  1. 34 2-minute subs, no darks. Exif says 6c so the sensor was probably somewhere between -15 and -20C! Begging for a few more hours!
  2. This is my ISO1600 data from 2016 (31 60s subs) plus new ISO800 data (32 120s subs) from last night.
  3. Last night was one of those unexpected clear nights; I had assumed the scattered cloud would spoil everything - in fact I lost ten or a dozen subs once or twice, but the mist was concentrated into the cloud and in between it was nice and clear and steady and despite the LP at home things went quite well. Let's see what did we get? First, 20 minutes on M15, just to wait while my real targets rose a bit higher. I like this because you can make out isolated blue and yellow stars in the gobular. Next, the nebulosity around Gamma Cassiopeia, just 34 minutes as about ten subs were lost to cloud. Really a test as my last attempt on this one didn't show any nebulosity: Sixty-nine minutes on the Wizard Nebula. It must be bright as it was clearly visible on each sub using the preview screen. I was going to do two hours but didn't allow for a branch 40-feet overhead: One target I keep struggling with is M33, the Triangulum Galaxy. I got two hours of data and also used half an hour from three weeks ago. It didn't show up in the previews so the framing is a bit off: Finally, the Plieades, 46 minutes before the sky started to lighten, plus about twenty from earlier in the month. No doubt I will revisit these several times, but it was a much more productive session than my last dark sky attempt.
  4. Please help!! As said in the title I know that this question gets asked a lot of times. I want to know what to do. My confirmation(don't know if that's what you call it in English) is in 59 days, and I need some help whether to wish me one thing or another. What am i looking for?: I want to get into "serious" astrophotography, however I still don't want to stop doing visual. I have a scope now that needs to get swapped out(bresser 150/1400, poor quality) but I don't have the money to have both a scope for astrophotography and visual. I was thinking about the star adventurer mount(I have a nikon d3300+kit lens and 50mm 1.8+a sturdy video-tripod) because of its easy setup and portability. Then I could put a skywatcher dobsonian on my list as well to get a better visual scope. I think that this would be a good way to start, but I am 14 years old and I don't have the money to buy equipment all the time. So the problem in my case would be that I wouldn't be able to afford a real mount and scope for astrophotography right after I get the star adventurer and a dobsonian unless I save up money for a long time and get broke right after buying the equipment. This leads me into my next "solution". Then I was thinking about selling my visual scope and putting the eq5 pro on the list instead. Then I don't know whether to chose the 130p-ds, 150p-ds or the evostar 80ed to go with the eq5 pro. I am really blown away by the quality and images by the evostar 80ed, and I think that it's a really good beginner astrophotography scope. Or is it? It costs a lot more than the 130p/150p-ds does, and the reflectors would also be a better visual scope wouldn't they? of course I still want to have a visual and an imaging scope, but if I chose one of the reflectors then I guess I wouldn't need both right now, would I? I want to make the right choice both mount and scope, and if the evostar 80ed+eq5 pro is the best choice then according to you, then I would just have to buy a dobsonian as well(which wouldn't be that big of a deal if just the evostar 80ed+eq5 pro is the best choice). Hope that you want to spend some time reading this, and feel free to ask me about anything! Victor Boesen
  5. I'm starting up this thread with the aim of completing my first image of the Orion nebula [M42]. I will be building upon the image as the thread progresses, hopefully some of you will follow the progress and offer your suggestions and expertise as I go Background information I have been allocated some wall space for some pictures, albeit in the downstairs loo. We all got to start somewhere though right? Now that isn't as bad as it seems, every guest that comes to our house usually finds themselves in that room at some point so I'm maximizing the viewing potential at least... My partner has also granted me permission to purchase a CCD camera to help me improve on my 'good work so far' All of these things have led me to be a bit more focused on what I want to achieve. Usually I set my equipment up and then flirt between different targets during the night. It has become apparent that I need a single target to expend my efforts onto and I decided that the oft imaged Orion Nebula should be my choice. I don't have a lot of DSO imaging experience having finally acquired enough gear in July. Planning stage The plan so far is going to be gathering data with my newly modified 450D and 130P-DS. A CCD will surely arrive at some point but that decision requires far more research and decision making before I take the plunge and part with some ££. Last Friday I managed to get 40 minutes or so practice time on the target during a break in cloud. The modified 450D is so much more sensitive than my normal 1100D, it really surprised me. My usual 10 minute subs were Destroyed by light pollution. I'm able to guide up to at least 15 minutes so its a shame that I don't live in a dark site. Whilst my other half will stretch to a CCD, I don't think a house move is quite on the table (yet ). I decreased the exposure time down to 6 minutes and got something a lot more manageable. I could only complete four of these subs before cloud forced me to pack up so I didn't run any dark calibration frames. I Stacked the four images in DSS and I can see some potential already: My initial aim is to complete two stages for the image At least one hour of short exposures for the core. I'm unsure on whether this will be 60 or 120 seconds at ISO 400 or 800 (any suggestions?) At least two hours of long exposures for the surrounding nebula (20x6 Minute exposures at ISO 800 which I think is going to be my max with the light pollution I have around.)My setup for the start at least will be: Scope: 130P-DS Camera: Modified 450D Filter: SW light pollution filter Mount: HEQ5 Finder Guidecam: QHY5L-iic Lastly, I was unsure of where to place this thread so feel free to move it if you deem another area more suitable. Hints, tips and criticism is always welcome Regards, Rob
  6. Quite like this! Easier to process than the Heart and Soul!
  7. Ladies and Gentlemen, With the assistance of my good friend 130P-DS, I offer you this as proof that the NEQ3-2 Mount can be used for astrophotography. What DSS says are the best 80% of 87 60-second subs (proving you can get plenty of usable decent-length subs with the EQ3) at ISO 1600, astro-modded Canon 450D. Also my first use of a £10 light pollution filter off eBay and the first image I haven't had to do ANY gradient correction on at all. (Can you tell I'm chuffed - even so I know it's not perfect, I expect to keep coming back to this and reprocessing it for a month or more and constructive advice more than welcome).
  8. What a difference a dark sky makes! I knew I could get the blue as well as the red bits out of the Veil but a dark sky and reasonably cool night have let me get an image with rich nebula colours and nice stars too:
  9. They said it couldn't be done! I won't pretend this is perfect but it's 90% of 106 2 minute subs on as astro-modded Canon 450D DSLR using an EQ3 mount at a suburban location, and the transparency last night was poorer than the previous evening. NGC133 and its dust clouds are NOT supposed to be the sort of target you can get with this kit. I know it isn't perfect and doesn't stand up to images with double-figure hours of narrowband subs, but it does have the dusty bits in the right places if compared to Olly's recent image. If I had 20 hours of subs at a dark sky site what would this image be looking like?
  10. My apologies for the noise on this image, my excuse is that this is 80% only 31 frames (120 secs, 800iso, 130P-DS) taken with the moon up and haze increasing before a complete white-out of cloud this evening. My first session for exactly two months! Rotten shame about the noise along the bottom (I think my mirror is the cause and has to go now!) as otherwise it would be almost passable.
  11. Morning all, I managed to get my guiding sorted on my rig last night and had zero throwaway subs on five minute exposures. Hopefully the graph watching addiction that is associated with this will subside? Having achieved this personal milestone I think I should celebrate by moving on to my next project. My rig is currently a HEQ5, 130P-DS, Canon DSLR and a finder guider. I’m thinking to make the most of my limited imaging time it would be useful to run two imaging rigs at the same time. I have a second Canon DSLR already so was contemplating grabbing another 130P-DS and dual mounting them on my HEQ5. Has anyone done this before that could offer advice? Is this a crazy idea that wouldn’t work? Would it be too much for the HEQ5 to handle/image with? Any advice is appreciated as its not something I have done before!
  12. Woke up for a 2AM moon mosaic. It was cloudy with a few drops of rain when I first looked out, but I gave it 30 minutes as all the weather apps were showing a clear break and low and behold, the clouds parted for an hour for me to do my stuff. First mosaic with the 130P-DS and it was lots quicker than doing it with my 200p due to the decrease in magnification. Taken with a 130P-DS, HEQ5, QHY5l-iiC. Approx 11 panes in this image of varying qualities.
