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.
I tried imaging M101 here in our Bortle 5 neighborhood and it was sort of tough due to the light pollution but I think I was able to pull off a bit of data. My problem now is that I was able to increase the visibility of the galaxy through stretching but in the process the background noise also increased. I also noticed that my galaxy and stars are a bit orange/reddish compared to the other M101 shots which are kinda bluish in color. Not sure if this is being caused by my astromodded camera but I tried correcting it via Photoshop and this is the best "white balanced" image that I got.
Looking for some help in this group maybe someone can have a go with my raw file and share some techniques on how to improve my post processing. The stacking was done via DSS and the processing via Photoshop. I also used Gradient Xterminator and also Astrotools.
Here's my edit and I also attached the raw file so maybe you guys can try tinkering with it also. Also open for any suggestions or comments with my initial edit. Thanks! 😁
Light Frames: 189 x 1 min shots @ ISO1600 (yes I still don't have autoguiding) Dark Frames: 198 x 1 min shots Mount: Celestron OmniXLT CG-4 Telescope: Celestron C6N Camera: Canon EOS Rebel XT Hap-Griffin Mod Autosave.tif
this image is my 1st light using my recently acquired iOptron Photron RC6 , never used an RC before, anyway after quite a bit of trial and error figuring out which adapters were required in order to achieve focus with the Canon 600d and then getting it balanced ( quite back end heavy with the extension tubes and camera on ) it was time to put myself to the test as well as the kit.
It ended up just being a short run . the set up consisted of :
EQ6 Pro pier mounted
Canon 600d (modified)
ASIAir Pro (for the wizardry stuff)
ASI 120mm Mini guide camera mounted to 9 x 50 finder scope
20 x 120 sec lights. or ( 40 minutes in old money )
Calibration files were also used ( not to good effect i might add )
Stacked in DSS with slight adjustments then transferred to Photo shop for final butchery,
Levels and curves adjusted and cropped slightly.
Overall i'm quite happy with the outcome for such a short amount of data,
Any feedback is welcome, or any tips to help me improve with this scope 🙂
so here it is
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.
