Very nice.

 

Do you use flats to reduce vignetting with the 80ED?

 

Thank you.  No flats or darks were used.

Located on the preceding side, NGC 2207 is the brighter and larger of two interacting galaxies with a 1.5' x 1' halo elongated ENE-WSW and containing a bright core. IC 2163, near NGC 2207's eastern edge, is a fairly noticeable but small nodule, oval-shaped ESE-WNW.

I had a great session 2 nights ago with really clear views. I finally got plate solving working in SharpCap which almost feels like cheating after months of playing hunt-the-fuzzy when the go-to's were off. I was able to view 18 different targets over the course of the night. Just wanted to post 2 of my favorites here starting with Bode's galaxy which I really liked:

Challenged myself to find the tiny Calabash nebula and I think I got it, to the lower right of the nice planetary nebula NGC2438 (34 x 18s @ 403 gain)

I am getting back in after months of lousy observing weather.

I scanned through the recent images and was really impressed with what you guys have been doing. On one extreme we have Saguaro with a 14" f2. What a treat! So many spectacular shots (M78 and lil Rosette, wow). And at the other extreme we have the guys with small refractors proving that you don't need large aperture to get some really nice shots. And some of the first attempts look like they have been doing doing it forever.

While you were all having fun, I took advantage of the weather to upgrade my monstrosity to be remotely controllable using a home built OnStep controller. The mount and focusers are now ASCOM compatible via either USB or wireless link. And I built a warm room so I don't have to fight the bugs and weather.

My shots will be from another extreme, 16in aperture and 2000mm focal length (f5). Not much good for the wide angle shots, but great for getting detail.

We had a break in the weather last week and I had a chance to see what it can do. My upcoming images were all taken with a 16in Sky Watcher Newt on an updated 1960s mount, unmodified Canon t4i, GSO coma corrector, no filters and dark skies. All images were processed on the fly with AT/DSS and saved as viewed. All have either been cropped or resized for the forum. Click on the images for other details and to expand.

After much hemming and hawing, I managed to get myself together and brave the cold New England winter and set up my equipment to gather a few DSO's. The outside temp was near 20 degrees F, +/- 3 degrees. Clear skies with a 1st quarter moon, minor clouds drifting to the south.

 

To get an idea of what was captured and the details, just mouse over each pic.

 

My equipment was: Nexstar C8, ZEQ25 mount, ASI294MC camera, Laptop running SharpCap 3.2. Processing was done on the fly. I cropped the images and converted to JPEG.

Although I have the Nexstar 8SE telescope, I may upgrade to the 9.25 sometime this year or the Meade 10" LX200 ACF OTA.

NGC1514 the crystal ball nebula

This month's LVAS observers challenge object.

 

16s x 28 =448s @max gain

gallery_280529_10253_51410.jpg

 

RT224 camera in a Meade mini lightbridge 114mm, on an Onstep converted Vixen Super Polaris.

 

On Jan 11th I brought my EAA set up to my astronomy club's club house and set it up for remote access as a test for future sessions. The connection worked and a couple of interested members and I sat in the warm club house and hunted down the LVAS challenge object of the month. In the fray I ended up applying the wrong dark frame so there was a bit of amp glow and some hot pixels. 

 

we were able to see the beautiful color and lobed nature of the inner shell of gas, but we weren't able to tease out the fainter larger outer shell.  

 

After that I tried to show them a couple galaxies on the other side of the meridian, but the grease in my mount got so cold that my motors lost steps and the mount lost alignment. (I still have some tuning to do.)  That ended the EAA session and we went outside to join the visual observers.

 

I got to compare the view of ngc1514 in a 16" dob. The bright central star and inner shell were clearly visible. There were hints of splotchyness, especially the darker hole to the south. I couldn't resolve the apparent double. 

 

It was a fun night, I hope to do another EAA session for the members again. I think with the cold weather the turn out might be good.

 

-Corey

My question is how do you get SharpCap to be black? When I choose night colors, it's red, and and it dims the image at the same time. How you doing that?
