Hi there, our Astro group were booked into our normal dark skies venue for an observing weekend in February. Unfortunately, the accommodations are now going to be undergoing renovation and will be closed for the first 3 months of the year. We are looking at a couple of alternative venues. These are field study centres, one at Blancathra near Keswick and the other Malham Tarn in the Yorkshire Dales national park. Wondering if anybody has any observing experience of the skies in these areas.
Hi. Was up at dawn observing Mercury rising in the southeast and slowly swept my binoculars left. I was able to vaguely see a small triangle formed by Upsilon Ophiuchi, HR 6128 and HR 6137. That was the limit of view as sunlight was washing out anything else to the left of that. But I clicked on the adjacent HR6144 star in my Sky Guide app and it lists as being 6,900 light years away. When I checked the Ski Safari app, the same star is listed as 1,900 light years. I went online and found little info but, “In the Sky” web page it’s HR 6144 at 9 kilo years / 9,000 light years. Does anyone have any info as to why the huge discrepancies?
Thanks in advance for your help.
POLAR ALIGNMENT IF THE POLE STAR IS OBSTRUCTED (e.g. OBSERVING ON A S-FACING BALCONY!!!) Set up your scope on the floor (assuming it's reasonably level) in equatorial mode, with a rough guess at North. Put the tube into whatever 'home' position the instructions specify, or that you have chosen. Now choose an easily recognisable bright star at mid altitude. Pretend you HAVE polar aligned, and tell the scope to go to this star. When the slewing stops lift the scope very gently and turn the mount round till the star is in the centre of the field of view and you should have a fairly good polar alignment. If you are for example videoing planets and can also autoguide, this alignment may be all you need. But you can now refine it by the drift method if you need to - see https://www.skyandtelescope.com/astronomy-resources/accurate-polar-alignment/ This method should be quite useful for Southern hemisphere observing, where the 'south pole star' - Sigma Octantis - is difficult to find especially in light polluted skies. And of course my advice here applies if you have a North-facing balcony!
HEY its about time eh!!!! my first astrophoto with a dedicated cam using all the bells and whistles like iCap and Registax.
Programs that are still alien mumbo jumbo to me, but after eating a whole bunch of youtube videos and a bunch more trial and error, I finally pumped out this abomination, or so it must seem to you Pro's lol
I had a very vague idea of how to set up proper parameters in iCap for lunar imaging but I tried several settings and used youtube also, regarding wavelets, I basically dragged sliders all over the place
and watched changes occur. There is much to learn about post work in iCap, but i'll give it the old college try lol, my sole reason for posting is for feedback, this is where you Pro's shine, oh do I need
Anyway, it is my first astrophoto so no matter how much better it can be, well, it will do for now and I say that with a bit of swag because hey! at least I see craters there lol.
Exposure time.....no clue!
Number of frames....a whole bunch
Attempts.....way too many!
Wavelet values.....all over the place
De noising....didn't work at all I think
Resolution...12 something by ??? forgot
The conditions were horrid, a mak is not an imaging scope as I have learned the hard way, F1800 not good, I will definitely be looking at a much shorter FL scope,
Far too tight an image, I would need a 50 shot mosaic for full moon, or a focal reducer which I'm not sure anyone makes for my Mak.
