Hi

I have a 60mm altair lightwave triplet which is 420mm FL at F7. I use a 183mc pro. Will an upgrade to a Redcat 51 be a great improvement? I "great" is dependant on the individual but i want to get some view

Thank you

Sure.  Send me your last five years tax returns, and allow me to read your mind.  <smile>

 

Like _many_ equipment decisions, just a personal choice, not one to be solved with a survey.

The Redcat has a FL of 250mm so do you want a wider field of view? or are you unhappy with the scope you currently have?

 

I was not aware that Altair did a 60mm APO they do a 60mm doublet F6 so not sure which scope you have? Are you using the field flattener with the Altair? if so I think you need to space this quite accurately to get the best results.

 

Personally I would not go down in aperture myself, I would be looking at something like a 80mm APO F6 which with a reducer would give around F4.8

 

If I wanted a FL of 250mm I would just use a camera lens.

Wider,faster and lighter. The Altair is lightwave 60mm F7 triplet. I think its about 6-7 years old weights about 3.5kg

If you want to go wider, faster, lighter then the Redcat looks a good choice.
