The Tasco 9F configured for imaging...

The mount proved to be suitably stable and the 2-axis slow motion controls were easy to use and very effective.

 

Fun stuff!

I tried an experiment last weekend....I used my trusty old C8 with an ASI482MC camera to shoot galaxies "up close and personal".

 

The seeing was not too good and there are other problems but I think it was a success and I will be working with this setup more during galaxy season.

Great shot!  I'd love to see that much detail from my backyard.

An old scope with some bordering on old imaging:

 

I used my Meade 2045/LX3 on a Davis and Sanford tripod about 11 years ago, to take this pic with my "old" Canon T1i of the NA nebula:  5460040-NA_Nebula_55800.jpg

 

My note from back then:  "The nice thing about this scope is that it has a hand controller for slow motions in both axes. It predates autoguiders, though, so one has to guide manually. Since I don't have a guidescope for it, and I wasn't able to find anything with the off-axis guider, I mounted my Canon T1i piggyback and guided through the scope with a Pt Grey Scorpion camera, using the reticle in Astro IIDC to keep the guide star centered.

Here's a wide field shot of Cygnus taken last summer with the 55-200 zoom lens set at 55mm. A single 10 minute exposure."

 

Here's that scope:

This is quick image of the waxing crescent moon taken during twilight with my Unitron 155c and QHY 367c Pro full frame camera. This shows the exceptionally sharp image from the Unitron with no hint of chromatic aberrations. Wonderful scopes!

M3 (4-24-2023)-2j.jpg

 

M3 is a beautiful example of a globular cluster in a relatively lonely stretch of sky. The cluster is a member of the galactic halo and spends much of its time orbiting well outside the plane of the galaxy. It is presently 33,000 light years away from us, 40,000 light years from the galactic core, and 33,000 light years ‘above’ the galactic plane. Home to about 500,000 stars, M3 is relatively young as globular clusters go with an estimated age of 8 billion years.

 

This was the first in a series of test images taken with my Unitron 155c using a cooled full-frame camera. What this system lacks in speed it more than makes up for it in field quality. The star shapes across the field are simply gorgeous!

I have this old (probably ~50 years) 60mm x 700mm OTA, not completely original - I upgraded the finderscope to 6x30, retrofitted a 1.25" focuser, and replaced the original dented dewshield. It rides on a Mizar mount with a homemade plywood cradle. Pictured with a Baader solar film filter on it.

Used it today to image the sun with a 15mm Plossl, #15 yellow filter, iPhone 11 used afocal.

We all know the reputation of the Criterion scopes. I have had this thing, well, forever and it never did a bad job for me back in the day. So earlier this spring I tore it apart, cleaned everything and reassembled. Along the way I discovered that the primary had become loose in the mirror cell holder which obviously didn't help ANY aspect of its functionality. After correcting this and a few more issues I put it back together and crossed my fingers. Not sure how we all ran the manual scopes back in the 80s. I worked until 2 a.m. capturing M3 in Canes Venatici, getting exposures, focuses and tracking speed as close as possible. The results are...I'd say average for this scope, maybe not to par for the C8's for that era. I wish it was better, but I can say I'm not displeased. Maybe another 42 years of life remains in her??? lol.gif

M13 (4-24-2023)-1j.jpg

 

This is M13, the Great Cluster in Hercules. If you look carefully you can glimpse the tiny galaxy NGC 6207 (Mv 11.6) in the upper left corner of this field. What appears to be a dust lane drapes to the lower left across the cluster. This is a very unusual feature for a globular cluster and it is not clear if this is actually associated with M13 or simply lies in the line of sight with the cluster.

M53 (4-26-2023)-1j.jpg

 

M53 is a moderately bright and rich globular cluster located just to the northeast of Alpha Comae Berenices (Diadem). Located approximately 60,000 light years from the galactic center and 58,000 light years from the sun, M53 is one of the more distant globular clusters.

 

This was the third and final image from a set taken with my 155 and full-frame QHY367c Pro. I was curious how well a cooled camera would work with the scope, and it work pretty well! The field quality even with a larg sensor is wonderful. However, looking back at some earlier images I think that my EOS Ra DSLR is a bit better match and simpler to use, so I'm probably going to go back to using that camera on this scope.

 

It's nice to have options. :)

 

Enjoy!

M53 is a moderately bright and rich globular cluster located just to the northeast of Alpha Comae Berenices (Diadem).

 

Well worth observing -- with a 6" or larger scope.  Back in my small refractor days, I didn't pay much attention to it; but, my first views of M53 in my old Meade 826, were jaw-droppers!  So... Rich!  [... and, this was in town.]

all these clusters makes me think it would be kind of fun to do an object of the week thread and then share photos of the same object taken with different classic gear.

OMG beautiful shots!

They say the SCT is a camera lens first telescope second I'm a believer!

You astrophotographers I'm sure have a lot to do with it, but still the detail needs to be there

to capture it.

Thank you guys! Clamship is right. A lot has to do with the telescope and also the seeing. This particular scruffy and rescued Celestar has very good optical performance. The tracking is not great. I need to correct with a homebuilt hand controller most of the time and only in RA. The camera helps because it has a fast capture rate. The images are the result of 3000 frames processed in Registax 6. The seeing was also very good.

Hi ,I had a great observing session with the 26” Leander-McCormick refractor a few nights ago and wanted to share one of my images obtained. We observed other lunar features as well as Jupiter and Saturn. It’s somewhat challenging to image with this telescope using a OSC cmos camera as there is a background of defocussed light from the CA. Nonetheless the views were stunning as this image hints at!

You might try processing the green channel separately, use it for the luminance, and colorize it with the RGB image.
