaging group just outside Filey in North Yorkshire.
      Having recently taken delivery of an observatory together with a fixed pier and currently awaiting a quote for the concrete plinth. I am hoping to break ground next month with the observatory being "functional" by the Summer.
      Please note this will NOT be a visual astronomy group as such and instead, will primarily be for astrophotography with the intent of learning and sharing techniques together.
      Lots of work ahead and this post is more of a "feeler" to discover nearby interest. I met a wonderful chap in Bridlington around 3 years ago having bought a dual saddle from him but sadly, cannot remember his name or exact location as a hard drive crash meant I lost all contact details. It is knowing someone like this relatively close by who could assist with the "little things" like EQMod, oversee the pier placement (before I cement the bolts in incorrectly), drift alignment .... ie someone who has already been through the initial stages.

      My end goal will be one of fully remoting the observatory and this may even progress to remote sessions over the internet. I do like a good challenge
      I will be charting progress in a blog on my homepage.
      Best wishes,
      Steve
      ps with huge thanks to York Astronomical Society for their help and advise getting me this far

      Hi
      My recently acquired CCD imaging kit is all very lovely, except, I don't want to keep dismantling it in order for the scope to fit back in it's case and stored indoors between sessions.  i thought I'd come up with the perfect solution, but *apparently* leaving it on the dining table isn't a viable option .  So what do you guys do?  Put up with disassembly, make/buy a bigger box, or something way more clever that I haven't yet considered?
