    Not 100% sure but I think he means one of these ... https://www.firstlightoptics.com/visual-oberving-rgb-filter-sets/astro-essentials-125-wratten-47-violet-filter.html

    Are you sure it's RA ?
  3. knobby
    🙂 Still a lovely image !

    I love a good old handheld DSLR moon shot... Takes me back to where the imaging journey began 👍🏻

    Heq5 - old, reliable, solid, easily fixed and tinkered with. GEM28 - modern, light weight, varying build quality, but nice if you get a good one.

    Is this with the counterweight connected, sometimes the bar can be a bit loose and clunks as it changes direction ?

    Very interesting Geoff! I've just nabbed a 1.5 Barlow to try (if I ever get out again) on my zwo224 /C9.25 ... I usually use a 2x but as the seeing is always naff where I live, thought I'd give it a go.

    Wow 👍🏻 And from a smartphone... Really nice !

    Interesting stuff ! Don't forget that with a polemaster it has to be calibrated on first use and again if it's ever knocked or moved. Possibly why differing results to sharpcap. I'm using an ipolar now and it's usually very close to sharpcap result.

    General wisdom says darks should match temperature of lights so with an uncooled camera might not be that effective. But give it a go and process with and without to see what you think maybe.

    Is everything screw fit ? don't know the redcat, but could the tilt be anywhere else ?
  12. knobby
    Looks like tilt ... Use ASTAP as it's free, shows an approximation of tilt. This is your Ha from the google drive.

    Excellent !

    Also try slightly warming the larger part.

    I can't be the only one that thought this was a thread about zwo mini cameras 😂

    My quick handheld capture with Nikon DSLR - 300 mm lens - Baader solar film.
  17. knobby
    Amazing !

    Hi chaps, did a quick lunch break grab with the Nikon D5600 - 300mm lens - DIY solar filter. 40 Raw files, stacked and best 50% sharpened in registax then colourised in CS6.

    Very nice ! Plenty of detail yet nice and smooth.
  20. knobby
    Both 😂 Plus it's always cloudy !

    Very nice Peter. How long was the capture ?
  22. knobby
    It does slew very slowly during final alignment ... Are you sure it's not moving ?

    Hi @Gottzi Just noticed you joined the group. It's pretty quiet here but a few of us do post occasionally.

    Saw the same thing last night, very hard to focus... Then it would drift in and out to a blur , yet the planet seemed fairly stable.

    Lovely image ! Io being misshapen is most likely stacking induced.
