  1. It might be the darks in number 1. Dslr darks can add noise I keep reading and my own basic imaging they do, I think try number 1 with lights flats and bias.

    Thank you for sharing your photos. I am always interested in other people's barn door trackers. Mine currently is manual I turn a handle. I don't know how to code Arduino but found an existing code for a barn door tracker so will be copying that when I motorise my existing build, I have all the parts but missing a cog to connect the motor to the other drive cog, I will have to fabricate something for there when I get around to it. When it is all working will be the fun of trying to get the code right to give 1rpm. I hope you can work out why you are getting .56rpm
  3. It must still have been quite dark location as that looks a lot of image for 6 frames, nice capture.
  4. For me L + F + B + MBasMD does as it fits the time I have available where darks would otherwise add noise.
  5. Astrophotography help

    The d40 with the widest fastest lens assume your 52mm. M mode, d40 is not full frame sensor so you can take exposures 7 seconds long before star trails. Point at the milky way. Make sure tripod nice and steady, take practice shots to get focus right. Probably use around iso 800. You are looking for the histogram peak to be clear of the left hand side but not as far as the middle. Once focus is good make sure to either use a remote release or the self timer. Take lots of photos using raw ideally. You can then combine them using 'deep space stacker'. You can do basic processing with that software as well. Take lots of images say at least 10+. As you learn more you can do calibration files. I think the biggest initial hurdle is can dss read the raw files from your d40. If there is any in camera noise options turn them off. When you take a 7 second image it should just be 7 seconds if it is longer there is some noise removal stuff going on.
  6. You could go visual to start FLO I think do a 150pds with az4 bundle, then keep an eye out for a second hand heq5 synscan pro for your ap mount thirst. You don't have to have a tracking mount to image Moon or planets as that's best done with video clips.
  7. M32 Andromeda Galaxy Wide Field

    I like budgetastro.net Doug covers dss and Photoshop but it's pretty much all possible in dss and gimp.
  8. Alt Az not tracking

    Need to see an image really. For example if the stars are streaking upwards then you are tracking but in azumith only and not tracking in altitude. Check balance if that is the case.
  9. A guide for astro-images?

    Olly the OP already owns an EQ5 hence the comments but with suggestion to read the book which I also gather they already own.
  10. A guide for astro-images?

    link here Kit lens imaging.
  11. M32 Andromeda Galaxy Wide Field

    Nice framing. Did you stop the lens down much?
  12. A guide for astro-images?

    Start with your kit lens I'll add a nice article to read about imaging with the kit lens later today. Then read up on lenses some vintage are better than others a m42 fit asahi super takumar 135mm f3.5 are nice. You might even have family members with a lens you could borrow, charity shops can also yield nice old lenses. M42 to eos adapter about £10. The idea is to buy as little as possible whilst you see if you like, read research more, and read that book.

    Aperture is about observing because the eyeball captures only so much light, imaging is about exposure time which is what gives the light.
  14. A guide for astro-images?

    You'd be fine if your camera has an lcd all the easier particularly if it is a flip out one.
  15. A guide for astro-images?

    Here's the fov canon 1100d with a 50mm or 135mm camera lens.
