  1. This is a high ISO image comparison with a number of current DSLRS. http://www.dpreview.com/reviews/image-comparison?attr18=lowlight&attr13_0=sony_a7rii&attr13_1=canon_eos6d&attr13_2=canon_eos5dsr&attr13_3=canon_eos7dii&attr15_0=raw&attr15_1=raw&attr15_2=raw&attr15_3=raw&attr16_0=12800&attr16_1=12800&attr16_2=12800&attr16_3=12800&attr171_0=on&normalization=compare&widget=1&x=0.5898791540785498&y=-0.14580658783783781 This gives the canon 6d a run for its money. Even for ISO values close to 12800 the image quality is something t
  2. Sony have now confirmed that they will support lossless compression for their RAW format. Which is a bonus for astrophotography. Sent from my iPhone using Tapatalk
  3. This mirror less camera seems to have some very interesting features. Including a backlit CMOS sensor, huge ISO range. Rebinning for video at least for 4K and a 120fps for standard HD (720p). This could be an interesting planetary camera and for low light video. Not sure if rebinning will be made available for standard images, that would make a great all round camera. http://www.dpreview.com/articles/4329110043/alpha-dog-hands-on-with-sony-a7r-ii Sent from my iPhone using Tapatalk
  4. Lovely image great colour Sent from my iPhone using Tapatalk
  5. The native canon software does a good job of basic levels and processing of raw. Also it is possible to convert to tiff if required. Sent from my iPhone using Tapatalk
  6. Hi Welcome to sgl. Hope you get over the teething troubles with the scope. Try setting up the scope AWAY from the SUN on a cloudy day to check your focus. You can get some great images even in light polluted London skies. Sent from my iPhone using Tapatalk
  7. Great comparison. I guess your scope is well collimated? Sent from my iPhone using Tapatalk
  8. Absolutely awesome. Apple will want to buy you out ! Sent from my iPhone using Tapatalk
  9. Great image from a 6se. You have pushed it to the limit there. With sharp cap I have found recording frames in mono (taking the saturation right down ) really helps remove the chromatic noise. Using this as a luminance channel then recording the colour frames. Will try to post some results on this soon. Sent from my iPhone using Tapatalk
  10. Great image from a 6se. What camera and optics did you use? Sent from my iPhone using Tapatalk
  11. Very nice kit. That scope has some serious engineering. Thanks. Sent from my iPhone using Tapatalk
  12. Hi I have found an interesting transformation tool in a mathematics package called Mathematica (a phenomenal piece of software if you are so inclined) one can transform the colour balance of any image to a target format with one line. I have posted the technique in the imaging techniques sub forum if you are interested. Sent from my iPhone using Tapatalk
  13. Thanks for the tips. Will try that out on my abysmal m31. Sent from my iPhone using Tapatalk
  14. I regularly use my 6se for planetary and lunar imaging. I have used it with small sensor web cams as well as my canon 1100d. The little web cam is not easy to get the image in frame first time but I found an ep that is parfocal with the webcam (or near as) and do a quick swap once the target is aligned. Most if my images are taken with x 3 xcel Barlow that dies the trick and I have even images at x 5. This required a steady hand on the controls to keep the target in frame.
