Hi I am happy to have finally signed up to SL and am just trying to take in the wealth of information here.Could anyone advise me at this early stage? I have been taking night shots of Milky way and Aurora using a Sony A7s for the last year or so.I got this camera with an eye to getting a Heq5 mount and have now added a Sykwatcher Ed80 to the set up.I have imaged the moon and hoped to move on to some easy DSO but my first few attempts i have noticed the well documented Star eater problem on my images which occurs in bulb mode.After finally getting even to this stage its disappointing to see the donut stars that are being truncated by the camera.I could maybe sell it to get an astro modded Canon which might give better results or would it be better to look out for a Ccd and filter wheel.I dont want to get too muddled at this early stage as i'm not sure how complicated it will be to set up ccd but also really want to have a set up that works for a good while without wasting any more money after the problem with the A7. If anyone has a work around for the star eater thsat would also be good as i could maybe get that modded but not as it is currently working.I live in a green zone for LP but on the edge of a dark sky area.Could anyone give me some pointers as i would like to get in to some more AP but feel i'm lacking direction on how to move forward. Many thanks Craig
My new Skywatcher ED 80 arrived yesterday and I can only say how impressed and blown away I am after one session. First impressions: The version I bought came fully packed in the aluminium carry case, everything neatly bagged and protected. As I unwrapped the OTA and accessories I was impressed how well made everything was, no plastic bits and solid castings for the finder scope. Tube rings and dovetail suitably solid. I had never used 2" EP before and therefore I could not believe the size and weight of the diagonal and the 28mm lens supplied, chunky to say the least, do not drop this on your toes. The 2" EP holder also includes a 1.25" adapter. Again well made with rings tightened by screws rather than just two screws biting into the nosepiece. Also in the kit were the T ring adapters so you can mount and DSLR at prime focus. 1st Light: I bought the SWED80 for astrophotography and widefield use. I have my 6SE for lunar and planetary work. The assembled OTA weighs in at 4Kg with everything attached (except the DSLR). The idea is that I use my iOptron Smart EQ mount for the ED80, this is rated for a payload of 5Kg. I needed to add extra mass to the counterweight as the 950g mass supplied is not enough. I am checking with iOptron just how much mass the mount can take. My extra mass was made up of 4 oz fishing weights strung together with cable ties. I spent some time getting the 9x50 viewfinder aligned, I would have preferred a viewfinder with a 90Ddeg viewer as I am not so limber anymore. I also did a quick south pole align. Far from ideal as I am still struggling with getting a clear view of Sig Octans. However it was enough for a quick align and make use of the GOTO on the mount. The optics on the SW ED80 are incredible. Used 1.25" EPs, 32, 15 and 9mm plus the diveres weight like 28mm supplied. I used the Jewel box as a test, the Moon and early this morning Saturn. The Jewel Box was crisp and clean in all EP's and in the wider field even the edges were acceptable, the Moon and Saturn again clear and crisp, some slight aberration on the edges of the moon under high power. Saturn was clearer and cleaner than in my 6SE, maybe I should have set up that too and done a side by side test. The 10:1 focuser is a gem! Fast to just on then fine control to achieve focus. Love it! This will be very very usefull when I start to use a camera and a webcam on it. Downside: None really, except my wife will scragg me and I need to consider a better EQ mount.......the Sirens of monetary black hole in the Dark Side are calling........
Hi. I have got myself an ED80 scope, and have been using the 28mm EP that came with it, but when trying to look at Saturn, it just looks like a bright dot. I would like to see it larger and in more clarity. On doing some hunting around I have read that the Tele Vue Nagler Zoom EP's are regarded as a good quality EP that will last. So the question is, will the 3-6mm EP or the 2-4mm nagler EP's be suitable for my ED80. I got this scope mainly for AP, but I am intersted in visual work as well, so eventually I may get a scope that is a dedicated visual scope, and hopefully the Nagler EP would suit that scope as well. Any advice would be great!
