Markarian’s Galaxy Chain Area with Ultra-Mini Finder

Markarians Galaxy Chain Area – 30×15 sec, Ultra-Mini finder with AR0130 Toupcam color guider/camera.

Here is another one of those experiments I do.  LoL.  This time it was with a software program called SharpCap.  It can capture images from planetary/guider cameras like the Touptek, ASI or ZWO cameras.   Sharpcap’s claim to fame is the ability to stack the images you take on the fly so that you can almost get a “live-view” like experience.  I thought it was neat and easy to use.

This is only 7.5 minutes worth of exposure, so it is not really that deep.   But, it is interesting to be able to get this much with an under $200 camera and a small finder scope.

I also captured 7 x 15 sec exposures of M13 in a live stack.   Not quite enough data in the stack for good star colors with just 1.75 minutes of exposure , unfortunately.    But, it shows the globular well enough.    Check it out:

NGC 2903 – Very Wide Field

NGC 2903 on Feb 15, 2017. 38×180 @ ISO 200, TV-85 at F/5.6, Canon T3, Atlas EQ-G w/EQMOD.

I needed to test guiding with exposures of 3 minutes or longer, so I used NGC 2903 since it was in a convenient location.  This size object needs more image scale to show it better, of course.   But, I kind of like the wide view that shows the galaxy and star field in context.

Btw, in this image, north is to the left.  Also, if you noticed, another small galaxy, NGC 2916, is also visible in this image.   It is below and slightly left of NGC 2903 in this view.

M101 Spiral Galaxy in Ursa Major

M101 on Jan 29, 2017. 23×60 sec @ ISO 800, TV-85 at F/5.6, Canon T3, Atlas EQ-G w/EQMOD.

Here’s one I have not shot in a while.   I was hoping it would come out better, but unfortunately, I lost quite a few of the sub-images to bad guiding.  I was supposed to get 40 or more, but only 23 were good enough to use.

UPDATE:

M101 with more time added. 64×60 @ ISO 400 and 23×60 @ ISO 800 or 87 minutes total.

I was able to shoot this again and get lots more sub-images.   Not too bad considering the light pollution that I had to endure.

M51 Spiral Galaxy Red Zone Image

M51 on Jan 24, 2017. 40×60 sec @ ISO 400, TV-85 at F/5.6, Canon T3, Atlas EQ-G w/EQMOD.

Another Bortle Red Zone image with a relatively short exposure of 40 minutes in 1 minute subs.   I have another batch of 1 minute subs taken at ISO 800 to add to this, but here is the preliminary image for the time being.

Update:

M51 on Jan 24, 2017. Close-up crop. 40×60 sec @ ISO 400 and 40×60 sec @ ISO 800, TV-85 at F/5.6, Canon T3, Atlas EQ-G w/EQMOD.
M51 Full Frame.

The additional 40×60 sec @ ISO 800 subs-images are added into the mix and the updated full frame image and a close-in crop are above.   🙂

Just for fun, I added the above image with 2 previous images of M51 taken with bigger scopes and the results are below:

M51 Combined Data. C-8, SN-8 and TV-85 scopes with DSI and two Canon Cameras.

The Great Andromeda Galaxy – Combined Data

The Great Andromeda Galaxy. 3-panel mosaic taken with a SN-8 and data taken with TV-85 combined.

Data from a 3 panel mosaic taken with a Meade SN-8 telescope back in 2007 was combined with data taken with a Televue TV-85 from 2011.  I used Registar and was able to match the data to the base image, which was the 3-panel mosaic.

I like the way it came out and the orientation is in the classic style for M31.   Thinking about it further, it might be a good project for me to get even more data and add in everything together to get one deep image.    Hmmm…
