About the image:
I don't know what's up with the images produced by the RC. They are a lot noisier than refractor images. I suppose it's because of the smaller aperture. Using the same exposure time with this scope will result in less data, probably the reason for the noisy image. And i still don' t know a good technique to deal with the oversampling, and the big magnification. In the summer, i will probably revert back to refractor telescopes.

Fantastic shot of the pinwheel galaxy Tim! I have just got the asiair and wondered the same thing as you about polar alignment. I used to use the ioptron ipolar, but if the pole master has a phone app, I would be interested in that. I’m sure a few of us might be interested in a video about how you got on with it! 😀 Keep up the good work

I have the same GSO 6" RC and went thought the teething period to get the collimation right - now it takes about 10 minutes every now and again. I added a T-Ring tilt adjuster, that way no matter what causes tilt in the image train - gravity pulling on the camera changes the tilt sometimes - as long as the OTA is collimated, it is easy to correct at the T-Ring.

Hi, ich verwende genau das gleiche Teleskop und fast die gleich Pixelgröße wie du hast. Ich kann dir empfehlen, den 0,67x Reducer zu besorgen. Der Sprung von f9 auf f6 bringt mehr als das höhere Sampling. Die Qualität bleibt bei unserem Seeing gleich und das Guiding wird entspannter. Viele Grüße Andreas

@@AstroAddict I have the Orion C6 , and looking into the scope the donut on the secondary is easy to see. Put the laser onto the donut with the primary adjustments and then the secondary return to the laser target (hole) and go between them a few times. I then use a LED light covered with aluminum foil with a very small pin hole for a artificial star, about 100 feet away with a low power eye piece for final adjustment. No guess work and it just takes some time. Can be done during the day with the artificial star both scope and LED in the shade. I can tell when the return beam is right in the center of the donut when it is really round on the laser target. Happy viewing it is worth the time for the views.

@douglassmith1215
@douglassmith1215 3 года назад
@@AstroAddict That's good. Since you looked a bit cramped, you might think about using a shorter guidescope like the 50/200 (instead of the 60/240). Consider also replacing the 120MM Mini with the 290MM Mini since it has smaller pixels (2.9 μm vs 3.75 μm). The normal 290MM USB3.0 camera is an even better choice because you can also use it for planetary imaging. Also it's wide and short instead of thin and long and the cable connection is from the side instead of from the back.

Hello Tim, great vid and image! I just bought the same scope and have same camera. Am quite intimidated by the collimation of said scope I have to say. I have a couple of questions. First, it looks like you used the included spacers, did you use all? Which ones? Second, I tried to check the laser adjustment and found it doesn't project on the wall. Not sure what I'm doing wrong, yes i have the front cap off :). The laser itself doesn't have any adjustment screws so not sure how i'd adjust anyway. Bought the omegon laser recommended. The instructions are terrible for the scope, wonder if it would be worthwhile to get a HG collimater. Was looking for a tilt adapter but seems not available anywhere on the planet. Is it worthwhile? Sorry for the barrage of questions. I do have a small bit to offer. I added a top rail to the top by ADM, VRC6-V series dovetail bar for Astro-Tech 6" RC scope. Fits perfect for this scope. Thanks and great work!
@AstroAddict
@AstroAddict 3 года назад
The number of spacers depends on how much equipment you have between telescope and camera, you have to test that out for yourself. The laser adjustment on the wall is done without the telescope, just with the laser in a 1.25" adapter, which is secured to the table. This way, you can rotate the laser without displacing it. You said you have the same Omegon laser. The screws are hidden underneath some layers of insulator, at the back, close to the battery cap. You have to get that rubbery stuff off with a screwdriver or similar. Don't know who invented that. The collimation is definitely difficult, but it can be done with the method shown in the video. I will take a look at this top rail, thanks for the heads up!

Nice video! I like your videos they are a lot of fun :) Why did you replace the OAG with your guidescope? I ask as I am setting up my RC and I have been between the OAG and guidescope and am thinking its just plane easier to use the guidescope but I want to make the OAG work as I'll get better guiding and therefore smaller stars.

I am curious how much you have invested into your complete astrophotography system as shown in the video. $USD or EU (I can convert).. I use a 1991 vintage (when they were hand made and great) Celestron C8 Schmidt Astrograph tube on an early Celestron Fork mount with wedge and Computer controlled and an early Vixen 90mm achromatic guide scope mounted on top of the Celestron tube. Ps your video is great and so is your English.

Great video and excellent capture! If you happen to see this, like you my 8 inch (203mm) RC has been sitting in a closet for a couple of years. I bought a focuser collimation ring to finally correct the focuser tilt. If I may, do I want to collimate the RC primary and secondary first and then add the focuser tilt ring or do everything at the same time? I am confused on the order I should collimate. Long time subscriber and I appreciate any suggestions you have. Thanks again!

Thanks a lot for making this video. Really helped me out with some problems I've been facing with the same scope. I have one question tho, what attachment are you using to connect the guide scope to the main tube. I have the same model, but my attachment is improvised (still works but not a long-term solution). Also, what is the long red attachment (where the guide scope is connected). I have looked for something like that but even Astroshop wasn't able to give me a good suggestion.
