I've just had a Canon EOS 250d modified by Juan, IR filter off and shim to restore focal plane.  He previously did the same for a 100d which got me going in the hobby.  Juan is willing and able to take on successive generations of camera.  I prefer to rely on Juan's experience for this task, despite me being an optics specialist professionally.   The cost of the camera and Juan's conversion service together are a bargain and I trust him with a new camera.   

I like to use this type of imager over the specialist cameras because they are the result of Canon's massive R&D capability and bundle together all these functions:  battery, an up to date sensor chip, the on-board software, on-board storage, built-in display, easy-fit Astronomik filter. In the case of the 250d, that very important tiltable display so you don't have to crawl around on the wet lawn to see it.  The only thing they don't have is an easily-implemented thermo-electric cooling.  But I've got a long way to go in astro-imaging before I care about noise that much (though I'd like to cool, and understand what can be achieved, I use stacking averaging in the meantime to go part way in that respect).

The dslr is my one imager for three rigs, the most notable being that it's lightweight enough to go on my Omegon clockwork mount. 

On my heftier rig, I do have an Altair camera with a Sony back-lit chip but only use it for tracking with a wireless-controlled Stellarmate setup, having got fed up with all the cables and tablet pc with memory dangling off it.

      HI
      Does anyone have any idea what the grey smudgy area in the centre of the image could have been caused by?
      It appears on all the images of the Leo triplet,  taken on my modded canon 250d.
      I have checked the sensor and its clean, and collimation was confirmed with a laser.
       
      Condensation on the secondary mirror?
       
      Skywatcher 300PDS, X0.9 coma/reducer and the canon.
       
      Thanks

      Finally built a peltier cooler for the canon 600D. Credit goes to Martin Pyott for the originl design:
      https://www.youtube.com/watch?v=LVrTpCn1MhA&list=WL&index=1
      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.

      This is a lens that does not need an introduction, it's simply a fantastic budget lens! I've been using it for astrophotography with great results and satisfaction (see pictures). Just selling it becuase I'm upgrading to the 135mm version. Any questions please ask. Asking £160 which includes P&P to UK mainland.

      I took this photo on multiple nights, between 19th February and 15th March 2021.
      Imaged using my cooled and full spectrum modded Canon 40D DSLR attached to a Bosma 80mm f6.25 refractor on a CGEM equatorial mount.
      Total exposure time was 22 Hours and 1 minute using 7nm HII, OIII and SII Narrowband filters and stars are from natural color (UV/IR Cut filter) subs... imaged from a semi rural sky.
      HII: 6x600s, 6x900s and 4x1200s subs,
      OIII: 10x900s, 8x1200s and 1x1800s subs
      SII: 18x1800s subs
      RGB: 19x60s, 19x120s, 18x180s and 20x300s subs @ ISO1600.
