<p>[QUOTE=&quot;Clawcoins, post: 3192839, member: 77814&quot;]I&#039;m not to sure about Takahashi but I think their FSQ 130 line is full frame exposure capable, but I don&#039;t think their 120 line is.</p><p><br /></p><p>I use both DX 24mp and FX 24mp.&nbsp; The DX allows more cropability though (approx.) 2 stops longer exposure.&nbsp; Though I haven&#039;t tested high density FF sensors (d800/850).</p><p><br /></p><p>Just like with lenses a larger &quot;aperture&quot; allows more light in.&nbsp; For Telescopes the width of the optical scope tube - the wider of course allows more light to the sensor than a smaller diameter in the same amount of time.</p><p><br /></p><p>I think the above first nebulae was with a single image 5 inch reflector, on a D7000 16mp DX sensor.&nbsp; The 2nd was 12inch multiple stacked images including multiple light colors.&nbsp; I was also testing full spectrum sensors where you block out areas of the spectrum, then stack them all.&nbsp; Stacking allows shorter exposure (less vibrations) to show a stacked more crisp detail image than one super long exposure - you can also control noise better and don&#039;t need a high end tracking system.&nbsp; Also limited spectrum images.&nbsp; But complexity skyrockets.</p><p><br /></p><p>Problem is refractors due to the cost of the lenses (and additional weight) cost more than Reflectors.&nbsp; Though the better more accurate mirrors you get in a reflector and the prices skyrocket.</p><p><br /></p><p>A good Refractor will have more detail than a lower cost Reflector.</p><p>My 600mm lens offers better cropability details of Saturn/Jupiter, then my 1900mm 5inch or 2,000mm 12inch reflector telescope.&nbsp; Although, do deep space and the lens suffers dramatically in my comparison tests unless you find a nice 8 inch refractor for light gathering color for some reason LOL.</p><p><br /></p><p>but it all varies.&nbsp; My tests are limited to what I have and how actually clear the skies are to the telescope, not the eye.&nbsp; My 12&quot; reflector scope has mounted a smaller refractor or a small 3 or 5 inch reflector when I put it on.</p><p><br /></p><p>My main thing with cameras .. as I&#039;ve gotten older is I use DSLR simply because I have them before mirrorless became more available.&nbsp; I nearly switched to SONY mirrorless but the star eater issue came out.</p><p><br /></p><p>But remote shutter either mechanical, electronic or remotely is important as is a flippy type screen (saves my back and time).&nbsp; Many cameras can have the same sensor, with just the electronics and software being the varying factor.&nbsp; But when it&#039;s dark your shutter speeds and stability comes wildly into play.&nbsp; very minor vibrations (just you sneaking away) can show slight shifts in the images with pinpoint stars on them once you pixel peep with images greater than 1/6th of a second - thus stacking may help.</p><p><br /></p><p>too much to type in a single post ...[/QUOTE]</p><p><br /></p>
