First image of sunspot with PST and DMK21

[Daniel_Reardon]

Hi all,

This is the first image I have been able to process with my new DMK21. I used my PST and a 2x Celestron barlow. The focus was slightly off because I couldn't see my laptop screen clearly (I'll have to use an umbrella next time). What do you think about the colourisation? Any further tips would be appreciated also.

Cheers,

- Daniel

Sweet. Thanks for sharing. I have a pst and have been wanting to get a good ccd, like the one your using. It's nice to see the detail a good ccd can pick up compared to some generic webcams, which is what I'm using.

Post some more when you get your focus figured out. But still great image!

Along with the DMK, I'm also looking forward to getting a powermate to substitute the barlow. Awesomeness would only follow

Put a blanket over your head and laptop for focusing. I did that for my last pics and it was a day-night difference (and I still have a standard rack&pinion on my SW 150PL). Umbrella just doesn't do it

I was able to find a shady spot to hide with my laptop while my telescope was in the sun today. Took 13Gb of video (though focus was still very difficult because the atmosphere was very turbulent. Nevertheless I should be able to get some nice images processed and organised into a mosaic of the whole disk. We will see and I'll post back with results.

Making a sunshield from a cardboard box is helpful too and not as hot as a black sheet. A sunhat is helpful as well to keep the eyes better adjusted to brightness variations.
