RE: Lock down and clear skies

January 7th 2021

Hi Ian, Thanks It’s a bit frustrating to see the Horse Head in my 66 mm refractor after 5 seconds exposure, but not able to see it through my 500 mm reflector, but I do like the challenge of spotting faint fuzzies.  The addition of the DSC will speed things up finding stuff and is considered cheating a bit.  So EAA is different to visual.  This is the Lodestar image on the 66 mm Equinox, 10 seconds x 30.  Interestingly, the Lodestar on the 66 mm refractor has ~ the ...Continue Reading

Re: Lock down and clear skies

January 7th 2021

Hello Trevor, Nice write up. I also had some clear skies last night for the first time since before Christmas. I had been using the new camera on M 76, but the skies weren’t as clear as the satellite image suggested. The very early evening was OK, but then it clouded over for a few hours, even though the satellite image suggested clear skies. It eventually cleared again, but by then, M 76 was below the northern roof line of the observatory so I started on NGC 1514. I think that sometimes, low cold clouds can confuse ...Continue Reading

Lock down and clear skies

January 7th 2021

On Wednesday I was sitting in my office yesterday afternoon in a Teams meeting when I suddenly noticed that the sunlight was going into the Web cam and blowing out the image.   Its been a long time, but the end result was lockdown-clear-skies had returned.  I had been waiting since the 24th December to try out the new Nexus DCS on the  Dobsonian  having done a preliminary test on that evening to show all was working.  So planning was done in DSP 8 ( updated from an ...Continue Reading

Re: Plato crater views.

December 27th 2020

Hi SteveI recall Pete Lawrence organised a whole team of imagers to do just what you are talking about.  It was using web cams and C11s. Each observer took an area and somebody cobbled it all together to make a huge single image of the Moon. Sounds like hard work and will keep you going until the skies clear.👍Of course the RC8 and a DSLR just about take the Moon in the whole frame so you could take the movie with that system. A 4k movie would have more than enough detail so it would h ...Continue Reading

December 27th 2020

Hi Trevor, Merry Christmas! Nice write up of your lunar observations.I too was out on the 24th (in the relative comfort of the observatory) with my own moon project. I decided to image some areas of the moon with the 8RC and asi120mc, this then turned into imaging the whole of the moon.Obviously with this combination of camera and scope the field of view is very small, so I ended up making 24 x 2minute videos, overlapping to hopefully make merging easier. It has turned out to be a bigger t ...Continue Reading

TrevorWonderful stuff!(/Given that northern wind-chill I was pleased to abort my attempts at (anything) and return to the warm!/)Thanks for the very detailed descriptions. Quite inspiring.

Plato crater views.

December 26th 2020

The evening of 24th December I was on the hunt for Santa crossing the Tier 4 skies with the big Dobsonian and happened on the rather bright Moon.  Actually it was planned as it was an opportune time to actually see anything other than the underside of cloud and with a crisp clear northerly flow to help with transparency with RH below 80% for the first time in a while.  I was keen to see how many craterlets were visible on the floor of the crater and to see what I could make of the str ...Continue Reading

You can contact us with a ‘subject access request’ if you would like us to provide you with any other information we hold about you.

There is not usually a fee for this, though we can charge a reasonable fee based on the administrative cost of providing the information if a request is manifestly unfounded or excessive, or for requests for further copies of the same information.

Can you ask AAS to remove, limit or correct the data held about you? You could maintain your club membership with your correct name but with limited contact details. AAS needs to have at least one method of contacting you. You could for example simply maintain an up-to-date email address.
