  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
  9. 3 images captured on Sunday evening. There are two of Orion as I couldn't decide which processing result I preferred! Thanks for looking Barry Bubble Nebula Monkey Head Nebula Orion Nebula and Running Man Nebula
  10. Thanks Simon. It is a DSLR image from a 600D on a SkyWatcher 150P/HEQ5. 36 x 180sec. Guiding was by PHD2 with a Finder Guider. Barry
  11. My best effort so far, imaged in a surprise clear evening last night. Barry
  12. Does this mount also do basic panning between user added positions for terrestrial photography and time lapse, in a similar way to the SW Merlin Multi Function Mount?
  13. Hi, I have a retired SW Equinox 66 that has a very graunchy focusser. Would this be of any use? Barry
  14. Hi I did a really silly thing on Friday night by leaving the ISO on my 600D at 6400 after taking a quick image to align using Astrotortilla. The resulting image from 12 x 600s subs is attached. The thing that has worried me is that there are some odd vertical lines on the left of the image, about 3/4 to the right. Could this be because I took 10 min subs at ISO 6400, or is it a problem with the camera sensor or internal reflections? The lines can just be seen on individual subs at ISO 6400 but not on 5 mins at 1600 subs or on 10 min darks at ISO6400. I have just bought the ca
  15. I found some shame and reprocessed M27! After the excitement of capturing, the processing can be a lot harder. Barry
  16. Hi, Here are 3 images from last night taken as I tried out some new kit. Shamelessly overcooked to bring out data! Thanks for looking Barry Albireo Deer Lick Group and Stephan's Quintet I nearly missed the Quintet altogether through misframing but they are just there on the edge. Far too little data but I was happy just to see the fuzzies. M27 - Dumbell Nebula
  17. Hi Tom, I checked the weights this morning. They are the same size and bore as my HEQ5 weights (5Kg with bore 20mm one side and 25mm the other) but without the plastic sleeve. They lock on securely to the HEQ5 bar. I also tried the HEQ5 mount on the tripod; apart from the colour I think it is identical. I live in Netheravon, which is off the A345, about 5 miles north of the Solstice Services and Countess Roundabout on the A303. Monday 11th is fine for me. I will PM the details. COD is best so you can give the tripod a check over. Barry
