The only view I've had so far that I have 100% confidence in is one with my 10 inch. In that view it was tiny blue dot that was persistent. I'm sure as time goes by my small refractors will show it.

Yes, that's how Sirius B appeared in my 10" Dob. I've never tried for it with a smaller aperture.

Last night we were awarded with clear and steady skies. Seeing was 8 using the Pickering scale. I was able to observe Sirius A and B easily after sunset, in early twilight before full darkness. I used my TV85 refractor with a Nagler 3-5mm zoom ep. The split's best view had a sweet spot power range of 120-150x. The pup was steady, clear, and visible for 30-40 minutes. Full darkness increased the glare of A and made the view no longer possible.

Excellent report. I've been attempting a view with my small refractors but not yet sucessful. I too live in the Tampa area and computer problems I was working on prevented me from giving it a try last night. Thanks for the report its got me motivated to keep going for it.

I'm glad that you are encouraged Bill! Hope that you have success soon.

Finally got the pup with a small refractor. Just after sunset with a not so dark sky in the Tampa Fl area. Seeing not so great with thin high alt cirrus clouds, estimate Pickering of 6-7. Four inch f/5 refractor using 9mm plus 2.4 Dakin barlow = 133X. Moments of very steady view. Pa of 80. Small dot outside the "sphere" of the primary. I knew it was a matter of time. I think my 80mm scopes would view it but thinking my 60mm's are not yet up to the task.

Congratulations! If the high cirrus clouds are very thin, they can filter some of the glare and improve the visibility of the pup.

Yes I think the thin cirrus clouds aided the view, that is until thicker ones moved in and blocked the view entirly. I was only able to view for about 15 minutes. Bill

Yep. That has been my experience too. I can do it most of the time with an 80mm at ~70x and above, but no dice with a 60mm at any magnification. Maybe when it hits maximum separation in a few years it will be doable in a 60mm.

Regards,

Jim
