Focal Reducer on SCT for visual?shawnhar
Unfortunately, no. The Antares f/6.3 SCT reducer is actually a reducer/corrector, meaning it works to correct the coma and curvature inherent in SCT images. As the ACF design you have already corrects for coma and partially for curvature, using this reduc" #6 Spacetravelerx Mercury-Atlas Pos...
I am sure I am not in the right place. However like most people on here I need some help/advice. I have an lx85 scope and mount. 8in. ACF SCT. I have an asi178mc camera and was trying to use it for moon imaging last night. I am new to allot of this but I have practiced ...
like the ASI 183 color, which has a 1 inch sensor. This would seem to double my current FoV. I am assuming, however, that the 1.25 inch nosepiece/reducer now in use would act as a baffle to the 1 inch sensor
image area. The focal reducer accentuates this problem by trying to make the scope see a greater area than the telescope was designed for. There is only so much the scope can see - you wouldn't imagine you could reduce the focal length of the scope so much that you could see 180 ...
So that no focal reducer is required. Ie. SCT for planets and perhaps an 80mm refractor for imaging larger DSOs. Mind you, wouldn't the 8" SCT at f/10 be better for smaller DSOs? Ie. Globular clusters?Ideally, you'd want a perfectly designed telescope that fits the exact FOV that ...
I own the Alan Gee 5.9 reducer/corrector, which is designed for c8 imaging. ... To be clear, is this the model that can be installedinsidethe telescope rear cell baffle tube? Your description didn't make it sound like it was in that configuration. ...
So I tried quickly to put on the telescope a reducer. As said here, the0,5x lensworks for 3/4 of the field of the 533 with 30mm of working distance. TheLong Perng 0.8x Reducerwith 57,5 mm of working distance is really good. Only a little vignette due to the internal baffles of ...
I screw the reducer on the telescope side of a 2" diagonal and use a long focal length Plossl afocally. Here is a picture of one of my setups: https://www.cloudyni...6-132504512554/ If you can find one of these reducers I highly recommend it for use with your Sky 90. The Plos...
I was thinking if i do keep using the 1.25" barlow, i could get the baader click lock adapter for 2" and 3.25" sct, but use the reducer for now, from my edge11 diagonal (to go from 2 to 1.25), then i have an option to pull it out and put a 2"...
