  1. Thanks for the reply. This one slipped through the net when I was doing my googling. Reviews look good, so I'll add this to the mix. Weight isn't too much of a problem, it's more the quality of view across the field which I care most about.
  2. Ideally you would want some kind of tracking, particularly at high magnification with a small sensor chip which you have in most webcams. With a DSLR, the chip is larger so effectively gives you a wider field of view, so the object you are imaging will stay in view for longer. Most stacking software will allow you to crop and align the frames before you stack them, so a bit of drift over the duration of the video clip is not too big a deal, providing you keep the clips short and re-centre the object between clips. I invested in a set of dual axis drive motors for my EQ5 mount and the are drive systems out there for dobs, so that may be something to consider.
  3. I have a Nikon D3100 and have used it with some success on my SW Evostar 120 with a 5x Powermate to image Jupiter and Saturn. I used Live View to focus and stacked the frames from a 1 minute video clip using Linkeos (I have a Mac!). It's certainly possible with a little patience. The attached image was my first attempt and is a little out of focus, but not too bad considering the humble kit I was using. My advice is give it a go - you might be surprised and you'll learn some techniques which will stand you in good stead. Cheers, Steve
  4. Hi, I have recently bought a William Optics ZenithStar 71 refractor as a grab and go scope and also for some wide field observing and imaging. I absolutely love the scope, but am keen to add a 2" eyepiece of around 30-35mm so I can enjoy the wider views this would give me. I'm on a reasonably tight budget and have been looking at the SW Panaview and Aero eyepieces as they seem to get good reviews. Before I make my choice, I have a few questions which I hope someone may be able to answer - 1. At f5.9, will the the Aero show significant reduction in distortion towards the edge of the field of view - enough to make it worth the extra cost? 2. Are there any other eyepieces out there around this price point which would be worth considering? Thanks Steve
  5. Thanks all for the warm welcome and advice. Looking forward to getting out there again! Steve
  6. Hi i'm new to astronomy, but have had an urge to own a telescope since was a kid. Well, 30-odd years later and I now have a Sky Watcher Evostar 120 with an EQ5 mount - thanks to Santa aka my wife! Last night I took it out to my front garden and once the clouds had cleared I managed to get my first ever view of Jupiter and the four Gallilean moons - amazing! I also took a look at the Orion Nebula and the Pleiades and Hyades clusters. It's going to take me some time to get the hang of setting up and navigating and I can see I'm going to need to invest in a Barlow lens (or two), plus a motor drive for my mount down the line, but I had a great time last night. I'm hooked! Looking around the site, there is a wealth of knowledge and experience which I'll definitely be making use of. cheers, Steve
