Full Disk on DMK 21 Sensor with SM 60

I have tried this before and never hit the right combination to be able to achieve focus , a few days ago I got lucky . What I used was an Antares 1.25" 0.5X Focal reducer
With this I used a 20mm   "C" mount spacer in place of the nose piece that came with the camera . This allowed the camera to sit very close to the eyepiece holder and spaces the F/R in a correct position .


Here is an image shot today using this combination for the first time with my DMK21

Images From Nov 20

I guess you could say I was getting behind but I wanted to leave Bill's fantastic prom shots at the top for a bit before I posted these . My day was a cool +4c with clear sky's to start until some light cloud moved in at the end of the session . It was a good day for imaging so I took some white light to go with the HA . One more thing I discovered was how to effectively use a 0.5 reducer and take a one shot full disk , so my full disk images will no longer have the bottom sliver cut off .

A couple from Nov 14

It has been very windy here in Ontario lately , to be expected as the colder air moves in .

November 14 Disk

As some who come here know I have been working on a new project . This involves mating my SM 60 with a 127mm refractor . This project has gotten off to a shaky start but is starting to come around now , when I get all the bugs out of it I will post all the details of the build .
  This is an early image from this scope also taken yesterday , DMK 21 and no barlow .

Here is a round of images from November 13, 2013.
I will start out with some images of prominences.

AR1890 at the western limb.

AR1899 at the eastern limb.

Images From November 13

I finally had an opportunity to image again after what seemed like a long time . My conditions were not very good and I had a stiff wind adding to the challenge . Bill also has some great images from yesterday so I will try not to duplicate what he has for you .

A Floating or Detached Prom

Bill has some amazing prom and surface shots that I am sure he will be adding soon .

Sunspot AR1890 has been very active having produced 3 X-class flares in 5 days.  Here are some images of AR1890.  Unfortunately there was no flare activity when I was imaging.

Here is a chart that compares the last 3 solar cycles with the current cycle 24.
Solar cycle start dates - 21 - June, 1976, 22 - September, 1986, 23 - May, 1996, 24 - January, 2008
Chart from - Solen

This solar cycle is quite weak compared to cycles of the recent past.

Here are a few images from November 04, 2013.  I had a short time to image and the seeing was poor so this is all of the images that are worth posting.

November 3 Full Disk

Today has been the first opportunity I have had in the last couple of weeks for any imaging , although the sky was clear the viewing conditions were very poor . It was not a day for any kind of close ups but I did manage to salvage a disk shot for today .

Not much sun lately but  I have a couple of images to post.
