  1. This is a note in the product info section of the page you have linked: "The LRGB filters include IR-block coatings so the clear filter is necessary if you wish to image the full spectrum, including IR, otherwise you need only order the LRGB filters"
  2. Thanks for looking and the comments everyone. Yes agreed the 1st image is darker. In the 2nd image, the data seemed easier to stretch. IDK if I did exactly the same for each image, but I was more impressed with how drizzle handle the data, than using a standard stack. Like I said, I am fairly new to all the software (and AP for that matter), so I am slowly feeling my way around. As mentioned in my OP, if there are any software related books worth a read Id appreciate a heads up. I am also interested in the technique of converting a DSLR image to a (false) LRGB image by using the grayscale opti
  3. Hi Guys, Here's my attempt at M51. Not amazing, but I am pleased considering how much there is to learn. I feel I am progressing. 200p/eq5 - SW CC/1100D - BYE/Mac unguided: 13x80s ISO 800 27 darks 21 flats 30 bias Image 1: standard stack in DSS and basic level stretch in PS Image 2: 2x Drizzle, kappa sigma dark, flat and bias stack in DSS and basic level stretch in PS I think Drizzle has definitely improved the image, though it would not work without kappa sigma clipping on the darks flats and bias. I am at a loss as to why this is?? But I really dont know much about any of the software. As
  4. OK, well, I re-tried stacking, this time I used kappa sigma for the darks, flats and bias and I got a result. Yet to see if it better with or without 2x drizzle, once I get round to having a look I will post comparisons. Does anyone know why it didnt work the first time i stacked using 2x drizzle, when I didnt use kappa sigma and just had the settings as normal? Also has anyone any book suggestions on AP processing etc? explaining in depth what these settings mean, and also delving into PS too? I had a look for books but the best i could find is dated 2007. and is fairly basic stuff. I do have
  5. Hi Guys, OK, so I managed to get a bit of data Monday, only 13 x 80sec but I did a standard settings stack in DSS with bias, flats and darks. The image wasn't amazing, but I was happy with the result. I then used exactly the same subs using the saved txt file and set 2x drizzle to on. (all other settings as standard) When I got the result it was a, bright off white colour with streaks of colours all across it, clearly meaning something has gone wrong in the process. I played around in the DSS setting post stack and all that did was change the off white colour to which ever colour I played with
  6. Cheers Guys, no it would be no fun if it was easy. I also like a challenge. Just had a bit of a re-edit M51 v2 Much happier with this version

    First attemps
  8. Success!! As there are so many M51 in the deep sky imaging section, I thought I would add to this thread for somewhat of a happy ending Last night was clear, and was going to take some widefield with the 18-55mm stock lens, but the weather was better than expected so I went for the full setup. Everything went smoothly and once I was balanced, focused etc, I aligned with Alkaid and performed the same star hop as I started with, last session. (see OP) BUT this time I took 25s framing subs instead of 5s , and lo and behold I could see it!!. Think the neighbours knew it too, from the over excite
  9. Steve, although Iv been silent i have been following the progress. I still think there is something missing. I really dont think its the camera. Its something to do with the connection. But I really have stretch my knowledge on this subject and am at a loss. Maybe the CF card will sort it all out. The thing with not having sole purpose PC (how nice that would be!) is that there could potentially be a whole number of other software that could be interfering with the connection. I have many things stashed at the back of the shelf that wont connect how it is supposed to. Its how and why I have l
  10. OK, i really hate to interrupt the flow. But ( I have googled and tried to find my own answer) what exactly is sigma clipping (SC median etc) Again I am aware of their presence but I really dont know what they do. Also, although I am a bit ashamed to ask because it is mention so much, so i should know, but what is the bayer matrix? is this to do with the lay out of the sensor. Sorry to be the dumbass of the thread, but you guys are genuinely the SGL encyclopaedia of all things worth knowing .
  11. My brain has just fallen out! Cheers for the info, James. Very informative, but has made me think that perhaps I am trying to understand things a little out of my depth ATM. I am still not quite sure how much sky is an actual arcsecond. ?? I am working on it But, from you calculations and post it would seem I am undersampling, so drizzle will work and be of benefit. I know I will never get amazing images with my kit, compared to someone like Olly and most other people on here and there. But I would like to learn to get the best out of my kit, and it sounds like drizzle will aid me in this tas
  12. This is exactly how I understood the info, Olly. It was the fact that drizzle wont work with 100% aligned subs that initially caught my eye, because clearly any subs I take ATM, won't be 100%. This drizzle does seem to have a bit of grey area though, judging by some of the comments. seems quite a confusing topic even for the more experienced amongst us. So i feel like stepping back from the thread, and see what info crops up on here. Jez
  13. Cheers James. Would be interested in the calculations. Thanks for your time to do this Cheers Rik, The poster of the article I read on this subject had a whole row of pixels that were dead, and this is also how he got rid of it. I dont guide ATM. I want to learn all the bits that come before that, first, using the kit I have. But, from the posts on this thread, it would seem that, because I am unguided, It will kind of be a (bodged) dither. because I won't be able to get anything perfect. Is this the right assumption to make? Really appreciate all the help to get my head wrapped around this
  14. No harm in being keen to show your images, Scott I should probably start a new thread for this but, whats a good barlow with the (is it?) 48mm thread?. The stock one that came with the scope has the thread, but to be honest I never use it. Degrades the image way too much. Any suggestions? Cheers
