Caldwell 9. Cave nebula47 viewsCaldwell 9 in Patrick Moor's catalogue is an emission nebula 2400 LY distant in Cepheus, imaged with a canon 200D & pier mounted 8" reflector on a EQ6 Pro mount. Guided with the Gerald made off axis guider. 2 1/4 hours Ha filter and 5 hours UHC. Bill C

Cone Nebula420 viewsAnother learning curve combining the two images. The Cone was well passed the meridian when using UHC for the star field, hence only 2 hours. The 'Gerald made' off axis guider is proving a real boon for tracking. Bill C

Crab nebula505 viewsTaken on a pier mounted EQ 6 Pro mount. 19 x 10 minute subs using a UHC clip filter. The 1100 D camera is off axis guided. Bill C

Double Cluster. NGC869 & 884299 viewsAnother try at processing this without losing stars. 9 x 10 minute exposures taken on 13th Oct 15. Skywatcher 200P on a EQ6 mount and guided with an Orion mini guider.
Processed in IRIS and Photoshop.

IC1396-Elephants Trunk Nebula269 viewsThis is the red channel Using a Ha 6nm filter. eight & half hours giving me all the info I need before combining it with 4 hours UHC filter on 28th & 29th to get the star colours. (note the triple star on the left.) Bill C

Horses Head Nebula 329 viewsTaken with a 8" Newtonian reflector on a EQ6 mount & guided with a Gerald Bramall designed off axis guider. UHC and H Alpha subs processed separately in IRIS then merged after removing the red stars in the Ha frame. Bill C

Heart Nebula321 viewsSpanning 200 light years at a distance of 7500 light years it's too tight in the frame but I could only just squeeze it in. Ha and UHC frames processes separately in IRIS and merged and further processed in Photoshop. The scope, on a pier mounted EQ6 is guided with a orion guide camera fixed to a Gerald Bramall off axis guider.

IC342 The hidden Galaxy16 viewsThe galaxy, at over 20' diameter and around 10 mly distant would be prominent if not hidden among the stars, gas and dust of the milky way. Over 7 hours of exposure without a filter in Dec 19 added to over 4 hours with a UHC filter in 2016. I found it difficult to process due to its faintness.

Leo Triplet186 viewsThe Leo Triplet includes NGC 3628, Hamburger galaxy. About 35 mly distant. The light reaching my camera started out soon after the demise of the dinosaurs.
Just over four hours exposure using a UHC clip filter on a EOS 200D camera on a skywatcher 200p reflector.
