Testing The ZWO 183mm on the Sun - 8th May
I recently bought a ZWO 183mm camera, primarily as it will allow huge full disks (WL, CaK, Ha, Lunar) with my APM 100/800 scope. Well after many years of having a broken continuum filter, I finally got round to testing it this weekend. Saturday was sunny but I had the job of getting the boat on it's 7 hour journey back to its mooring following several weeks of maintenance on it out of the water. Sunday dawned with rain, but by later afternoon the clouds had broken and I was presented with milky skies. Keen to try out my new acquisitions I used the Lunt wedge for a bit of white light action...
First off the full disk, a huge image, so double click to view in flickr, then double click to view full size. The granulation is nicely visible!

Next, swapping cameras for the ZWO 290mm, and using the APM 1.6x telecentric to get a slightly closer perspective on the regions of interest...

I don't think these have come out too bad considering i've not done any whitelight in years. I think next time I will try a bit more 'zoom' if the seeing allows!
Hope you like these.

Very clear and sharp WL images Mark.
Nice details in and around the spots.

Re: Testing The ZWO 183mm on the Sun - 8th May
Beautiful images, Mark!
The 183MM is a perfect match for FD's with the 800mm fl. Here's my Continuum from the same date with the same camera, but with the 80/800.
Best regards,
Arne

Sharp and very detailed images Mark! Maybe I get a camera but after 10 years

Cracking shots, Mark.
Lots of nice detail in that full disk indeed. The file sizes of these larger resolution cameras are always lots of "fun" to deal with in processing (aka sit around waiting), but definitely worth it

Very nice, Mark. The larger format of the 183 certainly saves making mosaics.

Re: Testing The ZWO 183mm on the Sun - 8th May
Thanks everyone for your kind words. I think I got up to around 25fps with ROI so wasn't recording empty sky.
I also tried on CaK, but by then there were cumulus clouds readily bubbling up, and this reflected in the seeing. This time dropping back to 60mm aperture (50mm would have been better), but otherwise the same setup.

Hopefully will get to image in the evenings later in the week weather allowing.

Re: Testing The ZWO 183mm on the Sun - 8th May
Mark,
Very nice result! I've got 183mm pro and on my first attempt I got grid patterns with the Ha filter - thats got to be the microlens. ZWO FAQ also confirms such behaviour. This gives me a problem of getting a flat frame with full disk.
Did you try Ha? After seeing these results, I'm thinking to give it a try once more.

Re: Testing The ZWO 183mm on the Sun - 8th May
Excellent results Mark! Ordered one as well about an hour ago - to be paired with a 80mm f6 scope and a 1.75x telecentric for full disks, as I am getting tired of mosaics with the 290!

Very nice Mark, that looks like a good cam for the purpose.
Granulation easily and nice visible.

Re: Testing The ZWO 183mm on the Sun - 8th May
Thanks everyone! I did try in Ha, on 2 different scopes and don't get any fixed pattern noise which i'm pleased about. I didn't record any data as my hardrive was full though...
Spent some time with my IT man at work today getting a flavour for what is out there in terms of me buying a new laptop for imaging - what I thought I wanted to spend and what I wanted to get are miles apart, so need to do some more reading and digging into this before making rash decisions. Until then I cant take as many images in one session as I would like

Re: Testing The ZWO 183mm on the Sun - 8th May
Mark,
You got the individual granules! Nice. So far my best white light images come up just short of showing them looking more as Terry would say " Porridge ". I think my inability to track hampers me here since if the alignment of the images is off just a tiny bit it reduces detail. Seeing is another factor as well.
Anyway, very nice job. You should do white light more often!
James
P.S. Nice CaK too but we all know you can do that well!

Re: Testing The ZWO 183mm on the Sun - 8th May
I have a Sky-Watcher AZGTI but it won't hold the C102 or SMII90. I should have gotten the SolarQuest Vs the AZGTI. It tracks the sun better. I do often use the AZGTI with my Astro-Tech AT72EDII and have used it with the SMII60. It's the non-driven Losmandy AZ8 that I use with the bigger scopes. It's great for visual but a challenge for imaging.
