  1. Thank you all I am getting stars now. Got some images of Auriga last night stacked them and just about to put them through Photoshop.
  2. The Histogram is way over to the right thanks, I will experiment with the ISO. I am getting stars now, a fuzzy Great Cluster in Hercules, but not very many stars the background is washed out and I think stars are lost in the glare. Luckily I can drive out to a darker area. The camera I am using is modded, does this make it more susceptible to Sodium Light Pollution? Thinking is the orange nearer to the red end of the spectrum? I live in a semi rural area but the Local Authority, with the best of intentions for most but not me, have installed what seem to be amazingly bright sodium street lights. The whole area is bathed in a lurid orange glow. Totally ott! Thanks I will try lower ISO, and also experiment out of the glare. I was setting up in the garden for convenience with the mount bring new.
  3. Thank you both for this I will try. Sadly my result seems so white I do not have a trace of the histogram on screen. Rather I have the left hand luminance curve but no red green or blue curves. Is my set up wrong? Update! I have switched the RGB colour calibration off and I have colours. Have also followed your advice above and I have an image. Trying another now will post what happens. Thank you.
  4. New to the forum so hello all and please excuse if I am breaking protocol, putting in the wrong place etc. I am moving into tracking and can gain longer exposures now, having been using DSLR on shorter exposures using the 500 rule. As a result I am used to taking hundreds of images and stacking them. Longer exposures, new world. I have been taking 30 second exposures, perhaps 30 at a time but when I stack them in DSS I get a white screen. I have increased the star detection threshold and it has worked at times but not consistently. I am imaging with a Canon Eos 550d ISO 1600 f5 100mm fl no telescope, What am I doing wrong? What do people think would be optimal balance between exposure, ISO, etc for the brighter DSOs like Hercules cluster and the link. Any suggestions welcome. Steve
  5. Also managed Jupiter for the first time, with an Iphone 4 yesterday. Through the scope(90 mm refractor) could see two distinct cloud bands but these have not come out in the pictures some moons show up though could see four but only three came out. Very pleased with it though.
  6. Ok not earth shattering I know but got some results star trails due to too long an exposure but got the lower half of Orion with the nebula. Ended up using a feature called gradient map. best of a bunch I am afraid Before and after posted also one of the moon.
  7. Thank you both I will have a look at the free Photoshop and Gimp and will try white balance in Serif, will let you know hopefully with before and after if I make any progress.
  8. Hello very new and green I have taken images with an iPhone and spotting scope, using an adaptor. The ones of the moon have been successful but the ones of stars have the stars in the background albeit faint but are washed our by blue light , brightest in the centre fading to the edge It was a 15 second exposure and a dark sky. (Holiday Northumberland):) i have serif photo plus isit possible that to process the images to remove this all advice gratefully received Steve
