  1. Thanks Alan - my diy has improved since I started imaging but still not great! I don't need pc control so may have a look at Dave's suggestion. I did think the two I mentioned were a bit overpriced so am pleased you reinforced that. Thanks Dave am going to look at your suggestion. Annie
  2. Am looking to buy a new dew heater control - a dual one is all I need so have been looking at the Kendrick and Pegasus one, £107 and £99 respectively. Is there much to choose between them and are there any other options I might consider. I have plenty of Kendrick dew tapes. Annie
  3. Thanks for the info - looks like my next purchase! I've heard that extenders don't work particularly well but never quite understood why. Perhaps your comment about the diameter explains it. Annie
  4. First of all I love this widefield shot and also how you have superimposed the image on the star map. Thanks for explaining how you did it. Am not sure whether I can ask in this thread about your equipment? I have the FSQ106ed and the NEQ6 and have been wondering about the reducer as I love widefield - it obviously works very well ? I also wonder if the extender works as well? Perhaps admin will tell me if I should have started another thread - apologies if I should! Annie
  5. Hi Rob - Before I moved to CCD imaging I was given an old 550D Canon which I had to stick the hand grip back on! However I had it modified and it has taken some cracking images! Have fun and persevere! Annie
  6. Some good information Novi - thanks a lot. Will work through what you suggest. Annie
  7. If I want to create a false luminance channel from grayscale RGB images I usually go to channels , click on the dropdown menu, choose 'merge channels' change 'multi channels' to RGB, map the RGB images to the correct channels, ie green to green etc and everything works fine. Am trying to process my first narrowband image and would like to create a false luminance with my stacked Ha, OIII & SII subs but when I go to 'merge channels' it won't let me move from multi channels and change the number of channels from 2 to 3! Have obviously not understood something about narrowband processing and would be grateful for some help! Annie
  8. Like you I always use the handset to control the mount and was reluctant to go down the road of any form of control via a pc. However am all for making polar alignment both easy and accurate so after reading some excellent reviews of a piece of software called 'Polemaster' I took the plunge and have never looked back. What a brilliant bit of software it is, can't recommend it enough and of course it doesn't get in the way of using the handset. There are some very good user instructions written I think by Steve Richards but the on screen directions at every step are also very easy to follow. Annie
  9. Well lots of food for thought and some very helpful info so thanks guys. I think it does seem sensible to start off with the DSLR's I already have - modded canon 550D and modded canon 5D mk11 then as is suggested move forward from there. I haven't really followed what's been happening with CMOS so something to research. I would take a laptop out anyway as I like Backyard Nikon. Even in the observatory I have always used a stand alone guider, the Lacerta MGEN which works admirably so would be happy to have another. I take the point about not utilising the optical qualities of the 106 and may think about going full frame. Moving from DSLR to CCD imaging this season was a big step for me and am a bit reluctant to move away from a setup that is now working well for me however............ I am also a bit reluctant to think about setting up a mono CCD/ filter etc and associated cables outside but you never know!
  10. I have an observatory set up where I image with a Takahashi 106 with Atik 460 mono plus guider on NEQ6. I also have an HEQ5 plus a nice TS imaging Star 71, 347mm, f/4.9 which are just languishing around. As my husband is beginning to take an interest in imaging we thought we might set up outside as I did when first starting. I used to use DSLR's but now thinking about a OSC ccd. Wondering if they have sufficient significant advantages to DSLR's to warrant the expense? Annie
  11. Hope it works as well for you as it does for me. Thanks to whoever recommended it to me in the first place!! Annie
  12. Not sure whether this is relevant to your issue Jon but I had a problem with halos around eta Geminorium when imaging the Jellyfish nebula using Ha. I was told that one halo was probably off the CCD window, the faint outer one from the rear element of the scope whilst the middle one was probably off the filter! I could try using a soft edged mask to tone it down a bit but all in all was probably stuck with it! I use 2" Baader filters the Ha being 7nm. As far as I am aware if I used a narrower bandwidth I would get slightly more contrast, smaller stars so more moonlight and light pollution tolerant . but would pay a lot more and I assume maybe less likely to be parfocal. Probably entirely irrelevant to your issue!! I think we've met on another forum! Annie
  13. I couldn't get on with Fits Liberator and someone on this forum recommended Avis Fits Viewer - free, very easy to use and so far can't fault it. Annie
  14. Lovely image. That's some 'incoming'! Annie
  15. I'm an imager not an observer but found your post interesting as you'd illustrated it with a sketch. Annie
  16. Brilliant image Emil - 50 hours of data deserves a result like this. Annie
  17. At first hesitant about the extra expense of a dehumidifier in my pulsar 2.2 I wouldn't be without it now. Bought the DD1 Simple from ecoair.org as recommended by other astro imagers and found them very helpful and efficient. I equally agree with the second recommendation though mine is Laphroaig Triple Wood! Annie
  18. First of all I'm no expert when it comes to assessing scopes. However I can say that I bought the TS Imaging Star 71 a few years ago as my first scope and what a great little scope it has proved to be. I still have it though mainly use my Takahashi now. I have a very slow broadband speed so would have difficulty sending raw subs to you. I used it with various DSLR's - eg. Canon 550S, modified and Nikon D600 unmodified. No problems focusing or attaching. I sent my first subs and image to the chair of Abergavenny Astronomy society, a very knowledgeable guy and he rated it highly particularly the flat fields. Annie
  19. PS - had forgotten about Budget.astro and I do like Doug's presentations - very easy to follow so thanks again. Annie
  20. Am fairly new to CCD imaging, (mono Atik 460) and have managed to acquire 14x300 sec Lum and so far 13x120sec each red and green for the Pleiades. Mid Wales has not provided much in the way of clear nights and on the only recent starry night the clouds rolled in when I was just half an hour short of acquiring the rest of my data 13x120sec blue! I stack in DSS and process in PS cc. Am not too bad at processing nebulae and combining Ha data with RGB but this is my first attempt at a star cluster so any tips on how to process it would be really helpful. For instance after stacking do I need to do much with the Lum data before combining with the RGB .
  21. Only just started looking at this section and it's fascinatiing. Very impressive Mars sketches. Annie
  22. Fair enough - I can see what you mean by ending up with an uneven background - can I not address that in photoshop? I had been looking at Ruben Keir's book 'The 100 Best Astrophotography Targets' in which he suggests 25x120sec R & G but 45x120 sec B. It was however published in 2009 so maybe it doesn't reflect current thinking?
  23. I want to make as good an effort as possible to image Pleiades as a friend has just named her little girl Maia so thought an image of Pleiades would make a good present. I image with an Atik 460 mono and Takahashi 106, 530mm scope and have not yet tried Pleiades. I thought that 2 min exposures would be good but wondered if I should take quite a few more with a blue filter than R & G? There have been so few clear nights here in mid Wales that there's not much opportunity to practise! Annie
