Martin,
thank you, clarifies that matter for me.
This is going to be a trial run for a 20-22″ F:5.5 Newtonian, Surrier Truss mounted on a Paramount ME for CCD deep sky imaging.
Cheers Eric

The link given took me to the publication which had had been written in either the German or English language. I take it then that there is not a fully English version. Unfortunately, I can get by in Italian,but not German.
The more pro-am type publications the better and I wish you success.

James,
If your going to the BAA Comets section meeting next month in Northampton I give them to you as Iwill also be attending .
Eric
James,
I can help you out there. During my time at Hertfordshire University they skipped the whole southern sky survey plates as taking up too much room and it was all digitized anyway. I managed to retrieve some from the skip and could let you have one or two.

I can’t get it to work with windows 10, though I have tried the various fixes propo
Hopefully any new versions will not need fixes. I expect it’s me and my limited computer skills.

Whilst on an OU summer school at Stirling Uni one summer during the 80’s I did notice it whilst walking past on a day out.
Nice to know that all these years later I was correct in what I thought it was. 🙂

Hi Nik,
I have a 2.7m Pulsar dome, that sits on top of a wooden building.
I found I got heavy dew on the dome and more worryingly, surface water on the metal work of the paramount gem. I also keep a desktop in a large plastic box. I keep the PC powered on and have installed a small DE-humidifier that runs 24/7 during the damp season.
I have had no problems during the past four years.

Hi Bill,
I’ve been following this thread with a great deal of interest. i is something I’d very much like to get involved with and I’ve been looking at setting up my own station using a Watec 910 HX /RC mono camera (that I could also use for asteroid/star occultation events as and when)
I’d like a little more guidance on camera lenses and diffraction gratings and how to source them and mount them in relation to the camera lens. Maybe you could drop me an email.

It would be nice to have regular publication that either lifted the level of “expertise/difficulty” or included more sophisticated articles. The level of a great deal of much amateur work is on a par with some of the lesser funded, smaller university projects.
I have subscribed to a number of monthly popular astronomy magazines and find that I skim read through them once and rarely return for further reading. I’ve stopped taking Sky and Telescope recently and should have done so some years ago.
Thanks for all comments and suggestions . I think I will settle for Calum’s suggestion of using Baader Optical Wonder Cleaning Fluid and see how I get on with that having first removed loose dust etc with canned air.
Regards Eric
Thank you for your replies.
Martin. Yes I have seen those short films which have been helpful I will use the much of the technique described but I’m too afraid to try Ron’s method.
Neil. I’m not removing the corrector plate, just doing the outside and tilting the tube slightly.
Callum. I have heard the Baader cleaning fluid mentioned to me in the recent past. I may take a look at that.
Richard, thanks .Yes it’s de-ionised water I have and I will filter it and mix as a solution with isoropyl alcohol .
Re the washing up liquid this is usually quoted and advice is not to use the waxy ones. Would fairy liquid do?
I’ll use pure kleenex tissues and get the cotton wool from a pharmacist
Thanks to all for your comments.
About painting the moon black. It virtually has been. it reflects about as much light as a lump of coal of the same size and same distence1
