Perigee Moon

I don't normally take images of the full Moon but since the Moon was at perigee on Sunday evening or close to it, I thought I might try an experiment. Using my Tak FSQ106ED and QSI 6120 camera I get an image at full resolution (binning 1x1) which is 4250W x 2838H pixels. The image scale is 1.2"...

Re: progressive astro imaging

The impression that I got from the last time I tried logging in is that the lease time ran out for the domain name and they decided not to renew it.

Re: Mystery object

Yes I continued to watch this object in the scope for up to about 40 minutes I recall. It was drifting very slowly against the background stars at low power. Then it just split into two distinct parts, each of which moved off in opposite directions. It was at that moment I realised I had been watchi...

Mystery object

This is going back a while now, possibly a couple of years or so. One of those very rare occasions when I saw something in the sky that I couldn't immediately identify (other than I knew it definitely wasn't aliens!) I was in my back garden and it must have been the latter part of the summer as the ...

Re: Choice of Telescope

Hi Chris, My first telescope was a 40mm refractor (of sorts) from Boots which had a tabletop tripod and simple push/pull focuser! I don't think it was even designed as an astronomical telescope since the image was the right way up. I ended up balancing it on two two tables, one on top of the other i...

Re: polar scope setting up

Hi, I realise that this question was posted some time ago so chance are you are sorted by now. I am assuming that the reticle in the EQ6 and HEQ5 mounts are broadly the same. Polaris traces out a circle around the NCP with a diameter of about 80' (arc minutes) or around 1.3 degrees. This circle is r...

Synscan v4 polar alignment

After an observatory refurb I have been getting my mount back into working order and that has meant doing the polar alignment all over again. I have the EQ8 without the polar scope so have been using the Synscan v4 routine instead. Only problem I can't get around is that each time I complete the 3 s...

Re: 10x50 binoculars for beginner

Hi Emma, Not sure whether you are still monitoring this discussion but this would be my advice on binoculars; The exit pupil (aperture/magnification) should be at least 5. This applies particularly if you will be using them handheld. The exit pupil of the binoculars should match as closely as possib...

Re: New to Gazing, looking for a little advice please!

Hi Gareth, Firstly a warm welcome to the SPA. I have to say reading through the first half of your post took me straight back to the days of my first telescope. A family friend bought me a little 40mm terrestrial refractor on a shaky table top tripod for my 10th or 11th birthday. I remember balancin...

Re: How to shoot planets with a 150/750 Newton?

I know this discussion is going back a while but I was in the same position a couple of years back. My solution was to purchase a Skywatcher Skymax 180 maksutov through UK Astro Buy & Sell since it had a basic focal length 3x that of the Newt. This means less reliance on the use of barlows. In m...

Re: Canon 5DSr

Further to my post yesterday I have now read a few reviews about the 5Dsr and these confirmed that the low light performance is nowhere near as good as the 5D mk3. The higher pixel count of the 5Dsr means the pixel size is inevitably smaller by as much as 2um. While recommended as a daytime landscap...

Re: Canon 5DSr

A lot depends on what you want from a DSLR of course. Personally I only dabbled with astrophotography using DSLRs and I have to say I was impressed with the low noise performance of my 5D mk2 compared with previous Canon models I have owned using the APS-C sized sensors. To me that showed the benefi...

Re: Query regarding ZWO ASI120MM camera

Thanks for that Brian. That is exactly the problem. I guess the easiest solution is not to use the barlow!

Re: Imaging with Canon DSLR

Just been looking to see if the 30D has liveview and I can only conclude that it doesn't. If it was me I would upgrade the 30D to a more recent model that does have liveview (ads regularly appear on UK Astro Buy and Sell for example) and then use the EOS Utility that allows you to control the camera...
