    I stand corrected!
  3. USB3 Laptop solely for astro-imaging - decision time!

    I buy reconditioned Lenovo machines from Amazon - the previous two have been reasonable high spec machines, that are easily expandable, and rugged as heck which is good for outdoors. Often, the machines have had light / no use at all and have been sold off in bulk by IT departments. My next laptop will be another one of these, with 3.0 USB ports. As an example (and just one of several) ... https://www.amazon.co.uk/Lenovo-ThinkPad-Professional-Certified-Refurbished/dp/B01H5NW8YA/ref=sr_1_9?ie=UTF8&qid=1506689756&sr=8-9&keywords=lenovo+usb+3.0+laptop

    Forecast looking pretty decent tonight - fingers crossed for some galaxy work.

    If it's Canon, select RGGB as the bayer pattern in DSS to make sure as I've had auto fail sometimes.

    I never use bias frames - they certainly knacker my CMOS frames (introduce amp glow rather than help calibrate it out) and, as my DSLR is also a CMOS sensor, I don't use them. I do use darks and flats and they seem to work ok

    Thanks for the comments Wakefield has some of the worst light pollution in the UK (surrounded by other major towns / cities plus the M1 / M62 motorways. I use a CLS filter in my DSLR (just bought a CLS CCD 2" filter to notch some more LP bands out), and also stack a lot more images - this is 100. To draw out the data, I used a series of masked stretches that allowed the outer spirals to be stretched while progressively protecting the core. The most important skill I have learned was how to use masks in processing.

    That makes sense - I had thought I had dithering switched on in BackyardEOS but it might not have been working, or not as strong as it needs to be. I don't get any streaking when I image in SGPro. Thanks!

    Sorry I missed (yet another) meeting - but it was the only clear night this week and I wanted to get some first light on a newly modded DSLR. Also I really wanted to get onto Andromeda Galaxy as it is the reason I first became interested in astronomy. Anyway, here is my M31 M31 Andromeda Galaxy by Jay Bolt, on Flickr
  10. M31 Andromeda Galaxy

    This is first light on my newly modded Canon 100D, taken from my light polluted backl garden in Wakefield. It's been 6 months since I began imaging and I'm pretty chuffed to finally get onto Andromeda. I do have an issue with some odd streaking (zoom on on a border on the spiral or in the background). I get also get it on my Altair 178c and on all my scopes so I can't put my finger on what is causing it other than light polluted skies - any ideas? 100 x 180secs, 30 darks, 20 flats M31 Andromeda Galaxy by Jay Bolt, on Flickr

    It's dry now It's not the first time ...

    Damn weather forecasts - metoffice showed me clear through to 6am so I went to bed at 1am, leaving it imaging. Must have started raining at some point after that ...

    I'll help where I can!

    Well, I left mine out all night and by this morning it was soaked!
