Re: More Raptor test images
¿ªÔÆÌåÓýStars are distorted at the edges and corners. Usually due to back focus distance (sensor/telescope). Need to add spacers. Scott Busby Belmont Observatory Spotsylvania, Virginia (540)273-0063

Re: MSRO/RAC Station 3 Raptor images og NGC 2903
Myron & Pete,?

That¡¯s great for a quick test. That is a nice focal length and field of view for all the galaxy groups in the sky right now. I got a little data last night but need to get some calibration frames before stacking.?

Cheers,?

First test images from the MSRO/RAC StellarVue SVX102T-Raptor
Dear RAC, I have been working with Pete Laky to bring another remote telescope online as a combined RAC/MSRO station. This will use a Stellarvue? SVX102T-R (Raptor) which has a hand-figured triplet APO lens and a fiels flattner and focal reducer o bring the telescope to f/5. The camera we are using is a 36 MGb QHY 367 Pro C (full sized DSLR chip).It is mounted on an EQ-6 Pro mount. Riding onboard the OTA is the mini-computer (1 Tb Beelink 18v) and a Pegasus Powerbox. Last night was our first night under the stars with this rig. It was a shakedown session with lots of unknowns. really I just wanted to see what kind of field of view we can get and how the autoguiding would work. I only roughly polar aligned and relied on autoguiding to do the rest. Im happy to report 5 minute guided subs were obtained with perfectly round stars! The camera also performed well. It is very sensitive! However, the chip is so large that there is a fair amount of vignetting and fiels curvature. This is what causes the oval stars at the edges of the images. However, once the correct spacing is obtained the images should have pinpoint stars to the edge! I am enclosing two of the test images here. Both have been greatly cropped from the original size. Ill include a full frame of NGC 2903 in my next email that will show the immense field of view-yet still if one zooms in- nearly seeing limited detail is captured! Pete has generously placed the StellarVue "Raptor", QHY 367 Pro, EQ-6 Pro Mount, and telecompressor/field flattener on long term loan to MSRO. This station will be available for RAC members to use just as is the currently operational 10" RC in Station 2. The images were obtained by stacking? 24 5-minute guided subs with the camera running at full resolution (binned 1x1). Zooming in will reveal more detail!? Ill send other images out soon. Remember-these are only test images and have imperfections. But I thought they were still interesting enough to send out. Pete and I would both like to see more club members delve into remote imaging.? Myron |

Kudos to you and your worker bees who have accomplished so much. These two scopes are impressive indeed! On Mar 23, 2025, at 16:11, Myron Wasiuta via groups.io <myrnteryx4@...> wrote: |
Re: The future RAC imaging telescope
Myron, The new scopes look great Myron!? ?Appreciate your hard work to make this possible.? The new capabilities for science and imaging exploration will be awesome. The jack looks?like the perfect solution! Pete On Sun, Mar 23, 2025 at 4:11?PM Myron Wasiuta via <myrnteryx4=[email protected]> wrote:

The future RAC imaging telescope
?
Dear RAC, Here¡¯s the solution Pete and I came up with to move the big 14¡± Celestron/ASKO in and out of the garage for star testing. A pallet jack from Northern Tools! Works great. I¡¯m hoping to get some testing in soon but my immediate project is to get the new MSRO Station 3 online. I¡¯m including a picture of the scope on the test dolly. It¡¯s a Stellarvue SVX102T-R ( hand figured triplet apo optics!)with a QHY 367 M Pro one shot color cmos camera. It¡¯s got a DSLR sized sensor. With the field flattener we should get sharp stars to the edge! Thanks Pete for the generous support on making MSRO/RAC Station 3 a possibility! |
MSRO Station 3
Dear RAC,
At last nights meeting during the MSRO report I discussed progress on our new Station 3 astrophotography setup. It uses a Stellarvue 102mm f/7 ( will be soon f5) SVX102T- Raptor and ASI 2600 MC duo OSC. Here¡¯s a quick picture of the setup in its enclosure. This image was taken before the camera and electronic focuser were added. Pete and I just wanted to make sure it would fit in the enclosure. Hopefully this station will be online soon for members to use. Myron |
Link to March 2025 RAC Meeting Recording
Dear RAC<
Enclosed is the zoom meeting link for our March 2025 meeting and program held last night. We discussed activities at MSRO, and members shared their lunar eclipse stories. Finally, I gave a presentation and presented B band light curves of the recurrent nova T Corona Borealis (T CrB). Myron Passcode: SV^a3kz^ |
M101
Hi Everyone! MSRO 2 is performing super well right now - the go-to is spot-on and the improved polar alignment allows for much better long-duration collection.? Attached is M101 that I imaged last night.? Follow-on work would be to gather additional IR frames and use them as a luminance channel. Pete |

NGC 2903 and Dwarf Galaxy KKH 51
Hello Everyone! Myron nicely touched up the polar alignment on MSRO 2 which has made it possible to do longer stretches of unadjusted imaging so last night I took a crack at NGC 2903 early in the night.? In the attached image you'll see a fuzzball off to the side of the barred spiral galaxy NGC 2903...that's dwarf galaxy KKH 51. Thanks! Pete Laky |
March 2025 Meeting and Program

Re: Lunar Eclipse photos
I was in Richmond and the skies were clear at the beginning until clouds moved in about half way to totality...but satellite images showed it was clear just west of Richmond, so I drove? out I-64 to Rt 522 in Gum Springs and was able to see totality for about 10?minutes before the clouds caught up with me! My best pic is attached!? It was a long night!!! Got to bed a little after 4:00...though did take a nap from?@11-1:00?. No telescope...just taken with my Nikon 70-200 and cropped/processed in Lightroom. Claire On Fri, Mar 14, 2025 at 4:09?AM Myron Wasiuta via <myrnteryx4=[email protected]> wrote:

Eclipse
Sent from my iPhone I got a few pictures from start until clouds set in. I used an old celestron gt 90 refractor and cannon m50 camera.
