    Default Friday's picture—DSLR w/2X Barlow



    I wasn't going to even set things up today but my 2X Barlow arrived. It's quite an improvement. The sun is now covering four times the surface area of the imager. Not only am I getting more detail but the illumination is more even. Not perfect but still a big improvement. Now it's decent false coloring that's eluding me.

    WOW!!! That is awesome! I was just out looking at the sun and you've caught so much of the detail. Very nice!!

    What settings did you use? I seem to be able to get the prominences, but not the disk details.

    Very cool shot, Mac!

    One of these days I might actually buy a better quality Barlow?? Possibly try it with my PST. I have a 2x Barlow (had it for years), but, I was never crazy about using it. Maybe I'll try the one I have with the PST, just to see if I notice any difference...

    Anyway, great job!

    I checked the manual for your scope Marsha (I downloaded a few manuals before making my purchase to really check out the various solar scopes) and basically it seem a matter of playing with the Elation thing as it is on my PST. It took me a couple of tries before I see some detail - certainly more with the Meade zoom than the Celestron one. I move it one way to zero in on the prominences and the other to zero in on various other details. I also check out Theo's site was well as this one to see where (if any) the action is and then changing my elation control I can usually see them

    www.SolarMonitor.org

    Good luck!

    I haven't tried my barlow (an Orion Shorty Plus) yet but now I'm tempted, especially since getting my new Meade zoom. But it won't be today because (and no surprise here) because I now want to try the barlow, it's very overcast - what else is new

    BTW,since I have a birthday coming up very soon, I'm tempted to get the Double Stack upgrade now instead of waiting for Christmas. I know, I said the PST would be my birthday present........perhaps I lied to myself

    Abb,

    No, I meant I haven't been able to get good disk detail with my camera, yet. I can see amazing detail with my scope. I just need to figure out the best settings to shoot with. Maybe I need to try the 2x barlow and move the draw tube a bit. Thanks.

    Thanks for all the positive feedback. It makes being out in the 102° sun with a blanket over my head and sweat running in my eyes worthwhile.

    The proms were shot at 0.3". The disk was shot at 1/80". Both at ASA 100. These are longer exposures than before as the Barlow makes the image dimmer. The disk exposure is just below the clipping point. At 1/60" the exposure was clipped. I check the red histogram while I'm shooting to find the exposure time that falls just short of clipping.

    For the proms I start out with them being too bright, bracket my way down until they're too dim and them pick the best exposure out of the lot. I processed the two images separately then combined them for the final picture.

    It was also much easier to focus in live view with the larger image. The huge proms didn't hurt. I was able to completely forgo the laptop for this session.

    That's a relief!!! I was beginning the think you may have a faulty unit! I too see more detail now with the new zoom than I did with my other - like you said "amazing"

    Hindsight being 20/20, perhaps I should have sprung for the cheapest 60mm Solarmax but even when I got my PST, I didn't think I'd take to looking at 1 star vs tons of them like I did, not by a long shot! Fortunately, my PST is upgradeable and Theo gets some super incredible shots with his double stacked PST.

    As for take pics, I may try it one day with my wife's 7.2MP Panasonic camera. For the moment, I wish the clouds would clear so I can try my barlow - maybe if I stop being so anxious they'll clear

    Stay Cool (it's hot as Hades here!)
