Reducing star bloating using 350D filter removed

[gfletcher]

Hi Guys

What is the simplest way of reducing star bloating when imaging using a "filter removed" 350D through an ED80 ?

Does a CLS clip filter work?

thanks

Would it be okay if i were to attach the IR/UV blocking filter off my webcam onto the end of the direct DSLR adaptor on my ED80.

i.e My Canon T ring attaches to the one end of the adaptor and i fix my IR/UV blocking filter into the opposite end of this adaptor ?

Would that work?

The adaptor i am referring to is as shown in the pics.

When you're imaging through a refractor, you'll need a IR cut filter to cut down on star bloat. Some LP filters have this built in, some don't. It it doesn't, then you can always double stack with an IR cut with the LP filter.

Thanks Tony.

I have both IR blocking and IR/UV blocking filters.

Which should i use for the best effect ?

Not sure to be honest, I think either one would probably do just as well as the other but like I say, not 100% on that.

Experiment I guess!

There are Photoshop techniques as well that help. Noel's Actions star reduction is good and for big beggars use a feathered lasso, curves, pin the curve at background level and drag down the curve just above that. Filters-Distort-Pinch is also effective.)
