Newb here. I have settled on my first telescope being the 4SE or 6SE and I have a Sony Alpha 300 DSLR I would like to be able to connect to play around with AP. I am barely starting to grasp the terminology involved with telescopes in general but it seems connecting a camera to a telescope is a whole different ball game.
It seems as though the 4SE has a separate eyepiece and camera attachment? Looks like you can just flip a knob to swap between the viewer and camera? Whereas the 6SE it appears that you have to remove the whole eyepiece to connect the camera. After reading some reviews everyone says they immediately wanted a more powerful telescope so I am thinking the 6SE may be the way to go but I really don't like the idea of having to swap back and forth by removing the eyepiece, is there an after-market accessory that would allow it to work more like the 4SE (flip a switch from viewer to camera and back)?
And I guess my other question is are the optics really that much better on the 6SE that it would be worth the hassle when connecting the camera? I see that the light gathering capability and magnification are better but how perceivable is that difference? My goal is to do some moon viewing but it would be great to see some cool deep space objects too. +
One final thought, how much does the auto star tracking feature help or hurt the image quality? I mean on a 20 second+ exposure the object is going to move some amount, is the Nexstar tracking system really able to keep the object that precisely still in the optics? Or should I just expect to get blurry spots of light when photographing deep space objects?

Only used a handful of times as I switched from using the DSLR to a ZWO camera, so is in perfect condition. Fit's all Sony Alpha 7 cameras (A7, A7R, A7S etc) and is suitable for cameras which have been astro modified. Retail price is £200 but will accept £120 Will post First Class Signed For (UK Only) and payment can be made via PayPal or Bank Transfer Thanks for looking!
A petition is now online against the Star Eater.
It has been proposed by myself and reviewed by Laurent Laveder, Thierry Legault, Ian Norman, Damian Peach, Aaron D. Priest and Babak Takeshi.
We invite you to sign it and share it to the max:
hi all, thought I'd share a wide field of mine captured on Saturday night (13 Oct) It's another Cassiopeia widefield - is it me or are there loads of us imaging this constellation recently? Shot with my Sony Alpha 200, Sigma 28-70mm F2.8 lens @ 50mm wide open, ISO 800. IIRC it's total of 65 x 20 second lights, 60x 20sec darks and 20x 1/4000sec bias all stacked with DSS and post-processed in PhotoShop CS4. Solved by Astrometry with the following details:
(RA, Dec) center:(19.3779150171, 61.1835725999) degrees
(RA, Dec) center (H:M:S, D:M:S):(01:17:30.700, +61:11:0.861)
Orientation:158.33 deg E of N
Pixel scale:44.52 arcsec/pixel
Field size :25.33 x 16.30 degrees
Your field contains:
The star Caph (bCas)
The star Schedar (aCas)
The star γCas
The star Ruchbah (δCas)
The star Navi (εCas)
The star ηCas
The star ζCas
The star ηPer
The star κCas
The star θCas
NGC 869 / Double cluster
NGC 884 / Double cluster

and the un-annotated version for the purists:
If you think there's more data to pull out, or would like to have a go, I have the raw TIFF file saved from DSS uploaded to my DropBox and can post a link if you want to have a go with it.
