Just to update, if anyone is still folowing, I ordered the 8"f4 today as well. So I now have both scopes coming. I will test them both with my DSLR and see if there is a focus issue.

O.k. Just ordered.... 1- 203mm f/5 ota 1- set of 235mm rings 1- cooling fan 1- Baader MPCC III Coma Corrector 1- ADM DUP 15" universal plate Next up will be Scopestuff things. New collimation knobs and a Cheshire collimation tube. Still haven't decided on the focuser yet. Also looking for a 120v plug in converter for the Dew Not controller. Any suggestions?

Custom painted CGE and 10 inch ota with Orion 80-ED.

Uranium235, the 8 inch f/5 doesn't come with rings. Only the f/4. But your right, those cheap Orion rings do work good. And I already have one of the Orion universal wide dovetails. And it's rock solid. But everyone is out of them. I had forgotten about Anthonys dovetails though. I'll have to give him a call. As for the Moonlites..6 years ago, and for many years before that, I bought Moonlites for all my scopes. I always enjoyed them. But back then, I only done visual observing. And only dabbled in astrophotography. I talked to Ron again yesterday and we discussed a CR2 w

Soooo, I guess I'm going to try out the 8" f/5. It's relatively inexpensive so it won't be a big loss if it doesn't turn out to be what I want. Going to have to get tube rings, Losmandy style dovetail, Baader MPCC III and a Moonlite focuser. Also have to invest into sone collimation tools. Not sure on those just yet. Maybe Hotech or Glatter. But I do want a Cheshire to start off with so I can center the secondary once I put the new moonlite on. Guess we shall see how it goes.

This is what I'm getting now. But I want to get a bit closer to my subject to resolve more detail.

Not sure about all that "arc second" stuff or "PP" stuff, but I can answer a few of the other questions. I am imaging with a DSLR. It's a70-D crop camera. Unmodded. The reason I am/was considering a f4 Is the shorter tube length. The f/4 and RC are short. The f/4 is only 30 inches and the f/8 is 22 inches. The F/5 is almost 40 inches. The weight of the three are pretty close at around 16/18 lbs. I am looking at a focal length of around 1000mm to 1200mm. That gives me a pretty good magnification to allow me to frame things like the Orion Nebula and Horsehead, but a

Hi everyone. First post here and I'm looking for insight between the 8" f/4 newtonians and the RC8 astrographs. At the moment I have AZ-EQG mount and a Orion ED-80. I also have a ST-80 and ASI120MM to use for guiding. But haven't set it up yet since my AZ-EQG has been doing 3 min unguided shots so far. That seems to work well in my light polluted area with the 600mm ED80. But once I go up in focal length, I'm sure the guide scope will come in handy. Anyway, I know the 8" f4 newts need a few mods out of the box. Focuser, reinforced ota around the focuser and mirror locks as

Moving this over to beginning imaging so you can delete this post. I would, but not sure how. Thanks.

Thanks everyone. Will head over to a few forums in the next few days and search out some answers to my questions. Hopefully I can make a decision soon and get back to higher power/resolution imaging. Love this hobby. Clear Skies

Recently got back into astrophotography after leaving astronomy for about 6 years. When I got out of astronomy I had a CPC 1100 and a SN10 on a old Atlas mount. I recently purchased an AZ-EQG and a Orion ED-80. I'm really enjoying the wide field images of the ED-80, but it's time to get some bigger aperture to tease out more detail. I'm on the fence between a 8 inch f/4 newtonian or an RC8. So most of my questions will be directly towards that to start off. Thanks again for the add. Clear Skies
