    Tomorrows world

    I have a copy of the Tomorrows World book from the late 1970's/early 1980's. #2 TV programme on my list of TV greats... #1 being Sky at Night when I had a TV. Back to the original question, the nearest I can think of it for today's generation is Click, (with Spencer Kelly), on the B.B.C. News channel or B.B.C. iPlayer app. https://www.bbc.co.uk/programmes/p06k5f4l
  2. I was watching a YouTube video last week about 'white-light' solar viewing and the narrator says go for a simple eyepiece, (i.e. not to many lens elements), such as a Huygens, as it only comprises of two-elements, rather than something with more elements. So my question is... what type do you use?

    Tiffs or jpegs when saving images

    Overview — JPG & TIFF 1. JPG images are 'lossy' in nature while TIFFs are 'lossless' 2. JPGs are much smaller compared to TIFFs even when compressed 3. TIFF is desired when the image still needs to undergo processing while JPG is best for final images 4. TIFF provides a compromise between RAW and JPGs 5. TIFF users are mostly professionals while common people use JPG 6. TIFFs are very rare in the internet while JPG is the norm for photos 7. JPG (.jpg) and JPEG (.jpeg) are two file extensions used in the JPEG file format And now for some more cofusion... Overview — RAW & TIFF RAW: The RAW format is referred to as the digital negative. The RAW format simply preserves the image information as collected by the camera sensor. It is the minimally processed data as captured by the camera sensor and holds information of every pixel of the sensor. TIFF: TIFF is a file format and is an acronym for “Tagged Image File Format”. It is one of the popular formats for high color depth images. The TIFF files usually have either the TIFF or TIF filename extension. File Size RAW: RAW has a data depth of 12 bit or more. The file size is big and eats up lots of space on your memory card. TIFF: The TIFF normally saves 8 bits or 16 bits per color (red, green, blue) for 24-bit and 48-bit totals, respectively. The file size is even bigger than RAW and the space occupancy is enormous. Thus, buffer is filled up quickly and processing time increases, hindering your capacity to quickly shoot photos one after the other. And to make it even nore confusing or interesting... Nikon use a format called .NEF - I do not know whether Canon or other camera brands use another format.
  6. HI @koopakid If you can save for bit more longer, then I personally would go for one of these --->https://www.firstlightoptics.com/beginner-telescopes/skywatcher-heritage-130p-flextube.html
  7. Another for Mars. It has been having a bad dust storm, so any 'major' surface features have not been visible. It is also affecting Curiosity, (the six-wheel rover), as it relies on solar power and the Sun to recharge its batteries.

    What did the postman bring?

    @Littleguy80 They are nice eyepieces. I purchased the 'other' one from @F15Rules, then someone asked I knew asked me if I was selling it... and I did. I replaced it with a Circle-T 12.5mm Ortho a few months later.

    Last Saturday

    The early Tasco telescopes were very good. I used to own a Tasco 4ETE. 40x magnification 40mm objective no R&P or helecal focus, (just a slide focus tube) no interchangable eyepieces no finderscope or RDF 10 year guarentee/warrantee, (the dew shield got dented when it was about seven years and got a 'free' replacement) This was my first telescope. It was a 15th birthday from my father & step-mother. It gave me the start into this wonderful hobby. It gave views me my first views of the Moon, Jupiter & Saturn. Great for sunspot projection. My grandfather, (on my mothers side), made a tripod with longer legs from some galvanised trunking/tube, (I think this is when the dew shield got dented). I wish I had kept it now, as I reckon I could have upgraded the focus tube to a 0.965"-1.25" eyepiece holder, (it would be a 'killer' with my TeleVue or Circle-T glass).

    Hello from near the New Forest

    Hi @mankind-nil & son, and welcome to SGL. At the present time all the naked eye visible planets are low down, so don't be disheartened with the views you are seeing. Unfortunately they are going to be low for a more years to come too.
  12. Jupiter & Saturn are low down now and you are seeing them through a 'thicker' atmosphere. As others have also said, it maybe a colliimation issue.

    Moon and Mars

    http://www.astroboot.co.uk have a Revalation Astro 5x Barlow @£20.80 + P&P on offer at present. It may work for planetary photos... (a lot cheaper than a TeleVue 5x PowerMate). Revalation Astro Barlows have been known to be above average from some reviews I have read.
