  1. I know that it should be like that and have no trouble with my Newtonian with two mirrors to align, but when I tried to do the same with the SCT in the dark with my screwdriver perilously near the corrector plate it didn't work out so well. At the time the star I was using also refused to stay in the middle of the fov, which didn't help, I am happy to leave the dark art of SCT collimation to those who know what they are doing. Barry
  2. Lockie: Yes it is cheap and deliberately so. I bought it secondhand some years ago as part of a bundle which included a mount I wanted. I am much happier at F5 than F10 and could not get my head round how to set this up. I think that I effectively dis-collimated it and so a new owner has some work to do - hence the price. Barry
  3. John The last session I had was a year ago - which is most of the reason why I am selling my kit. I have attached one sub from that and also a pseudo flat frame take this morning (no lens 1/250 shutter) which should show that the sensor is clean. IMG_0030_1.CR2 _MG_3401.CR2
  4. Asad I am not willing to post the C6 but if it works for you I could meet you halfway, say at Cobham Services? That way you could check the scope over first. Barry
  5. John I would prefer not to post because I would like the buyer to inspect the camera before committing to buy it, but you are probably too far away to do that. I can pack and post it safely but you are taking a risk buying it unseen. Barry
  6. Highburymark - I am now splitting (I didn't last very long on that one) I have added prices to my original post. Barry

  8. This image of the Leo Triplet was taken on 25 Feb using a Skywalker Skywatcher 150P (without a Coma Corrector) on an HEQ5. The camera was a modded Canon 600D with an Astronomik Visual CLS Clip filter. Guiding was with a QHY5l II and SW 50mm Finderguider using PHD2. 16 x 360s subs were stacked in DSS and stretched in Photoshop. The 25th was not the best of nights for DSOs due to a very bright moon and the gradient remains! Thanks for looking Barry
