Upgrade: Scope or CCD first?

[vic4loc]

Hi all,

Just got approval from the wife for some spending, I have about $4500 budget . I'm interested in deep space & wide field photography. Currently I have a LX90 8" ACF, taking photos with a non modded Canon 550D, guiding with the orion SSAG & orion OAG.

I'm hoping if I could please get some advise & opinion on whether to upgrade to a scope first or a CCD camera first. Two options I'm looking at are:

1. upgrade to the QSI 583wsg, continue using the LX90 in mean time, OR;

2. upgrade to the Tak FSQ85, continue using the 550D for photography


Thanks,
Victor.

I would upgrade to the CCD first and go the steep learning curve and then later upgrade the scope if you want to call going from 8" to 85mm a upgrade.
Isn't the lx90 fitted on a fork mount?
If so then it is a no brainer and go for the ccd because for the Tak you need a EQ mount.

I started with an LX-90 and now have the QSI583wsg, but moved to a refractor and equatorial mount first using a DSLR.

I'd recommend upgrading your mount and going for a refractor first. It's been said many times that the most important part of an astrophotography rig is your mount. I'm afraid the LX-90 just isn't up to it. The QSI also wouldn't swing through the forks, so you wouldn't be able to image anything closer to the pole than ~-70 DEC.

Thanks for the replies, sorry I forgot to mention earlier, I have purchased a HEQ5 and de-forked my LX90 already.

I'd still go with the Refractor. I've sent you a PM about using the LX-90.

I'd go to a larger diameter refractor and ignore the TAK allure, you then have enough money left over for a decent CCD as well.
Otherwise buy one of the 2nd hand G11s for sale and pop your LX90 on that, get a reducer to bring the length down and you are good to go.
You will then be looking at a new focuser before long though I'd bet.

How does the WO FLT98 or FLT110 compare to the Tak FSQ85/106, are they a class apart and we are comparing apple & orange here?

I personally haven't seen or used a TAK in my life, but I love my FLT98.

Personally I have a flt 132, very happy with it, however..... I don't think I've ever seen a TAK106 owner want to go to a William scope, it's usually the other way. You will also see a much larger premium for that little bit extra quality.

For wide photos maybe better to have good scope but great mount and great camera. Not super great scope and average mount and camera.

[vic4loc]

Do you need a field flattener for the WO FLT98 or FLT110? say suppose if I decide to go for the QSI583 which has the 8300 chip.

I am using a QHY9-M on the FLT98 and yes, I am required to use a field flattener.

Currently using a WO P-Flat4 field flattener. (although yet to have the sky and time to produce a result)
