Re: Algol Eclipse 23/24 January

Hello Sonia This type of graph is a just a convenient way of plotting the the changing brightness of a variable star - any variable star - over a period of time. The graph therefore shows a timed series of data points known as the light curve. Beta Persei is the variable star here and that star is a...

Re: Algol Eclipse 23/24 January

Hi Jeff, Sometimes it's possible to identify estimates that are unquestionably wrong because you discover the cause - so these can be annotated as such and, yes, I send my estimates to Matthew (vss Director). I've observed variables for forty-odd years now, but I'm not a variable star fanatic. My ob...

Re: Algol Eclipse 23/24 January

Hello Jeff and SkyB, Thanks and I appreciate your comments. Visual estimates in a sequence are never without errors on the part of the observer and compounded by varying sky conditions over a long observing session. I think possibly the estimates at 4hr.25 and 5hr.25 are "rogue ones", but ...

Algol Eclipse 23/24 January

Hello, just thought I’d share my observations of Algol’s eclipse through last night, 23/24 Jan. Although the first two points on the graph are unaided eye estimates, the rest were made using my recently acquired 6x30 monocular with its useful huge field of view. The monocular saved the night really....

Re: New to SPA *helloooooooo*

Welcome SunsetTwilight. Thought I'd just mention to watch Vicky's SPA video show on youtube on Fridays at 8pm if you don't know of it. Kind thoughts, Bob. Got to go, Algol's in eclipse!

Re: The Sun - 21st January

Nice view of this odd little group Cliff. I finally got the telescope out into the drive this morning at 1030 UT and saw the spot group by projection with a 60mm aperture at f15 and, another little group had emerged in the Sun's northern hemisphere comprising a pair of small spots and an exceedingly...

Re: The Moon through binoculars

Thanks Mike, on the basis of your comments it seems worth looking into. I’ve ordered one of these 6x30s today from an interesting bird watching set up in Norfolk called Clayspy, £22.98 with postage. Yes, I’m a bit skeptical of the claimed 10.5 degree fov, but anything approaching that will be intere...

Re: The Moon through binoculars

Anyone bought or tried the Celestron 6x30 outlander monocular, 10.5 degree claimed fov, 20mm eye relief, approx £20 ? Bob

Re: Arecibo Telescope to close.

That sounds like a great idea John. I’d kick in £50; if you can cannibalise a decent microwave oven and adapt it with your engineering skills we could upgrade the Lovell. Actually it does sounds like a good idea. I wonder what it would cost, but importantly would the old girl stand the extra weight?...

Re: Sol today

The only heat problems that I have had with apertures between 80 and 100mm have been the plastics comprising field stops melting in eyepiece barrels. It hasn't happened yet with the 60mm aperture and my 15mm plossl (which has quite a wide field stop). Bob

Stella, what did you use to spot this with? Is it a US spy satellite? Happy New Year. Bob
