    Default Eclipse prep



    I'm traveling to see the eclipse next year. I plan to use Baader film with a small refractor for viewing and imaging. A 0.5 angstrom filter is not in the budget, but would a narrow band HA (nebula) filter improve the results?
    Thanks

    The simple answer is no. I wish it was otherwise then we could all save a bundle of money.
    A Baader Solar Continium Filter may bring out the spicules,. Are you intending to just view the eclipse or are you going to do some imaging ?

    The regular Ha nebula filters don't do anything. You need a very specific narrow band Ha filter.

    Now during totality, I really don't know but would guess you don't want any filter at all.

    I'm contemplating not doing any imaging and just enjoying the view.

    A Baader Solar continuum filter will bring out more details. I love using both film and filter.

    I'm a little late responding, but will share what I use for white-light observations...

    I use a 120mm refractor with a Baader film filter from Kendrick in Canada. They are a great company to deal with and will combine a film with an nice aluminum ring that will fit easily on your scope. See the section entitled "Visual Solar Filters for Scopes (Classic Ring Style)" at this link: Solar Filters - Sun Finder, Baader Astro Solar Film and R-60 Aluminum Rings

    Combine that with a Baader Solar Continuum filter for fine, granular details and you have a good combination.

    One word of caution if you're buying solar film...
    There are two versions of the film... One is for visual and the other is strickly for photography purposes. You want the visual version, even if you are going to do some imaging.

    Here are a couple of recent images using the Baader visual film and a Solar Continuum filter...

    No it won't help. The filter is only used to view the partial phases. The filter is usually removed about 15s before totality and replaced 15s after totality.

    If you buy the solar film, you need to make a holder that is both secure so it won't blow off unexpectedly while you are viewing, but at the same time can be easily and quickly removed in a few seconds without putting any force on the scope so that you don't lose framing.
    This web page describes how to make such a filter. Many people have made this design and really like it.
    cheers

    From what I've found on the web, exposure would remain fairly constant until just before totality.
    Here is a rough plan, would this work?
    Nikon D5300 with 300mm f/3.5 and tele converter
    ISO 100, f/32
    Use ND 5.0 filter, and aperture priority until just before totality.
    Remove filter and attempt to get Baileys Beads
    Reverse the process
    Thanks
