And these for plastic sheets https://www.plasticsheets.com/review/product/list/id/2311/order/561769/#review-form

Here you go Adam, https://www.sblite.co.uk/neutral-density/265-409-rosco-299-12-neutral-density.html#/23-sheet_roll-sheet https://www.sblite.co.uk/neutral-density/264-407-rosco-211-9-neutral-density.html#/23-sheet_roll-sheet https://www.sblite.co.uk/neutral-density/263-405-lee-filters-210-6-neutral-density.html#/23-sheet_roll-sheet I use a combination to get the right ADU HTH

Hi, I guessed you might think that, but seriously it will not create an even pattern. A while ago I bought some drawing flat panels which had a honeycomb effect and there was no way to hide them with a white t-shirt. I eventually settled on these smaller flat panels and these larger flat panels they can be powered from a 12v feed off my Pegasus UPB and although the dimmer is fairly useless, I use white plastic sheets combined with theatre light gels to get the right ADU. HTH

My worry would be that it claims to be a honeycomb design, if so then the image maybe broken up and not a totally flat unbroken white.

Many years ago I used to own a small company making waterproof gear for the angling market, it didn't take us long to realise that the only true waterproof seam was a taped one, we regularly had companies contact us and say that they had a special thread that when it got wet would swell and seal the holes, similar to what 365 claim, at the time I was sceptical and no competitors went down that road either. Without taped seams you will see the puncture marks of the needle and my 365 cover leaked like a sieve, I have 3 Telegizmo 365 covers and none of them will I use without a proper taped cover that is breathable over the top. Needles get exceptionally hot when going through thick material, I had one got straight the tip of my finger and it was that hot it sealed the entry and exit wounds, it could be that Telegizmo are thinking along those lines, but I would be very dubious if they are as plastic can and does melt with the heat of the needles. The material Telegizmo use if really superb and after all this time there is no sign of any wear. Since that experience a couple of years ago, my mounts, camera's etc. have been outside and are as dry as a bone every time I take the covers, I just like to take extra precautions.

Just to add, the Baader are excellent but there are batches out there that create halos, if you do go down that route and get halos then reject them and send them back.

Chroma originally made the filters for Astrodon, they are every bit an equal to Astrodon. If in doubt ask @swag72 I bought mine direct from Chroma, and I use 2” unmounted. Off the top of my head the LRGB were about £800 and although I got a special deal on the NB you are probably looking at around £2k for them. I am having zero halos and some lovely images even with a full moon. Did you mean sodium as I think you might have meant Sulphur SII. I looked at Nitrogen but to be truthful can’t really see the point for now and as Dave said, probably more useful for planetary.

John at Jtech Design (he does a lot for FLO) is currently making me a couple of adapters john@jtechdesign.co.uk sorry not got a phone number

Lovely image Gina, how are you managing such tight stars with no guiding? That lens is a cracker.

Yes I did and FLO replaced it, my mount filled up with water, fortunately it dried out fine

Telegizmo 365 and ENS Breathable cover http://ensoptical.co.uk/telescope-covers/tempest-med-cover My first 365 leaked like a sieve, so I always use two covers and never had a problem since.

Hi Brian, I leave my Mount, scope, camera, filters, in fact everything outside under a 365 and an ENS cover and have done with all my equipment since getting a permanganate pier, I'm up and running in 5 mins. I tend to regularly check the PA as taking the covers on and off gives me a small concern with accuracy, but that's it, I leave plenty of room underneath so that everything can breath: -

Just wondered who was going to the Practical Astronomy Show (PAS) 2020 on the 21st March https://practicalastroshow.com/ Last year was a cracking show with some fabulous discounts and offers and entry is free as are the talks as well. More details here as well: - https://www.facebook.com/events/377164579790380/ Looking forward to see many of you there!

I used to make up up my own power distribution boxes with USB etc. It worked and very reliably but I wanted things tidier so I switched to the Pegasus Ultimate power box, brilliant piece of hardware that I now use with all my OTA's

Thanks Mark and we are only 6 miles apart

Mine includes the complete Adobe suite, especially Acrobat Pro which I use 20 times a day

I had the same thing, I bought what I thought was a genuine copy for £1600, turns out the company were con artists and I now have to pay £48.99 a month for the full version, I was not happy and reported to Action Fraud and they said there was nothing they could do about it.

With storms and unpredictable weather, not to mention a nearly full moon, I chose to go for M1 as I hadn't imaged this before. I'm recovering from major spinal surgery, so I wanted to keep my mind off the pain. I feel that it has come out OK, I wanted some LRGB for the star colours but the clouds arrived and held me back. I particularly like the tale about M1: - The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant in the constellation of Taurus. The current name is due to William Parsons, 3rd Earl of Rosse, who observed the object in 1840 using a 36-inch telescope and produced a drawing that looked somewhat like a crab. Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a historical supernova explosion. At an apparent magnitude of 8.4, comparable to that of Saturn's moon Titan, it is not visible to the naked eye but can be made out using binoculars under favourable conditions. The nebula lies in the Perseus Arm of the Milky Way galaxy, at a distance of about 2.0 kiloparsecs (6,500 ly) from Earth. It has a diameter of 3.4 parsecs (11 ly), corresponding to an apparent diameter of some 7 arcminutes, and is expanding at a rate of about 1,500 kilometres per second (930 mi/s), or 0.5% of the speed of light. At the center of the nebula lies the Crab Pulsar, a neutron star 28–30 kilometres (17–19 mi) across with a spin rate of 30.2 times per second, which emits pulses of radiation from gamma rays to radio waves. At X-ray and gamma ray energies above 30 keV, the Crab Nebula is generally the brightest persistent source in the sky, with measured flux extending to above 10 TeV. The nebula's radiation allows detailed study of celestial bodies that occult it. In the 1950s and 1960s, the Sun's corona was mapped from observations of the Crab Nebula's radio waves passing through it, and in 2003, the thickness of the atmosphere of Saturn's moon Titan was measured as it blocked out X-rays from the nebula. Link to my Astrobin Library https://www.astrobin.com/s944bm/ This was taken over the 12th, 15th and 16th January 2020. 9 x 1200s Ha 8 x 1200s OIII 6 x 1200s SII 10"GSO Truss, iOptron 120EC, Moravian G2-8300 MkII, Chroma unmounted 2" filters 3nm I have spent no more than 15 mins post processing, indeed it could benefit from more, but I rather like to see my images without all the tatting about as I feel they are more natural.

I choose my targets carefully Dave, if it is a full moon then NB all the way, otherwise I shoot in the opposite part of the sky to the moon, works for me.

Well it's now 2 weeks since my op and I was desperate to take my mind off the pain, so I managed just 7 x 1200s of Ha on M1, I lost a load of subs due to clouds, but it was just a pleasure to get out and do some imaging, hopefully get my OIII and SII over the next couple of weeks: - NB. Yep just because there is a full moon doesn't stop me, I just choose my subject differently.

Seriously Olly, it was a piece of cake, add the correct version to the bin directory and then just add the module and jobs a good'un if you PM me you number I can give you a call and talk you through it.

I tend to shoot Ha and SII when a full moon and the OIII when the moon is out of the way. Good Choma Filters really help.

There was a known issue with the Baader NB filters creating Halos, originally the owner refused to accept that there was an issue, until it was pointed out very clearly to him by my mate. Suffice to say the filters were exchange without any quibble and the problem was resolved. Thus the reason why I went down the Chroma route.

I've had doublets and triplets, I was lucky in that I bought both my Esprits second hand in as new condition. The most obvious difference to me was contrast, there was so much more IMHO, especially in Ha. Not sure if that helps?

That was exactly what was going through my mind Olly, I know it means an extra mount and pier, but surely would be far more accurate and less problematic?
