If you are looking for camera accesories, I recommend the ASI6200MC camera.  I use it on my FLT91.    For dark skies, go across the Hood Canal bridge and head down Hwy 101 to Quilcene.  turn off on Penny Creek rd and get up on the hillside.  You have a great open area to the south for viewing.

I would reach out and see if you have a local astronomical society or club in your area. They probably have some good ideas for places to observe or may have their own observatory.  

As for accessories it depends on what you would like to do. If you want to do imaging you need a camera. I like the ASI2600MC but others will work as well. I also use the ASI Air as the control computer for my mount and cameras.

I use mine at full FL, so I have the 68III flattener. Other than that, I just use a ZWO focuser.

The key things you will want to find include:

Mount
Flattener
AP camera
Guide scope and camera
Computer to control scope stuff

iOptron makes great mounts, and their more recent entries do not usually require a counter weight.  Today I use the HEM27 with my ZWO FF107 (similar to the WO 91) as well as with other bigger scopes.  The HEM27 also has a built-in polar scope, which makes doing a PA much easier.

Get the WO flattener for the 91.

I use a ZWO ASI2600MC camera, which is hard to beat.

WO has some great guide scopes.  I use the WO 50mm model with a ZWO ASI678MM camera.  I also have the WO 32mm guide scope for smaller shorter focal length scope setups.

I use a miniPC at the scope for all control and capture duties.  I have a powered USB hub velcrowed to the tripod, which makes connections much easier.  I used to have a ZWO ASIAIR, but found the miniPC worked better for me (wider range of software can be used).

Being older now, I want to be inside doing all control activities (warm in winter and cooler in summer). I use a WiFi adapter at the scope and a Jackery power model for all power needs.  This means that there are no wires outside the footprint of the tripod.

I've got the FLT91 with the 68III flattener. I had an ASI6200MM-P on it, but changed it to the 2600MC-P. Re: slight vignetting in the corners. Moving the 6200 to the UltraCat 108 with a larger image circle as soon as it comes out. I tried using the 6200 with an ASIair+ and it would time out on autofocus and alignment. The 120 meg files are more than the ASIair can handle. Also while the image was processing and displaying to screen, the AA+ would disconnect and reconnect. I also have the 6AIII reducer, but no longer use it for several reasons. One being that once the image train is working, tilt adjusted and backfocus set, I don't dink with it. I currently have an ASI2600MC-P on it and love it. You can't go wrong with the ZWO AM5n mount. I have the AM5 and the ease of use is unbeatable, although PA can be a little unfriendly when cinching it down. It tends to move, so technique is key to  success. I since have moved the FLT91 to a WarpAstron WD-20 mount and run NINA on a Ryzen 7, scope mounted mini PC. It is OnStep based, so unless you have a lot of patience getting use to the intricacies of that mount, I wouldn't recommend it. Having said that, I hated it for 2 months and now I love it. Kudos on the ZWO focuser. I found that I was mostly out of focus when relying on my poor vision and a Bahtinov mask. Now, every scope I have gets the auto focus. A rotator is really nice. I have the Pegasus on my FLT91, but plan on ordering a couple of the new ZWO CAAs for other scopes running ASIair+. Pegasus has some nice power and USB hub solutions and I use the UPBv3 for the FLT91. Filter wheels keep you from having to handle your expensive filters. I tried the filter drawer path and dropped a filter in the dirt one night. Ruined it and have gone filter wheel on all my scopes. Finally, don't be shy… get that credit card out and buy, buy, buy. smile

Depends on which country you reside in. I live in the US and have two main sources: Woodland Hills (telescopes.net), Agena Astro (agenaastro.com). Others might choose differently.

I like Agena or Highpoint prices tend to be comparable between them.
