  1. Thanks Rodd. I admit having to go in close to see what you meant but I see it now. Something to remember for the future when checking images
  2. Below is my SHO version of the Cygnus Wall in the North American Nebula. This was my setting up image at PixelSkies and was taken between 24-30th July with an APM650/105 and an SX H694 camera. The image comprises 51x600" Ha, 28x600" O111 and 21x600" S11, entirely processed in Pixinsight barring a final tweak in Gigapixel. Obviously the region is commonly imaged though this is my first attempt at this specific area. I made the conscious decision to retain a little of the green and not go too blue purely because i preferred the final result. Thanks for looking.
  3. I have had two goes at this very feint object over the last few months, once from home in limited skies, and once from my remote imaging setup at PixelSkies. I'm sure you can guess which image came from which location. Home - four hours of Ha and O111 data, plus some lum, all form a widefield setup PixelSkies - eighteen hours of Ha and O111, from a medium focal length setup, plus consistently darker skies The home image was challenging in that despite being at a much higher altitude, my sky was just never good enough for such a dim object and whatever the rights and wrongs of processing, there really is no substitute for dark skies and time. thanks for looking
  4. this is light years ahead of my effort! great result for your dedication
  5. That's quite an effort from sun-kissed Grimsby, and dedication to a long term project!
  6. I would be spending some time in the classified section here, or at https://www.astrobuysell.com/uk/browse.php In my experience the vast vast majority of second hand kit is of very good quality and the vast majority of people who sell would declare any imperfections anyway; i would be more cautious about placing a 'wanted' ad and always try and speak to someone on the phone before parting with any money but this may well be your fastest way to find what you want with some longer nights being more apparent now
  7. With clear nights still forecast, you can still take your subs while you figure out what has gone wrong; then you will have lots of processing during the next lot of clouds This does look like an over-correction and to me looks like an overcorrection of the flats, at least with the above that’s where I would start, temperature differences??. When I struggled once with calibration I used the trial version of APP; changing software made me rethink what I was doing. What I liked about APP was you just throw everything into the same folder, let it sort everything out while you enjoy the sunshine before you pick up the result. At least you will know if you can get a result with your existing data before you spend ages taking more. If you use the old calibration files first and then compare with a new stack recalibrated with the new calibration files you can start to tie things down with existing files, swoping different old/new groups in and out etc. I often create a raw uncalibrated stack, ie a baseline right out of the camera. Sure there will be vignetting etc but assuming it is better than above, you have removed the camera from the list of possibilities. If things were working, why did you update the calibration files? Unfortunately I dint think there are shortcuts here.
  8. A very big thank you to all involved in StarGazine as the work, hassle and time involved must be significant. This has been a very successful series with many of the talks ranking as excellent, including some topics I never knew I didn't know . For me though, this has been via the YouTube followups as Sunday evenings are no use to me. If there is a desire to keep going and live attendance is the main driver, moving the day or reducing the frequency might work. However I suspect the YT option, being the most convenient, will always be best for most. Maybe then the question becomes, do you want to commit to a wider YT channel and how to stand out? Specific talks have a lot more interest than general 'society' aob, but that's just mho.
  9. Not yet. Voyager really is the complete package, though I have found it takes some learning. The focus routine is so much better but for me the real seller is the fully integrated array system. Mosaics are probably easier in SGP as it is within the programme whereas the only way I have found to work this in V is via their web access tool which drops the mosaic settings into Roboclip (in V) though that may be my lack of practice. You get 45 days full use as a trial, which for you in Spain should be plenty time to find the functionality you need
  10. Hi Peter, if a computer numpty like me can make it work I'm sure you will have no trouble. Like everything, it is the initial setup that makes everything else happen and Voyager is no exception. The array aspect needs both scopes/cameras etc setting up individually in their respective Voyager programmes and then the primary system (the one that controls the mount) has additional settings that directs the array to the secondary system. I have them on different computers but I believe that isn't necessary (though certainly simpler). The primary system is put into array mode and is linked to the secondary. From there, nearly everything you do in the primary system is mimicked in the secondary though the two sequences can be different. In answer to your question, yes, the secondary/slave stops imaging and the primary takes over, pushes the mount to flip, plate solves, and re-initiates the imaging again. I am still baby sitting this manually at the moment but am getting braver about using dragscript which will mean once I ask it to go, everything should work on its own from there; except my roof motor still does not work so I have to be available for manual closure. The attached picture is from the widefield array but you get the idea. So far I am really impressed with this programme, and the backup, and since I am more or less out of astro dark now, I intend to learn what I can over the summer especially developing and using dragscript for all functions.
  11. If you can, have a listen in on the Stagazine on Saturday - I’m sure there will be plenty at this meeting. Adam Block has a few YouTube videos on the same subject and I can say that after following his advice, my calibration is a lot better.
  12. can't help directly as mine is a usb version, but Phyllis Lang at Knightware responded to me over the weekend with my query about COM ports; i have always found her to respond very quickly and with a solution so I would probably head onto the Knightware site for her details
  13. After various delays, i just completed my first test array sequence in near enough full moon (of course). It all worked fine and am feeling quite happy with myself at the moment as i usually find some way to mess things up. With much to learn, I still have a very manual approach to this software but so far so excellent. I am quite a bit off any real automation, not least my roof motor doesn't work at the moment, though this remains my ultimate goal to achieve this year. Leonardo will dial in some time soon and I hope send me in the right direction re Dragscript and some basic automation etc. Despite this being another world for my very non-computer orientated brain, i can see huge potential with this software and will continue to get used to where options and services live. As @sloz1664 the safety elements of reliable closing in bad weather, and reopening should clear skies return are worth a lot to me. Hopefully i can now think about consigning SGP to archive
  14. Taken from Pier14 at Roboscopes in Spain, this is a blend of two different processes that started as SHO and HSO though i wasn't particularly pleased with either. Pier 14 is a ZWO6200 attached to a Tak FSQ106 approx 35 x 300" H, O and S frames were used in this image and this is a crop of the central region thanks for looking
  15. Any chance it still might be dew? I know you said you have a heater and a shield, but I have had some weird artefacts on subs before which sorted once i realised i had messed up the dew control
  16. thanks Alan; this was definitely an experiment in osc for me so maybe and i was surprised at the results so maybe i should try again? I have my resolution on this at 7.6"/p compared with my home widefield running around 2.7, but i think it far more likely to be me that is missing something as i cant see any structure - i plate solved just to check, though the larger stars look right
  17. As much as I want to take my own images with my own kit, this winter hasn't been brilliant for anyone so i have gone with Roboscopes in Spain for a year to see how i get on, and still try to use my own kit as much as possible! At least i should get some processing practice which is very necessary. There is plenty choice of what system to use, and therefore target, and since i hadn't even used osc, i thought why not. This is my first osc image and was primarily an experiment for myself so i deliberately chose a star dense field just to have a try. The "kit" is from Pier 4 with the Sigma 105 lens and the ASI2600MC camera and is 84 x 300". Thanks for looking
  18. At least the obs is getting some use by something at the moment. Not sure how warm it is but i think the hard work of the birds responsible will not be disturbed
  19. Being in the same situation, like you, I went down the multiscope rig route so at least data is acquired at 2 or 3x the rate and therefore grab what clear opportunities arose. The main advantage is that data *is* acquired at 2 or 3x faster so in theory you should halve or third your target time and projects do get completed ready for processing. Reality for me is that I then revert back to something Olly told me once which was 'data is king' so I tend to acquire much more on a particular target than I normally would, so where is the advantage when there is an obvious £ disadvantage? For me at least astroimaging is also about the build and the challenge of making it work. The Problems Squared Rule definitely applies though. However, when it works , then you do get to see where you stand in processing terms, and I have a lot to learn! In addition, rather than ship some kit to Spain, which would seem a foolhardy exercise just at the moment, I have dipped my toe into the world of Roboscopes, a kind of pay-as-you-go imaging enterprise. We'll see where that goes but given just the £ cost per image from UK it seems good value, but that doesn't give you (well me!) the satisfaction of achieving something totally myself. So for mechanical processing of your own data it seems fine, as it is your own data (you chose and paid for it) but I'm not sure I'll get the satisfaction. So I persevere with UK astroimaging despite the problems and perhaps just because of them as well .
  20. This ended up being a tortuous experience which i wouldn't let go. Ultimately over (too) many evenings, this is a four pane mosaic of LDN1495 taken with my multi-scope-wide-field rig which was pulling in three times the hourly rate of data. Approx 50 hours of Lum data and 40 hours of RGB were used to tease out some details. These totalled - L - 132x10' and 160x7' and 128x6' R - 271x3' G - 264x3' B - 264x3' This may seem excessive and it is. However i managed to not have enough data to reliably stitch the top to the bottom and had to reshoot a central strip so i guess if i had managed this first time around it would average at 15h LRGB a panel which is less excessive . I normally use Pixinsight, but i just couldn't make the mosaic processing work this time and in the end used APP for stitching the raw frames together, and then moved back into PI. This was my first time using APP and what a great programme they have produced so will look deeper into this in the future. LDN 1495 is a large dark nebula that dominates this field of view though there are other objects including LBN782 (Cederblad 30), vdb27, B7, B209, B216 and a few background galaxies hiding in there as well. Thanks for looking.
  21. What an excellent image and you didn’t take long to use them . Zoltan’s loss is definitely our gain with this quality, though I’m sure he will have a queue of customers. Hoping for many more
