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! 😁

I wasn’t able to get out to the park last night but once the smaller of the children was abed & the teenagers uploaded to their games I popped on a hoodie (cunning anti-security light plan) and decamped to the garden, wine in hand, for an impromptu after dinner tour with the ST80.
After wrestling with the old wooden tripod on my “new” Prinz 330 60mm earlier in the week, the Manfrotto 55 and full height viewing position made this feel quite the luxury experience!
Wide-field views weren’t bad either...
15.4, 9.30 PM
ST80 & Baader Zoom.
Seeing good, transparency patchy at Zenith, murky below 30 degrees.
Castor - almost split @50x low over rooftop
M44 Beehive - great view, put the red dot right on it. Was above the houses & enjoyed the soundtrack to a neighbour’s party whilst lost in space.
Melotte 111 - lovely view. Super round pin points & some good colour contrast with white & a smattering of orange stars. ST80 loves these slightly fainter clusters. No hint of CA. This cluster now firmly on my highlight list.
Chertan & 73 Leonis - but no triplet (well it was worth a try)
Algieba - Split (just) at 50x, nice yellow headlights.
Had a look for anything apparent in the Virgo galaxy field but lots of white LP to SE so no chance.
Cor Caroli - beautiful view in the ST80. White primary with smaller fainter white secondary - nice round stars.
Mizar - again a super field, Mizar A&B look a close pair at 50x with size contrast - easy to imagine as an orbital system. Alcor a way off and a couple of other faint stars making a nice little asterism.
M81 & M82 - yes! From the garden, a first outside of M31! Hoodie over the EP. Dropped the red dot carefully in line from the diagonal across the bowl of the plough/dipper. Galaxies popped with a slight nudge from original guess. See an oval and a stripe & that fantastic orientation - obviously no detail but a rewarding view from among the security & streetlights!
Enjoyed for ages with a glass of wine!
Civilised galactic travel...
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
