I do not know whether this is the right place or should I put this question in other section.
I am into Astronomy since last 7 years and currently planning for a few Astronomy outreach activities in my region (India), specific for rural/underprivileged schools and colleges, which might require funding from local govt.
But, everywhere, I get one specific question that "what is the use of Astronomy?" And I can't just give generic answer like science popularization etc. So my question is, are there any research work, statistical work done in your region or that you know of which look into impact of Astronomy at school-college level students, like improved academic performance etc.
e.g. International Astronomical Union page mentions that exposure to Astronomy at adolescence years gets more students pursuing science and technology as career.
When I visited San Jose, US, I saw way more planetariums compared to the size of the city. Here, we only have one mainstream planetarium, even though it is quite large and active.
As long as what I am seeing, many European countries have many active Astronomy clubs compared to the population and maybe that's why there is more exposure for the students.
Thanks in advance!
I am not writing any paper or something, just want a concrete answer to why should we show the stars to others.
For sale 450D camera modified for astronomy, the IR filter has been removed to allow the important red emission nebula to come through. The price is £140.
This camera has a very low shutter count of 1588, in very good condition, comes with 1 battery and charger (connects via USB to computer or smart phone socket ect ), I don't have the original box, but will pack, very well. The price includes special delivery. This is for the camera body, no lens. Any questions please email me any questions......clear skys.
Finally built a peltier cooler for the canon 600D. Credit goes to Martin Pyott for the originl design:
I had to modify the design slightly due to the aluminium plate snapping and a comedy of errors on my part, such as not being patient enough in drilling the copper plate and snapping a drill bit in the hole.... all learning experiences.
I was going to invest in a dedicated OSC astro camera but this will allow me to get a bit more milage out the old faithful DSLR. I have attached photos of the finished project and Darks (10 min at ISO 1600) and was impressed and surprised at the difference this mod made in noise levels. The cooler managed to drop 7 degC on ambient after running for about 15 min or so. I don't know how cold it will get when running for longer, and know it wont be able to compete with a dedicated astrocam, but any cooling is a bonus, right? At about £35 for the parts this saved me a fortune which will go into the dedicated TEC cooled mono camera fund.
Next on the DIY list are a power box (with power for the mount, camera, dew heaters and RPi: I have already made my own 12v power distribution box which sits on my EXOS2 "portable" mount) and a couple of auto focusers using the MyfocuserPro2 project on sourceforge (the parts are winging their way to me as I sit here). The savings bring that dedicated mono camera all the closer 😀.
Any advice from anyone who has made these projects very welcome (maybe it will help me avoid more silly errors) or ideas for other projects too.
Clear skies 💫
This is NGC3603 and NGC3576 (AKA The "Statue of Liberty" nebula), a massive H-Alpha region containing a very compact open cluster, located in the constellation "Carina" about 20,000LY away.
I took this photo during two nights, 14th and 15th March 2021. Imaged using a active cooled and full spectrum modded Canon 40D DSLR attached to a 80mm f6.25 refractor on a CGEM equatorial mount.
Total exposure time was 3 Hours and 31 minutes in natural color through UV/IR Cut filtered subs from a semi rural sky.
RGB: 19x60s, 19x120s, 18x180s and 20x300s subs @ ISO1600.
