Thanks for clarifying. You are not too late to appeal. You are too early. You have to wait until after you are formally sentenced in order to appeal. At that point you have 30 days to file something called a notice of appeal. All that does is to put the state on notice that you will be appealing your case. Your lawyer can do that for you if you ask and secure you an appellate defender. Your appellate defender will have to order the complete trial transcript and go through it all looking for errors caused by the judge, by the prosecutor and/or by your lawyer that may have cost you the trial. You would generally talk to him or her at some point and tell the lawyer what you think went wrong. He would look for evidence of that as well as other possibilities when he goes through the whole record of the case and trial. Then he would draft the appeal.
Judges don't get annoyed when a defendant appeals. It is his Constitutional right and the trial judge has nothing to do with it. The appeal goes to a different, usually a higher, court. The appeal is done on papers. There's no trial. You never have to be there in the court, and for the most part, neither does your lawyer. The judges read your lawyer's argument as well as the prosecutor's and look at the record for themselves. If your appeal is denied, that's usually it. If your conviction is reversed, you would likely be granted a new trial.
As this appears to be a misdemeanor
trial and getting the official record from the court reporter can take months you may actually end up serving your sentence
before this case could get heard. So an appeal may not get you what you want. However, if you are to be incarcerated after your sentencing, there is such a possibility as bail pending appeal. That would give you the ability to remain out, perhaps until your appeal was decided. This has to be arranged for quickly after the sentencing, so you are going to need to talk to your lawyer about this as well.
It is already 12:30 here where I am and I am turning in for the night shortly. If you have additional follow ups just reply like you did before and I will get to them in the morning.
